hour, the border crisis front and center. and not just at the border. it's now a massive issue in cities across the united states. in new york city around 600 migrants are showing up every single day. in chicago plans to bring in military-grade tents as migrants crowd city sidewalks. democratic leaders in both of these big cities are going to the border themselves. just as the biden white house announces a plan to build more border barriers. and police say a man showed up at wisconsin's state capitol with a gun looking for the governor. what he did after his arrest is just as shocking. but first -- donald trump is now weighing a trip to capitol hill, this time without the violent mob, though is injecting himself into maybe what he knows best, chaos. this one is stirred up by republicans who have brought the house to a standstill as they mull over who should be their next speaker after they got rid of the last one. let's get right to cnn's manu raju live on capitol hill. and manu, long-time republican lawmaker steve scalise and jim jordan seem to be the front-runners right now but they're taking quite different approaches to this race. >> yeah, jordan has been a bit more visible in this race. he's done some media appearances. scalise has been very quiet. he's been moving mostly behind the scenes. although this is mostly a behind-the-scenes effort that both men are waging, trying to go member by member to lock down the support. talking to various factions, various groups within the larger house republican conference and making the pitch about why they believe they can unite this badly divided conference. there are many questions that members have about their policies, the decisions they're going to make, how to avoid a government shutdown and how to avoid what happened on the house floor just two days ago when kevin mccarthy became the first speaker ever ousted by his own colleagues on a floor vote. all these questions come as these two men are trying to essentially get a majority of the 221 house republicans to vote for them in a secret ballot election next week. that will be the nominating contest. after they are nominated by their conference then they go to the house floor for a full vote. and that's when things will get tricky, jake, because right now the house is 433 members with two vacancies. that means they can only afford to lose four republican votes on the house floor and if there are more than four we can see what happened to kevin mccarthy happen to either of these candidates, which is why these discussions right now are so critical, to lock down the support and make some promises to these members. otherwise, if these members don't like what they're hearing, then they may undercut that bid for the speakership, jake. >> and manu, you're talking to republicans who say that the threshold to bring a vote to kick out the speaker, the motion to vacate, or mtv, that should be much, much higher than just one person. how much of a factor is that going to play in their votes? >> this is a huge factor, jake. a number of these more moderate members, a number of these members who are close to kevin mccarthy simply do not want to see the matt gaetzes of the world use this again for another speaker, are calling on the changes to the house rules to make it a majority of the house republican conference who could actually call for such a vote ousting the speaker. but jake, also we're hearing from some of those hard right members that say they are willing to get rid of the so-called motion to vacate if jim jordan is their preference, if he becomes elected speaker. but it may be different if steve scalise gets it. he could potentially be in the same situation unless there's agreement among the conference to change the rules here. but a big issue for a lot of these members as they weigh their vote. >> cnn's manu raju, thanks so much. joining us now to discuss, republican california congressman david valadao. he was one of the ten republicans who voted to impeach then president trump over the january 6th insurrection. congressman, so your district borders that of congressman mccarthy, the former speaker. you're friends. mccarthy says he's not going to run for speaker again. so you're going to have to make a decision. have you decided if you are team scalise or team jordan? >> no, i have not. i think we've got a few great candidates running. obviously i'm going to try to take as much time on this as possible. but obviously us not being in d.c. has not changed the amount of communication. i mean, the amount of phone calls going on right now, the amount of zoom meetings that we're having amongst our groups. there's just a lot going on. >> politico reports that mccarthy and scalise have been at odds with each other for years and during mccarthy's january bid for speaker, which went to 15 ballots, quote, mccarthy allies privately vented that scalise wasn't doing enough to help mccarthy. if that's true and mccarthy starts helping jordan out, could you be convinced to be team jordan because of your friendship with mccarthy? >> you know, i've always made my decisions based off what i thought was best. obviously, kevin has been a really strong ally, and i don't think i'd be in congress without him. but i have to always do what i think is best for me and the district that i'm elected to represent. yes, we border but our districts are very, very different in the way that their politics play out. i've got to always do what i have to do. >> so a lot of your colleagues, as i don't need to tell you, are very, very frustrated with not just the eight members of congress, republicans who voted against speaker mccarthy but also just the degree of deference that mccarthy gave the more extremist elements of your party. take a listen to your fellow republican congressman dusty johnson on cnn earlier today. >> we don't change the foundational problems within our conference, it's just going to be the same stupid clown car with a different driver. i don't think the pyromaniacs are going to be satisfied after they've burned down one house. i think they're going to have an itching to go burn down a couple more. >> do you agree that there are, quote, foundational problems, the clown car, the pyromaniacs, whatever you want to call them? and if so is a week enough time to solve them? >> i don't know if a week's long enough. but the issue is we don't have a whole week to waste. we've got to get back to work. we were given a 45-day window to get the government funded. we've got a farm bill. we've got faa reauthorization. we've got national defense reauthorization act. we've got a lot of really important topics that the american people need us to solve. so we need to get this, as dusty said, clown car going again as quickly as possible. >> so your colleague from florida, who's one of the eight, matt gaetz, says he is open to raising the threshold to kick out a speaker if republicans are willing to negotiate on some of the anti-corruption reforms laid out by one of your other fellow californians, democrat ro khanna. and this includes a ban on congressional stock trading, a 12-year term limit for members of congress, a ban on political donations from lobbyists or pacs. seriously, i mean, might you be open to some of those? i don't know if a ban on congrea ban on political donations from lobbyists or pacs sounds so crazy. >> no, none of those ideas sound that crazy. but the reality is there's always a way for people to have their crazy way of making their decisions to make their decisions. and sadly, a lot of these guys are making decisions because they like to see their faces on the tv like i am right now. and sometimes they do it because of online political fund-raising. i mean, we saw that even with the vote this weekend. or earlier this week with mccarthy. we had people as they were speaking on the floor sending out fund-raising texts. even some of my democrat colleagues who were unhappy with the outcome and claimed to be unhappy were sending out their own fund-raising things on the same topic. i mean, i think the only thing that's ever going to solve washington is the american people just paying a little more attention to what's going on and being a little more cautious of what they vote, who they vote into office. because bad people can make bad decisions for whatever reason they want. and the fundamental changes, i mean, honestly we could change the rules, we could change the fund-raising, we could change a lot of things, but someone who wants to do bad things is always going to find a way to do it. and i think we've learned that with a lot of the things we're dealing with today. >> bad people, bad things? like what? like who? >> well, i mean, you just had a story on a minute ago talking about some of the crime situations we've got going on around the country. i just had a friend's father-in-law murdered in a store a couple nights ago here in my hometown. and it was a bad person that did something. and these people are going to find ways of doing it. this guy was standing behind a counter literally looking at a birthday card for a friend and some random person walked up to him and stabbed him for no good reason. why was that person there? he didn't have a gun. he still murdered someone. 80-year-old veteran. and it's a sad situation. these are bad people. and so the decisions are being made, especially in washington. you've got people making decisions i think for the wrong reason. what we saw with matt gaetz and the democrat colleagues love sending out their fund-raising e-mails saying hey, this is a huge problem, these people are crazy. well, every single one of them voted with him. so don't call him crazy if you're voting with them. there was only eight of them and there's 210 republicans that voted the other way. we knew this was a bad strategy, we knew going in, and a lot of us are furious we're getting sent home too. but there was a lot of anger in that room. and i think what garrett graves said is absolutely right. there's a very good chance that there was going to be some fists thrown because people were so angry with the situation. and now we're losing a week of our time when we should be talking about funding the government. we shouldn't be holding the government hostage. people at home who are saying oh, just shut down the government. so you want us to hold our military pay so that people are still having to show up to their bases, to their facilities and continuing to do their job but not get a paycheck? that's a horrible strategy. our strategy should be exactly what some of my colleagues and i disagree with on, passing those appropriation bills, getting those to the senate, negotiating and finding a way to compromise with a democrat senate and democrat president to get these signed into law. these side games and as dusty called it a clown car, it's a sad situation but the reality is we need to get back to work as quickly as possible. >> do you think donald trump should come up to capitol hill as he's talking about doing? >> no, i don't know if that's going to help the situation much right now. i think we've got a great bench of candidates out there. i know a lot of them really well personally and some of them i'm getting to know a little better now. but i think we've got enough candidates in the conference to get -- to find someone who can lead us and work with the -- our colleagues and get something done. >> i know there are a lot of moderate republicans that don't want jim jordan running as the speaker. i mean, everything keeps praising both of them, but i mean, jim jordan -- i mean, jim jordan voted against the cr on friday. he voted in favor of shutting down the government. so you really think that he's a broad-based appeal for the republican conference? >> no, that's a great question. yeah, there was some frustration there. but even in his speech defending mccarthy on the floor the other day he spoke about how that was literally the only option we had left. and i saw a few members in conference that morning when it was being talked about, just the republicans, who got up and spoke in support of that resolution and ended up voting against it. and they make their decisions. and as a person that's taken some tough votes in my career and understands fully what it's like to do what you bleeb is right no matter what, sometimes it sucks to see it. but i'm sure if we look back into scalise's record or i'm sure if we look into kevin hern's record or whoever else, kevin mccarthy's record or even my own, you're going to find something you disagree with. my goal is to try to find the best candidate to get us out of this mess. >> republican from california david valadao. thank you so much. appreciate it. coming up next that disturbing arrest in wisconsin after a man allegedly showed up to the state capitol with a gun not once but twice in one day. also ahead donald trump's newest political target, nikki haley. and he made his plans pretty public knowledge. stay with us. in our national lead a terrifying story out of the wisconsin capitol building, where a man allegedly brought a gun and asked to see the state's governor, only to be arrested, post bail, and then show back up with a rifle. cnn's whitney wilde joins us live. whitney, walk us through how all of this unfolded. >> reporter: so here's what happened, jake. this man went to the madison capitol at 2:00 wednesday. he didn't have a shirt on. he had a gun in a holster and he had a dog on a leash. and he told security there he wanted to talk to the governor. they took him into custody because it is illegal to have a firearm inside the wisconsin state capitol. so he went to jail, he was processed. he posted bail. seven hours later he showed back up at the madison capital, this time with an ak-47 style rifle, again demanding to speak with the governor. police have not expanded on his comments. they have not said whether or not they were threatening. they said only that he wanted to speak with the governor. they took him back into custody, again without incident. he consented to a voluntary search of his backpack, which showed that he had a collapsable -- basically a collapsable police baton in his backpack. and capitol police consider that a weapon. and said that he does not have a concealed carry permit for that weapon. so again they took him back into custody. he was at least charged with that. the latest information we have, jake, is that he was -- they were going to try to get limb to undergo a psychiatric evaluation. many more questions here to learn, jake. but certainly the diligent police at the madison capitol protecting the governor from what could have been a much scarier and much more dangerous incident. tony evers, the governor of wisconsin, saying just that, saying this is not something you ever want to see but he's very grateful for the diligent work of the capitol police in madison. reporters asked him today whether or not the security posture at the madison capitol is going to change, and the governor said that is something he believes that they are certainly looking into, jake. >> showing up the first time wasn't enough of a red flag, apparently, for the psychiatric exam. whitney wild, thank you so much. appreciate it. in our law and justice lead, new moments -- new movement in the fulton county election subversion case in georgia involving former president trump and 18 other co-defendants. attorneys for former trump campaign lawyer sidney powell in court today arguing several motions including to dismiss her case. joining us now is cnn's sara murray. sara, what came out of today's hearing? >> well, the long and short of it is sidney powell and kenneth cheseboro, this other protrump attorney, are still on track to go to trial in this case in just a couple of weeks, later on this month. sidney powell's attorney, you know, sort of presented an early preview of what his defense is going to be as he was trying to get the charges against her dismissed. the judge didn't exactly rule but he very strongly signaled that he was not going to buy powell's motion to dismiss, said she really didn't meet the procedural bar here in terms of alleging some kind of misconduct or whatnot when it came to bringing the indictment. so it's full speed ahead for trial. >> did you hear when parlatore was on the other day, represents bernie kerik and said he has testimony to share that would help with that? >> yeah. i think it's going to be interesting to see the wrangling with the various witnesses. we're starting to see some of that. they mentioned in court today that the prosecution had just offered up a preliminary list of 174 potential witnesses who may come up at trial, and we saw some court filings earlier today with the judge overseeing this case essentially approving the d.a.'s efforts to seek testimony for a handful of out of state -- >> boris epshteyn. >> boris epshteyn is one of the people on the list. lawrence tavis, who is the pennsylvania gop chair who was supposed to serve as a fake elector in pennsylvania but ultimately didn't do so. again, this is the kind of wrangling we're going to see ahead of trial trying to get these witnesses to come in from out of state, trying to force people to testify who clearly don't want to testify. >> i don't know if they watch "the lead" in fani willis's office, but clearly parlatore was trying to signal, call me, you know, for something with bernie kerik. anyway, sara murray, thank you so much. really appreciate it. when donald trump said he would build that wall, joe biden was saying this as a candidate. >> there will not be another foot of wall constructed in my administration. >> no longer true. stay with us. from chrome to duckduckgo.

allegedly. abc news just reported that months after leaving the white house the former president allegedly discussed details about u.s. nuclear submarines with somebody who was a member of his mar-a-lago club who did not have security clearances. that person was reportedly an australian billionaire who shared the information with dozens of other people including foreign officials and journalists. abc news reports all of this information was reported to special counsel jack smith, who is of course investigating trump's handling and alleged mishandling of classified records. we are not yet aware of any response from trump or the australian businessman to abc news. but let us discuss. we have with us former congresswoman barbara comstock, who is insisting that i call her barbara. what's your response to this story? >> well, i'm confident it's true, and things continue to amaze us. not amaze us with donald trump but i think jack smith is doing a very thorough and great job and shows why that case is going to be i think a real problem for donald trump and why this election is going to be very much in play. so for those who think it's a great idea for him to come up to congress next week and it all get in the mix here, it's a really bad idea. things could only get worse up there. >> well, you heard congressman valadao, a republican from california, say that he does not want donald trump to go up to capitol hill. congressman max miller, a former aide to donald trump in the white house, excited to have donald trump come up to capitol hill. >> yeah, i think it depends on where you fall in the maga extremism of the republican caucus right now. donald trump is still the front leader of the republican primary and, you know, some folks still love him. some folks still want to give him the leash to say that the election results of 2020 weren't valid. some folks would have listened to him depending on -- this week with the speaker vote. so people are really taking their clues from donald trump. i think it could cause more chaos for jim jordan and scalise in their speaker run because he could come up and say make me speaker. not that donald trump wants to work that hard really. but it would be a disaster. and this finding that he has given more sensitive information to someone without classified -- >> clearance. >> -- clearance. >> yeah. >> and who needs not know secrets about our national security. is yet again an example of why he doesn't need to go to capitol hill and why he never needs to return to the white house. >> he's unfit. >> and audie, this phrase "shocking but not surprising" is one we have constantly been using in the trump administration. it is shocking that he would do this and yet completely in character. >> it's also easy to be desensitized by it. we're hearing this almost out of context. right? if you're the average person watching him in any given courtroom at any given time, is this case tied to this one? which jack smith one is this? and i think it will be interesting over the next couple of months if these things start to kind of coalesce for people in their minds, that they have a distinct understanding of what it means to violate the law. right? and you'll be hearing from judges more. you'll be hearing actual courtroom discussion more. i think that will be more helpful. because right now it's a blitz of information and not in a good way. >> let's talk about the big news at the border. ashley, as a candidate joe biden promised no more spending on the border wall or border barriers. the money in texas was already approved. it had to be spent. but it seems as though the dhs secretary, mayorkas, acknowledged in his statement that to a degree at least donald trump was right that there do need to be some barriers to at least alleviate the migrant crisis to keep people out. i mean, countries are allowed to have borders. >> yeah, i think joe biden saying he doesn't think the border wall works, i think we need other solutions to stop the influx of migrants coming to the united states. we need to have comprehensive immigration reform. this is not a problem that, you know, just started happening with joe biden's campaign promise in 2020. >> no, of course not. >> it's been going on for decades, and it goes -- it's almost cyclical because if you can't get order on capitol hill to actually legislate and pass comprehensive reform then we're going to -- whoever it is, donald trump, that was his leading phrase, "let's build the wall." or joe biden using the money. we're kind of stuck. >> and in total, more than 17,000 migrants have come to chicago since august 2022 and more than 340 buses. and the democratic mayor says they're expecting up to 20 buses a day but they're never sure. take a listen. >> they're sending buses in the middle of the night. and so that number continues to change throughout the day. >> i have to say, whatever people thought about the -- they were called stunts by desantis of florida and abbott of texas. it has had the effect of getting democrats -- forcing democrats to have skin in the game and realize that this crisis is having a real effect on how places that have this influx, their ability to do anything about it. it is a humanitarian crisis in addition to being all sorts of other kinds of crisis. >> well, and politically this is a good move for joe biden to get a bipartisan solution here. and right now you have sort of this false situation where you have some republicans saying we can't do anything about ukraine because we have a border crisis. >> right. >> this has the makings of -- this is what lindsey graham has been talking about and the senate republicans have been saying. let's fix the border and do more border money in exchange for more ukraine money. so i think this is an ideal situation where you can take a lot of that h r2 and what henry cuellar was talking about earlier today on the show, saying there's a lot of hr2, that border bill that republicans like. let's take pieces of that. there's a lot of technology in there, a lot of things republicans like. and then let's get the ukraine money that we know we need. there's a deal to be had there. and joe biden can -- while republicans are trying to burn down the house, he can be working with henry cuellar and with senate republicans and with reasonable republicans in the house and saying let's make a deal. and he can be the art of the deal here while donald trump is dealing with his legal problems. >> and a little context for what you said. yes, it was a political stunt. but one thing we learned from the reporting here at cnn, rosa flores's amazing, is information does get back down through the chain when it comes to the sort of migrant community. so if you're getting a free bus ticket to new york or chicago or wherever, at a certain point you are now just telling people back home, when you get here, they send you to -- >> to chicago or los angeles. >> yeah. so you are in fact also reinforcing and creating further problems. >> further incentive. yeah. >> and further incentive. and that's something that isn't talked about very much. and you're right. chaos is a ladder and it's probably helpful for democrats to talk about what is often politically, you know, a thankless issue with no real constituency to support it of actually trying to address something in a humane way, meaning beyond just cutting off access -- >> excellent points. you mentioned a second ago burning down the house, a reference to what just happened in the house of representatives. and in light of that i want to bring you some breaking news that i just was told in my earpiece. donald trump just told fox digital that he would accept the job of house speaker for a short period of time while house republicans decide on a permanent replacement. mr. trump said he would be willing to serve for up to 90 days as a unifier. i hesitate to even bring you this news because it seems so preposterous. and yet -- >> i assume some lawyer tried to find out if you could pardon yourself and maybe -- >> right. >> unfortunately, he doesn't know the house rules, which say if you're indicted you cannot be in house leadership. that has been a republican rule that apparently neither he nor some of the republicans know. remember back when tom delay was indicted. he stepped aside from republican leadership. >> is that right? >> that's a rule that's in place. it's been in place for years. you have senator menendez over in the is that the who stepped aside from his leadership role. >> you don't think they would take away the rule? >> if republicans want to lose the house -- listen, i am not a fan obviously of donald trump, will not be voting for him. but if they're going to be doing this they really will be burning down the house. >> this is a disaster. an absolute disaster. that's all. >> just keep burning down the house. >> just four words? >> this is a disaster. >> for them or -- >> america. >> it's for the country. >> for america. >> it's a disaster for everyone. >> republican, independents and democrats. >> for the constitution. for everybody. >> a disaster. >> we can't call everything a disaster. >> that would be a disaster. >> something that is politically embarrassing and probably kicks -- you know, is not necessarily a disaster for all of us. and that's what we're looking at. >> thank you one and all for being here. and need i remind you it is audie cornish thursday. her podcast drops today. so please, everybody listen to it. new data today confirms an alarming trend, one that every single person on the planet needs to know about. stay tuned. our earth matters lead now. september saw numerous extreme weather events from the devastating and deadly flooding in libya to wildfires that continue to burn in canada to an historic downpour flooding parts of new york city. and now new data shows last month was also the hottest september on record. and one climate scientist is calling it absolutely gobsmackingly bananas. this is an alarming trend that has continued now for four consecutive months, meaning 2023 is now on track to becoming the hottest year ever in recorded history. cnn chief climate correspondent bill weir joins me. bill, what factors are driving this extreme heat? >> well, it's not just a little, this new record. it's by a lot. take a look at this bar graph from copernicus. this is the european space weather agency. this is septembers going back to 1940. and for most of those generations it was below average. see what happens there around 2000, it starts going up. and then we are that giant red line on the right side. and scientists are saying that is gobsmackingly bananas right now. it's a combination of fossil fuel pollution over 150 years and el nino just beginning in the pacific, both the natural and the unnatural causes of this giant crisis. but there's amazing good news as well. from the international energy agency. their new report now takes stock of just how fast the world is adopting to clean energy. solar, heat pumps, battery storage, these sorts of things have them predicting now that humanity will hold the warming at about 2.4 degrees warming by 2100. there's still a chance for 1.5. that is considerably good news considering just ten years ago we were talking about, you know, apocalyptic temperatures by 2100. but this shows that we can bend the curve if humanity cares. the technology is there. if humanity finds the will to do this politically. so we're talking in much less dire terms. >> how is the record heat impacting people who work outside? >> well, it's interesting. the university of exeter just did a study on a high-tech chinese factory workers who work inside in air-conditioning, and for every degree the temperature goes up by one celsius productivity goes down by almost 1% because overnight temperatures affect sleep, which affects productivity. so just imagine road crews, as you see there, construction crews in phoenix starting at 4:00 in the morning. farm workers from texas and florida are having to fight for water breaks with local polit politicians. adaptation means survival in this new era we're living in. and both earth care is self-care in a lot of ways, jake. >> bill weir, thanks so much. sticking with this issue, let's talk now to one of the most influential climate scientists on the planet, michael mann. his latest book is "our fragile moment: how lessons from the earth's past can can help us survive the climate crisis." congratulations on the book, michael. despite this year being on track to be the hottest ever recorded, you take as bill just did a cautiously optimistic tone in your book. you write, "the greatest threat is no longer denialism, which is frankly untenable given the impacts that we can all see playing out in real time, but rather doomism, the notion that it's too late to act." so what lessons from the past give you hope that we can actually meet this moment? >> yeah, thanks. it was a great sort of summary that bill provided there. and he emphasized sort of this duality of urgency and agency. the urgency is obvious. it's clear. we're all feeling increasingly dire consequences of fossil fuel burning and the warming planet that that's causing. but as bill alluded to, we have agency as well. we can reduce our carbon emissions enough to avoid crossing into truly catastrophic territory. and when we look to the past, we can see that, you know, earth does have a certain amount of resilience. the earth system, earth's climate has a certain amount of resilience within it. and that's a helpful thing. we've seen that in the past. the climate hasn't spun out of control. it's warmed up substantially when there's been a massive input of carbon dioxide. and that happened 55 million years ago, for example. that was a natural input of carbon dioxide. the planet warmed nearly nine degrees fahrenheit. but it took tens of thousands of years. that's rapid on a geological time frame. we're warming the planet 100 times faster. and that's really the problem. it isn't how warm it is or how high co2 levels are. they've been higher. the planet's been warmer. it's the rate at which we are warming the planet. but we can stop it. if we stop polluting the atmosphere with carbon pollution, the warming of the planet stops and the impacts that we're seeing stop getting worse. we'll still have to contend with those impacts that are baked in, but we can prevent it from getting worse. >> and i think this message that you and bill are conveying today is so important because there are so many young people out there who have this apocalyptic view and it's such a pessimistic view and it can really cause almost a nihilism. and it's important to convey to them no, no, we can make a difference, we can get hold of this. >> yeah, that's absolutely right. and again, when we look to the past, what we find is those extinction events in the past were caused not by runaway warming -- there are some people today who think we've triggered runaway warming, a release of methane we can't stop and all life will be extinct in ten years no matter what we do. that's not true. that's not happening. and it isn't what happened in these past events. what happened in these past events was that there was carbon dioxide, in the past produced by volcanic outgassing, intense periods of volcanism. we are putting carbon dioxide into the atmosphere today through fossil fuel burning. and if we stop fossil fuel burning, we'll stop that which threatens us. that which does threaten us and other living things with dire consequences if we don't rein it in. >> this is a point i really want to get to before i have to say good-bye, which is you say that one of the biggest obstacles to action is the sustained disinformation campaign from the fossil fuel lobby but also you write, "equally culpable are its abettors in the conservative media and none are nor implicated than rupert murdoch." quickly, do you see any evidence that the campaign to discredit climate science is lessening at all? >> you know, it's not lessening. what we're seeing is a shift away from outright denial. we see less denial because we're all seeing the impacts. we're all seeing the consequences. it's very difficult for polluters and those promoting their agenda to deny it's happening. so they've turned to other tactics. delay, deflection. and one of them ironically is doom-mongering. if they can convince us it's too late to do anything about the problem, it potentially leads us down that same path of disengagement. so once again, it comes down to urgency. we see the urgency. we have a crisis on our hands. and agency. we can do something about this. we need action. we need to vote for politicians who will support climate action rather than politicians who will act as rubber stamps for polluters. >> the book again is "our fragile moment." the author is michael mann. good to see you, sir. thanks so much for joining us. >> thank you, jake. back in court. up next, the new fight for the convicted murderer who was the subject of the "serial" podcast. c'mon, we're right there. c'mon baby. it's the only we need. go, go, go, go! ah! touchdown baby! -touchdown! are your neighbors watching the same game? yeah, my 5g home internet delays the game a bit. but you get used to it. try these. they're noise cancelling earmuffs. i stole them from an airport. it's always something with you, man. great! solid! -greek salad? exactly! don't delay the game with verizon or t-mobile 5g home internet. catch it on the xfinity 10g network. adnan sayed, who became famous through the hit podcast, "serial," is fighting to stay out of prison. he spent more than two decades in prison for the 1999 killing of his high school ex-girlfriend. he was freed last year after his conviction was overturned, but in appeals court reinstated his sentence in march after finding her brother had had his rights violated as a victims representative. cnn's jean casarez is here. what happened in court today? >> it was fascinating. first of all, there was all of the major issues were addressed today, one being the family's representative, should he have had the right the time to be able to fly from california to maryland to physically be in the courtroom? should he have been able to be heard? could he have spoken in the courtroom? should he have known what the exculpatory evidence was that was vacating the conviction? he wasn't told of that, and of course the attorneys representing the victim's family said yes, he should have, but the other side, adnan syed said, no, this is moot. he didn't have to physically be in the courtroom. there was no right at all for him to be heard in that courtroom, but then, there was a can of worms opened up in that courtroom today because the attorney for young lee's family said, your honor, there was a hearing that was in the judge's chamber, very close in time to when this all happened, and the prosecution, the defense, the judge was there. no court reporter. nothing was written down. the prosecution, we understand, said, we have exculpatory evidence, we want to vacate the conviction. it was not disclosed at that time what it was, and it was all very quick. the justices took note of that because one even said it appears as though there was a lot of stuff that had been discussed even before that, that plain clothes would be -- civilian clothes would be ready for him. i want you to listen to the maryland supreme court justice, shirley watts, take note of this revelation. >> so, the concern is that this was a hearing that was more than just a disclosure of brady material, that it was an in camera hearing where significant decisions were made that should have been made on the record in the hearing, and that mr. lee, the victim's representative, didn't have an opportunity to participate meaningfully because decisions were made in camera. >> now, this hearing, jake, in the judge's chamber, it was not an issue to really be looked at today, but if it coincides with the victim's right to have notice of what that evidence was, what was said in that hearing, notice that there was going to be a hearing because he didn't even know anything about it, the victim's representative. then, suddenly, this hearing cou could be front and center in this decision. >> briefly, could syed go back to prison? >> it appears to me before that, the judge would have a hearing involving vacating the conviction before that. we'll see. >> all right, jean casarez, thank you so much. we continue to look at how gun violence is affecting american children. today, "the new york times" reports that the rate of firearm fatalities among children under 18 increased by 87% from 2011 through 2021. 87%. it's a sobering statistic that needs repeating. already this year, more than 1,300 of america's children and teenagers have been killed by firearms. this month, cnn is telling some of their stories, stories like that of 16-year-old isaiah carter, who was gunned down near his high school in baltimore in march. his mother describes isaiah as empathetic and a role model for his younger brother and sister. in high school, isaiah joined the air force junior reserve, hoping to join the air force once he graduated. his mother wants you to know that isaiah "was your kid, your daughter, your son." please read the cnn series that profiles a america's youngest victims at cnn.com. a memorial service today for the late democratic senator dianne feinstein of california held in
