"cnn this morning" starts right now. ♪ the tragedy in hawaii is getting worse by the hour. >> overnight, the increase in the death toll up to now 55, and most people we speak with expect it's going to go even higher. >> and very concerned about a lack of warning that we're hearing from some of the residents there. hawaii's governor says that number of dead likely to increase significantly as search and rescue teams go through hundreds od washington are headed to hawaii now. they will be searching for survivors. they are also bringing cadaver dogs. >> we're getting intel now that the rescue effort is severe. and we want to match that need with what we have. our personnel here are highly trained. they train over the course of several years for this very moment to serve. >> and as poppy mentioned, there are serious questions about if and when people were warned to evacuate. some survivors say they didn't get the evacuation orders or the orders came too late. when the flames were already closing in. and we just spoke to one man who said he never heard any sirens. >> i probably wouldn't have been able to grab anything in my house. i don't know if i would have been able to find my car keys, find my phone, find my dog food, whatever. it pinged me as i was getting into my truck to leave, so that warning was completely useless. we have tsunami warnings that i think should have been utilized. i think this could have been handled so much better in so many ways. so many of us residents felt like we had absolutely no warning. >> here's the time line on when social media alerts were sent out. a brush fire was spotted early on tuesday and at 8:38 a.m., the county facebook page put out this message, ordering evacuations around lahaina intermediate school. you see the school marked on the map here, which ended up not being in the area most impacted. about 90 minutes later, the county says the fire is 100% contained. another evacuation message doesn't go out for five hours. we're talking 3:33, when the next one's out. >> our own bill weir got a firsthand look at the destruction. he walked through the burned streets of lahaina. >> this is the historic banyan tree, it looks like it may have been survived. it needs water desperately to survive iright now but for the locals coming down and looking at the damage, this is such a sign of hope that maybe their iconic tree will have lived when so much else is gone here. but the history can never be replaced. right here, this is the first hotel in hawaii, the pioneer hotel, pioneer theater. it's completely gone. right over here was the library. it's just now a stone shell of scorched blocks around front street there, fleetwood, mic fleet wood of the band fleetwood mac. his place is gutted out with flames. it's just unrecognizable. one of the most charming, beloved port cities anywhere in the world is just scorched like a bomb went off. >> wow. like a bomb went off. we'll have much more live with our bill weir in the next hour. our thanks to him. as we mentioned, it's unclear how high the death toll in maui is and how high it could go. >> police don't know how many people are actually missing. >> how many people are still missing at this hour? >> do you want to defer that to me? >> sure. whomever. . >> honestly we don't know. and here's the challenge. there's no power. there's no internet. there's no radio coverage until we get some of those basic things set up. we are not going to have that number. >> tim williams' family has not seen him since he sent them this photo of the inferno closing this as he was evacuating. he's a disabled veteran who uses a wheelchair and crutches to walk. linda's family in massachusetts says they are not heard from her since the fire destroyed her apartment, and they're even more concerned because she has health issues. >> she doesn't get around very well. she needs some assistance, and i just hope that someone was able to get to her and help her to evacuate. they're looking but we have not heard anything yet. and from what i have seen, it looks like their apartment complex is completely gone. >> allen vu is with us now. he lost his home and the place where he worked. his restaurant, where he was the chef there, the fire took both. allen, i'm sorry to speak with you under these circumstances, but i do want to start with at least some good news. there was a question about an employee, a coworker. you did not have any idea where this person was, but you have an update now, tell us about it. >> you know, it came from our tremendous strong leadership from the company. what we first did was make sure that we made sure all of our employees were taken into account from management staff. we made sure that we continuously text and phone called every employee to make sure that they're accounted for. and it was just until today that we were able to contact the final one, which was angelina, and she is currently with her boyfriend north of lahaina now. >> so everybody is accounted for. that is the good news. let me start, though, with when you knew that you couldn't wait this out, that you had to move, where were you, and what was the first indication that this was an emergency that you had to escape from? >> we didn't expect the fire to go through the town this quick. i was with my general manager, jerica in our restaurant, thinking that if the possibility of power coming back, we can salvage our products and our restaurant. we were just getting some work done. i left the bar, restaurant, around 3:00 p.m. with my house mates. they were with me the whole time. and as we were driving to town, we could see that there's smoke coming our way. we drove down on front street towards our house, which is southbound. during that time, there was already an evacuation with bumper to bumper traffic going northbound on front street, going up to the civic center. when we got to our place, we continued to look up at the smoke, and it was just, you know, within minutes we could see the smoke brush, i would say, a half mile through the town. the footage i shared with some of your staff members that the fire went through the town really quick, and when we saw that, it was time to warn everyone in our neighborhood to get out. >> speaking of warning everyone in the neighborhood to get out. it was evident based on what you're describing, the traffic, smoke that you had to make a move, but did you receive any alerts, any warnings officially from the city on your cell phone, anything like that? >> on my cell phone, we had warnings of strong winds and, you know, possible fires, but no real, you know, like the -- no real warning like the amber alerts for the storms that we normally get that would vibrate and make loud noises from our phone. we didn't get any of that. there was no sirens. we had monthly sirens, tsunami. tsunami noises just to make sure the sirens worked every month, but on that day there was no sirens. >> no sirens. so your home is destroyed. your workplace is destroyed. what do you do now? >> well, i'm fortunate enough to be housed in wailuku, which is a town 30 miles away from lahaina, along with my landlord, and house mates and my dog. i'm staying at my coworker's place, marcus, but a lot of us that are displaced from lahaina are staying at a shelter at the war memorial stadium here in town. but right now, you know, we're planning ahead about what to do in the week, what to do in two weeks. there's a lot of plans of being there for the relief support in lahaina when they open up access for everyone to enter because we saw footage of how destructive that place is, and everyone is ready to come back and revive the place. >> we have spoken with people over the last two days, southeseveral days now, that are relying upon their friends, their neighbors, like you are, and we spoke with cole millington earlier who's one of 15 staying at a friend's house. as it relates to the government support, local, state, federal, have you received support? do you know where repyou can ge that? what's the communication from those resources to you? >> well, for me personally, i haven't been, you know, paying attention to a lot of news or radio. but we do hear that, you know, governors talking about sending in help, we heard that there's assistance from our president wanting to send support in. we do know that there's an army and naval base on oahu. as of now, we are seeing very little support from big organizations. we hear that there is coast guards or national guards that's assisting with organization in lahaina. but at the same time, we are in contact with a lot of residents in lahaina that are stuck up north who are out of power, out of water, out of gas. there's no gas. so a lot of civilians, and a lot of people are trying to access into lahaina, northbound or southbound to provide support. >> allen vu, we are happy that you are safe, that angelina is safe, everybody there at the marlan bar, and thank you for spending time with us and telling us your story. be well. >> appreciate it. >> for more information on how you can help hawaii wildfire survivors, go to cnn.com/impact or text hawaii to 707070 to donate. poppy. >> victor, thank you. in just a few hours, trump's team will meet judge tanya chutkan in a courtroom. she's the judge overseeing the 2020 election interference case. this comes as federal prosecutors are hoping to start the trial just ahead of the january 6th anniversary. our elie honig is here with more. what is the significance of today, as they're before the judge kwwho will see this whole thing. >> the case we're focused on here is the federal case brought by doj special counsel jack smith relating to donald trump's effort to steal the 2020 election. now, the main issue in front of the young today is what can donald trump say and do publicly relating to discovery? now, discovery means that in any criminal case, prosecutors have an obligation to turn over all of their evidence, all of their witness statements, all of that documents before trial. jack smith has taken the position there should be a protective order preventing donald trump from speaking publicly about all materials, everything. trump's team has said we should limit that only to sensitive materials, not all materials, and we'll let you, jack smith, tell us which ones are sensitive. no good, you have to be stopped from talking about all the materials. and jack smith cites donald trump's inflammatory social media posts including this infamous one. >> is that realistic, would any other defendant face something like that, you can't talk about anything? >> it's drastic, but jack smith argues it's merited based on the circumstances and the fear that jack smith is we don't want witnesses being intimidated here. there's a secondary issue before the judge today. we have learned there are some, not many, but some classified documents in the january 6th case. this is separate from the mar-a-lago case, all about classified documents. the parties have to work out how they're going to deal with classified documents. this is the first appearance in front of district court judge, tanya chutkan. she understands the defendant's constitutional rights. she has handled prior january 6th cases harshly. >> this is the part i think is going to make today so interesting. she is a big believer in defendants' rights. trial schedule, what are we looking at, they want january 2nd. >> jack smith asked for january 2nd, 2024 . trump has not weighed in yet. this indictment dropped last week. on august 1st, if they do a january 2nd trial, jury selection is going to start here. that would give trump's team four and a half months to prepare. that's a really short amount of time. bigger picture, and here's where it gets sort of crazy, okay, the election is in november 2024. we already have the manhattan d.a.'s trial starting in march. that will go through april. we already have the mar-a-lago trial starting at the end of may, that's going to go through june and july, and now jack smith is saying, let's start the january 6th trial in early january. there's just not room for that. you're not going to get this trial in before march. this is the d.a.'s trial. that one is going to have to move in order for this one to get in early. there's a lot here. >> thank you, stick around. we have a lot to talk about. senator tim scott signs the loyalty pledge and seals his place at the first gop debate. we'll tell you who's in and who is still on the fence. also, huge deal at the supreme court. they have blocked a $6 billion opioid settlement that would give immunity to the family behind purdue pharma, maker of oxycontin. details behind that ruling ahead. ♪ chevy y silverado has what it takes to do it all. with up to 13 3 camera views. and the z71 off-road p package. ♪ you ok?

you would not. talk about how important it really is. >> reporter: well, there's a huge opportunity here for candidates. first of all, the local and national press sort of gather here, and there's a whole sort of free media opportunity for candidates to get a lot of attention, especially those candidates who have been starved for attention in this race. that's one. two, it's also a real opportunity to mix and mingle with voters and have these candidates get their tires kicked, if you will, by the voters. that's what they do in these early states, and i know you played that video at the top of pence getting heckled. i would just say having watched him here yesterday, that was not sort of the typical encounter that he had. he had a very, i would call, successful day at the fair. he seems sort of in his skin and natural at home in this environment. we were at a press availability, and he said for a southern boy from indiana, the iowa sate fair -- state fair is in his strike zone. >> i watched at the des moines register, he was speaking with voters. what should we expect over the next several days as more candidates show up? >> reporter: sort of in line with what david is saying, getting your tires kicked. all of the candidates want to get a little bit of kicking in. they want to engage with all of these voters. we're going to see what mike pence went through, all of the candidates are going to go through the soap box, as well as the fairside chat with the governor of iowa, except for donald trump. he is going to bring his own stage. he's going to do his own thing. just as we saw him do in 2016, you may recall that. certainly he was giving chopper rides. >> to all the kids at the fair that wanted to get on his helicopter. >> right. so he's not going to be doing that as we know of right now, but he's going to be walking through the fair and really sort of creating his own spectacle here and rewriting the rules of what we typically see at the iowa state fair. >> david, another twist we might see in all of this has to do with joe manchin, and he has been flirting and flirting with does he get in as an independent, what is the no labels tie here, what is this all going to mean? what do we need to know about that this morning? >> reporter: yeah, i mean, joe manchin once again sort of publicly flirting with this notion of maybe leaving the democratic party and becoming an independent. you know, joe manchin has not actually made his intentions known for 2024, not just at the presidential level, poppy, but whether or not he would run for reelection to his senate seat, which is up in west virginia, and obviously having the d for democrat in west virginia is not the best path to victory despite his past success. that might have something to do with his calculus, publicly putting out there he's attracted to the independent lane. >> kyung, there's some reference to special guests that the former president will be bringing with him. do we know who he'll be bringing to the fair? >> reporter: well, he's going to be officially bringing some of the florida representatives who have endorsed him, emphasis on florida. truly what he is also going to be doing by walking with these florida representatives is sending a signal to ron desantis, the governor of florida. certainly signaling, hey, these guys are with me, not with you, and making a very loud point as he walks through this iowa state fair with representatives from the governor's own state. so that is certainly the spectacle that we expect with trump, certainly there could be others. but we're going to be watching, especially to see what happens beyond just walking with those represent representative. >> and on the same day that governor desantis will be at the fair as well. there was no mistake in scheduling there on trump's part as well. >> they have to eat all of it. anything that they are given, they have to eat it, right, david and kyung? >> reporter: and the challenge of eating food on a stick with all of those cameras in your face, i am not jealous of them. >> thank you, guys, have fun. enjoy. >> reporter: thank you. you bet. this from the supreme court blocking a $6 billion opioid settlement that would have given immunity and civil prosecution to the family that once controlled purdue pharma, the maker of oxycontin. the court agreed to pause the bankruptcy deal that included the immunity provision. they will have arguments in december. the billionaire sackler family controlled the drug company, accusing the family and the company of fueling the opioid crisis that's killed hundreds of thousands of people. joan biskupic joins us now. really significant that the court did this? >> very much so, poppy. good morning. the court, you know, doesn't explain itself, but certainly it was convinced by the solicitor general's argument. it means that the sacklers are going to have to wait until at least probably next year, probably in the summer, to know whether they are shielded from future lawsuits. but also, poppy, the victims of purdue pharma and from the opioid crisis are going to have to wait for any kind of payments. what the solicitor general argued on behalf of the trustee for this bankruptcy that the condition of this $6 billion sackler plan, releasing them from all future liability is not allowed under the bankruptcy code, that this would be violate statutory provisions and go beyond what the code allows. it would also give, they argued, wealthy companies an ability to buy their way out of future lawsuits. now, purdue fpharma countered that this delay is only going to hurt the victims of the opioid crisis, hurt them in terms of getting the payments but we will see what court itself does. as you noted, the arguments will be in december. they're on a fairly quick briefing schedule. and as i said, a decision likely by the end of june next year. >> with this new reporting on justice clarence thomas accepting dozens of trips paid for by some billionaire friends, democrats are calling for some new ethics reforms for the court. unlikely to go anywhere if we just use past as some context. >> that's right. just yesterday, it was probably the most comprehensive report we have seen of all of these trips, you know, on private jets, this is a pro publica report you're referring to clarence thomas had benefitted from many wealthy billionaires who have themselves contributed to republican and conservative causes. let me just tell you what clarence thomas had said about that. he earlier, he didn't respond to that particular report yesterday, but he had earlie said that he had been under -- his belief was after seeking me advice from colleagues and others in the judiciary that he, this kind of personal hospitality from close personal friends, didn't have to be reported. you see his statement right there. but here's the deal, folks, even though there was some fuzziness in the code, those private jet trips that were reported yesterday, all of those were supposed to be reported fr beginning. you can see why democratic senatoe be saying that the court needs to have a stronger ethics code. it needs to be abiding by rules that are already in place. some of the things that were alleged in the report yesterday would violate what's already in law, but then stepping back more broadly, the court has resisted any kind of formal ethics code for things that are not written into law as lower court judges have, but the truth is that chief justice john roberts has been trying to get his colleagues to agree to something formal, but he does not want to do that without yunanimity, thee are too many holdouts, and yesterday's report, as much as it's gotten so much attention, and rightfully so is not going to change things either on the hill or at the supreme court. >> wow. people deserve transparency, that's for sure. joan, thank you for the reporting. >> thank you. in just a few hours, former president trump's legal team in the 2020 election case is scheduled to appear in a washington courtroom for a hearing to determine what trump can and cannot say as he awaits trial. also some of the world's top tech companies are encouraging hackers to find vulnerabilities in their artificial intelligence chat bots, part of a new competition in a hacking conference in las vegas. we'll take you there live. ree 5. plusus, switch, keep your numbe, and get up to $300 off. with verizon business. it's your business. it's your verizon. this is american infrastructure, a prime target for cyberattacks. but the same ai-powered security that protects all of google also defends theseervices for everyone who lives here. ♪ being middle classight now, it's tough making ends meet for sure. republicans in congress say if we just cut taxes even more for the biggest corporations the money will eventually someday trickle trickle down to you. right. joe biden would rather just stop those corporations from charging so damn much. capping the cost of drugs like insulin. cracking down on surprise medical bills and all those crazy junk fees. there's more work to do. tell the president to keep lowering costs for middle class families. how's the chicken?

>> that's a great question. i don't know that donald trump would abide by it. to be clear, the issue is not what donald trump can say in total about the discovery, what can he do with the discovery, the evidence and documents he's given, can he post it online, i just got a witness statement, guess who says something positive for me. i don't think donald trump will abide by this. he has a long history of that. then the question is will the prosecutor go to the judge, and say, he's violated your order. will the judge say you violated my order. she will impose restrictions, change the bail conditions. this won't happen. in an extreme scenario, you can lock the defendant up pending trial. if a defendant is out on bail as donald trump is now or on his own recognizance, can absolutely do that in a normal case. >> donald trump has said he's going to keep talking about the cases but also not just the legal side of it, politically, his rallies and his interviews are so centrally themed on these cases that it would be a huge political omission if he went to these rallies and didn't talk about this revenge. >> that's right. look, there's a way that he could do this, that wouldn't run into any kind of trouble at all, depending on what the judge says today. we know that's not donald trump's style. i mean, one of the things that's happened in the trump era, we have developed this bad habit of assuming he's not subject to the same restrictions as the rest of us. the reality is whether you happen to be a candidate or ex-president or anybody else, when you go to court, and there's a protective order in place, you have to abide by it, and we should all expect him to do exactly that. one of the most important functions in a criminal trial of the judge is to determine what is allowed in as valid evidence, and you cannot have any party, especially the defendant, go out on social media or in front of a rally, you know, on national television screaming out all kinds of information, and interpretation about evidence that may or may not ever be shown to a jury. >> speaking of evidence, james comer wants some evidence. the house oversight committee wants evidence. the american public deserves evidence. the claim is that biden, the president, benefitting from $20 million in payments, we're talking about hunter and business dealings. jake did a good job of saying where's the evidence, now this committee doesn't think they need direct evidence. it's enough to basically show, i guess, that hunter bide got paid to be on a board of a company, which is normal. i'm not saying the way they did that with burisma and ukraine and his position is normal, i'm saying people get paid for board work. >> james comer and senator chuck grassley say in may, we have this allegation that joe biden took a bribe. $5 million was the allegation. they spent three months and no new evidence in support of that emerges. james comer has used his position as chair of the oversight committee, talking about how joe biden is corrupt. we see the business partner, hunter biden coming to provide this system testimony and what say. joe biden shortly after the death of his son would call his other son and hunter biden put him on speakerphone. he got an e-mail from hunter biden which he said, we can give the impression that my dad is going to do stuff, but he's not going to do anything for us. joe biden was never involved in the business. i never saw evidence of a bribe, but you never hear about that stuff. there isn't this evidence, but they keep trying to manufacture a sense of a case. >> back up an impeachment proceeding? >> presumably. think about what donald trump did in 2019. he wanted president zelenskyy of ukraine to just announce an investigation into joe biden's work in ukraine. james comer stepped up and has done that. >> if we think back to 2015, and then kevin mccarthy, before the speakership, who said people thought that hillary clinton was going to run away with the presidency, look what we did, we created this benghazi special committee and look at her numbers now. is that a cynical connection? >> it's almost the same playbook, the difference is this is purely protective. in order to enable donald trump to say, and at some point, politically he's begun to say thrk this, look, he's got problems too. he's involved in untoward activity as well. the problem is when you look at it and after reading phillip's piece, i looked at documents of the committee, 20 minutes of my life i'll nevaer get back. they're assuming a conspiracy rather than proving it. hunter biden has, you know, breakfast, he has eggs and bacon for breakfast, they write that out, and put in the biden family had eggs and bacon for breakfast. in every single case, everything that he does, they say the biden family, the biden family, none of it is proved. >> credit for james comer for coming on and doing the interview on cnn with jake. an important conversation. i want to play part of what he told jake in control room, they're being blocked by the feds, the irs, et cetera. here it is. >> this is why we're investigating, and it's difficult, jake, it's very difficult. the biden attorneys are obstructing, they're intimidating witnesses, the doj will not cooperate with us, the fbi will not cooperate with us, the irs will not cooperate with us. >> fact check that for us. they wanted this 1023 form about what a witness said. the irs eventually gave them one. have all of these entities not been playing ball at all, what are they required to do? >> doj is not going to just open up its files. the irs is not just going to open up its files to anyone, including to congress. doj has ongoing sensitive investigations. irs has limits on what they can put out there, by the way, on the topic of congressional subpoenas, james comer is feeling the frustration democrats felt with the january 6th committee which is that congressional subpoenas are often disregarded, often without consequence. and by the way, let's remember, jim jordan, kevin mccarthy, and others subpoenaed by the january 6th committee, blew it off. knock happened. it's a little bit of what goes around comes around here. >> gentlemen, thank you very much. a sheriffs deputy in colorado is going beyond the call of duty to help a family in need when he learns two young boys are in desperate need of food. >> i just knew there was something i could do, and i didn't want to leave having that feeling later, knowing that in that situation, i could do more. four. supreme meatats. six. the bossss. fifteen. titan turkey. ninety-nine. grand slam ham. i'm gonna need twenty-three of those,e, it's my turn to bring the snacks..
