[ applause ] in the nation 's capital, a the steps of the u.s. capitol, president biden there along with first lady jill biden. they're at the national peace fallen soldiers service. the president there expressing how he can relate to loss. quoting him now, he said it's like losing a piece of your soul. he said it's hard. and he admires the courage of the family members for being there. the family members of the 491 men and women whose lives were lost in the line of duty in the years of 2019 and 2020. and it this is what this ceremony is all about, as they pin a flower to the 14 there honoring the lives lost in the line of duty. he also injected, of course, some policy talk from tackling the gun violence to reenvesting in the area of policing. the president reasserts his commitment to police across the nation. cnn's joe johns is at the white house for us. joe, give us an idea, the sin nap synopsis, the real goal that the president has honoring the lives lost. >> reporter: well, you know, grief has been called joe biden's superpower because he has such experience with it not only from the death of his son beau and also his daughter and his wife back in 1972. they die in an automobile accident. i think i picked up the same quote that you did in that vain, it's like losing a piece of your soul. he said, also i think important to mention that he did talk just a bit about january 6th up on capitol hill, where a number of police officers were injured and died as a result of the riot there. remembering their memory. and i talked a bit about gun violence reform. and it was not an overly political speech, or a speech tied to policy as much as it could have been. i think the other thing, you have to say about joe biden is he is a president who tries very hard to relate to people in circumstances like this. of course, this a situation where the audience is the members of the family, the survivors of people who were in law enforcement and died over the last year. so a brief speech for joe biden but certainly poignant, given his own personal experience with grief, fred. >> exactly, joe. and it's notable that the president said, you know, it's particularly appropriate today, nine months ago. your fellow brothers and sisters, you know, thwarted attacks on the values. on the nation's value, making reference, of course, to what took place, january 6th. and he said, in addition, he had no hesitation in signing the congressional gold medal that will be bestowed on the metropolitan police department and u.s. capitol police. 150 officers injured. five who lost their lives in the attack. and the aftermath. >> reporter: right. a day that will certainly live in history. and up on capitol hill, the repercussions from it are still being felt, very much so, given the fact that these investigations continue. an officer just very recently charged essentially for trying to help someone who had posted a bunch of stuff on social media relating to this -- this day. and his own personal involvement in it. so, america continues to wrestle with what happened on that day, rebellion, essentially, against the united states. and appropriate also to remember those officers who died or were injured as a result of the riot, fred. >> that's right. all right, joe johns at the white house, thank you so much. appreciate it. we'll check back with you today. meantime, today's event coming as the presidentfrantically searching for a way to move his stalled agenda through congress. daniella diaz is there. president has a lot to do in terms of influencing things and negotiating with these members of congress who have yet to solidify a plan that is ready to vote on. >> reporter: that's right, fred, and they're bickering with each other, openly, publicly. you know, yesterday, senator bernie sanders published an op-ed in senator joe manchin's biggest daily newspaper in west virginia where he touted the $3.5 trillion bill. saying that his constituents, manchin's constituents need to get behind it. this is what he said -- what i'm about to read is manchin's response to senator bernie sanders put this up. this isn't the first time that an out-of-stater has tried to tell west vanirginians what is good for them despite having no relationship to our state. congress should proceed with caution on any additional spending. and i will not vote for reckless expansion of government programs. no op-ed from a self-declared independent socialist is going to change that. these are what was written in the west virginia newspaper. the problem here, moderates and progressives cannot agree on a top line number for this massive economic bill president joe biden has promised earns would pass. this will expand the nation's safety net. and progressives want it and say they pared it down to 3.5. senator joe manchin and senator kyrsten sinema want to bring it down. i also want to talk about the climate bill, that joe manchin does not agree with. he does not agree with a bill that would slash greenhouse gases that half by 2030. and this was the measure of the bill and democrats were pushing for this likely will be dropped in the legislation because senator joe manchin is not behind. the bottom line, moderates and progressives are going to work hard the next couple weeks. they said they have, they've been in discussion. the self-imposed deadline that house speaker nancy pelosi set for october 31st, coming up. that's when they're trying to passion the economic bill and separate bipartisan infrastructure bill that needs to pass the house before it gets to joe biden's desk. so a lot of work to be done here in biden's stalled agenda to try to pass it. >> big work in progress. daniella diaz thank you so much on capitol hill. joining me now is katharine hayhoe heave conservconservists auth or of "saving us." thank you for being here. >> thank you for having me. >> you know more than most, what is your reaction to the considerations that possibly on the chopping block would be climate crisis-related provisions? >> re >> well, clearly, we're in a tight spot where some things might have to be dropped from the bill but it can't be climate solutions because this is the best chance in a decade to respond to scale with the impacts of climate change right here, right now, in the united states. and to bring to the table at the glasgow meeting coming up in a few weeks a contribution to that global potluck that is not full of hot air. >> so the president said recently, while he wasn't specific about what cuts would come, i mean, he -- he acknowledged that there would be cuts that are likely to happen. and that perhaps some of those things that would be cut would likely get another chance at another time. is that a concession enough for you, particularly if it ends up being climate-related provisions? >> well, as a climate scientist, i can say this, every year matters. every extra amount of carbon we introduce, through lack of policies across the country and around the world, every kind of carbon carries with it an additional cost. it's like there's no magic number of cigarettes we can smoke before we develop lung disease or cancer. and we know the more we smoke, the greater the ricsk. there is something attached to it every day. >> in fact, this was the president yesterday. listen. >> when i think climate, i think jobs, good paying union jobs. this is an opportunity. we're the only country in the world that has consistently turned difficulty into opportunity. we have a chance to not only make this world more livable, but to actually create greater opportunity for people. making landmark investments in public transit and rail. increasing efficiency, reducing emissions. you know, there's millions of kids getting on diesel school buses and inhaling air, getting asthma, they should be electric buses. >> addressing the economic benefits, is that the approach that perhaps might make any climate change provisions more p pala palatable. >> they ask the question how can we afford to ask, but that's the wrong question. the question is how can we not? we cannot survive without the resources this planet provides. we cannot float around in outer space clutching our economy to our bosom. we need this planet. the planet doesn't need us. so that's why fixing climate change isn't about saving the planet. it is literally about saving us. we see the impacts here and today, and it makes every kind of financial sense, as well as ethical sense to do everything we can as much as possible, as soon as possible. >> well, talk to me about what you believe might be the struggle about trying to get people to talk more openly, more graphically, about climate change. and expressing whether they have a good grasp of just how serious the matters are. >> we are not talking about climate change. a recent survey showed that 14% of us talked about it frequently. 34% of us hear somebody else talk about it, or talk about it ourselves occasionally. why does that matter? because if you don't talk about it, why would we care? if we don't care, why would we ever want to do anything about it. the most important thing we as kids can start to do is talk about it. but not unloading more scary scientific facts but talking about what is affecting what is nearest and dearest to our hearts. place we live, the home, the air that we're breathing. the activities that we enjoy doing. our businesses, our economy, our national security. and talking about what real solutions look like. what clean energy looks like, what jobs look like. what clean sky we saw turn the pandemic, what building back better clearly looks like for the crisis and recovering from the pandemic. we have to do it all together. and we can. that's what this bill is all about. >> kathryn hayhoe in plain speak. i appreciate your time and energy. >> thank you. president clinton remains hospitalized this

off. and we're talking a possible completion of that in the next day or so. all tests, though, point him trending in the right direction. and we did, in the last hour and so did see his wife and

fda's independent panel of vaccine advisers just green lit a booster dose of johnson & johnson's vaccine. the move comes as new data from the cdc has a dire warning for unvaccinated adults. the risk of dying from covid-19 is 11 times higher than for those who are not vaccinated. those who are fully vaccinated, rather. cnn's nick watt has more. >> reporter: those fda advisers gave their thumbs up for a second shot of johnson & johnson. at least a couple months after the first. now, of course, the cdc still needs to sign off on that. now, in general, the numbers in this pandemic are going in the right direction. but, still, new guidance from the cdc, for the upcoming holiday season, probably some of the news you didn't want to hear, but apparently outdoor gatherings are still best. if you're indoors, still wear a mask. but top of the list, just get vaccinated. now, some good news for the u.s. tourist sector from november 8th, all double-vaccinated forners will be allowed into this country. and while the arguments continue over vaccine mandates here in the u.s., some news from italy, from friday, every worker is going to have what they call a green pass, which is proof of vaccination, or proof of recent recovery from covid-19. >> nick watt, thanks so much for that. let's now talk more about all of this. let's bring in dr. jane morgan. she's a card nothiiologist of t piedmont task force. so good to see you, dr. morgan. now three vaccines now with authorizations for booster shots. what are you telling patients about whether they should get one or not if they're eligible, of course? >> right, so if you're eligible for these messenger vaccines, thanks for having me today, fred. for the pfizer and moderna vaccine, it's pretty clear what the advice is. for particular groups, 65 and older, people who are health care workers, institutionalized situations and those at severe risk of developing complications and disease if you were to contract covid-19. and that includes pregnant women. pregnancy is included in that group of people who are considered to be at high rick for severe disease. and then with the johnson & johnson, we see that with that second dose, we get that increase in that immunity that we are looking for. and we see that both moderna and johnson & johnson were approved to move forward. >> so, they all had relatively impressive efficacy rates. johnson & johnson had one at 72% versus moderna and sizer, 94 and 95%. now, to understand that, with a booster, johnson & johnson is 100% with efficacy. now, that's pretty impressive. and if that's the case, you know, many people are kind of wondering why didn't they just use two dose from the beginning. >> that's such a great question, fred. and one of the reasons is that, you know, the bar for vaccinations is at least over 50% for the fda. so, in the single dose formation, they reached 72% efficacy. when we look at the data submitted to the fda and the briefing documents for moderna and pfizer, with one dose they reached about 35 to 45%. it was the second dose that got them to 94 or 95%. so it's the same two-dose regiment as moderna and pfizer. >> even though one dose is appealing to a lot of people, even though the efficacy rate is a little low, it does inspire more people who actually get vaccinated? >> no, absolutely. we certainly have groups that absolutely benefit from this johnson & johnson vaccine. and we want to have always remember that. and also, we want to know that it was 100% protected against death and hospitalization. those were the main end points. although there's slightly less efficacy, with regard to symptomatic infections, the main end points of complications and death are very real. we see with the delta variant, all of the vaccines were underchallenged. and the johnson & johnson vaccine probably more so than moderna and pfizer. >> what about on the mixing and matching of doses from different vaccines. the fda isn't saying anything about it officially, but studies outside of the u.s. seem to indicate it's effective to do so. >> right. we see the studies and we have to remember that these studies are increased and their not peer reviewed. that being said what is demonstrated in the studies is that it does appear to be safe to mix and match these vaccines that include johnson & johnson with moderna and pfizer. and we do see these responses, these different responses, after we get these additional doses of moderna, pfizer and johnson & johnson, with moderna seeming to perform somewhat better than pfizer. >> fda says it's also reviewing moderna's application for children ages 12 to 17, as expeditiously as possible. pfizer already has authorization for that age group. are there any lingering concerns out there for any potential side effects for that age group? >> i think when we think about younger and younger demographic, as we do these bridging-down studies, pfizer and moderna have gotten it absolutely right that they must do a dose finding phase. because as we get younger, our immune systems are less mature. so, we see that pfizer reduced its dose by two-thirds. and we see that moderna halved its dose. we may see that, as we get to younger and younger demographics, lower doses as well. absolutely, one of the tenets of medicine, you always want to give the least amount of medication for the maximal effect. we will look for that in children as well. >> dr. jane morgan, always good to see you, be well. >> thanks, great to see you as well. all right. in chicago now, a showdown over vaccine mandates between the city's police union and mayor. the standoff has escalated to the point where up to half of the city's officers could be placed on unpaid leave, over a mandate for them to disclose their vaccination status. chicago mayor lori lightfoot blasted the union president yesterday saying he was trying to induce an insurrection. cnn's omar jimenez is in chicago with the latest. >> reporter: well, fred, bottom line, police officers are going to be on the job this weekend, and as expected by the chicago police department and the mayor of chicago. this comes on the tail end of a week where we've been hearing from the head of the chicago police union urging chicago police officers not to comply with the city's vaccine policy which, of course, is at the center of all of this. the vaccine policy is by october 15th, which was yesterday at this point, you have to disclose your vaccination status. and if you don't, you get placed on no pay status. basically unpaid leave. you have to be vaccinated. and if you're not, you choose to go into a twice weekly testing option. in the midst of all of this, there, of course, has been a lot of back and forth between the city and police union. the city miled legal paperwork, asking a judge to stop the head of the police union, from urging officers not to comply with this policy. well, they got their wish, as the judge issued late friday, a temporary restraining order saying that the police union cannot publicly urge officers not to comply. the union filed their own paperwork urging that the city, the mayor and the chicago police superintendent acted union art unilaterally and it went against policy. of course, the city feels differently. and when the mayor was asked whether she was worried to potential up to 50% of the police force not being compliant, she said, no, she expected people to be here this weekend. now, it's going to take a few days to tabulate who is in compliance and who isn't. the city has acknowledged that. it won't be until then that any next-step measures will be taken with regards to no pay status. and then moving forward, asked on contingency plans, the mayor did say there are state police resources that they could lean into if needed but she doesn't expect that at this point. fred. >> omar jimenez, thank you for that. coming up, the january 6th committee has questions

and is the first police officer on duty on capitol hill on january 6th charged with allegedly attempting to help a rioter. according to the indictment, riley told a contact online to remove posts showing the person was in the capitol building that day. he has not yet entered any plea and has been placed on administrative leave. cnn's katelyn polantz joining me now. what more are you learning? >> well, fred, this is an unusual case among the hundreds we've seen thus far in the capitol riots. that's because michael riley is a member of the capitol u.s. police force. and not only that, he was working on capitol hill on january 6th. he was on his radio, hearing other members of the force taking on the siege at the rioters at the capitol and he was responding to a bomb threat on capitol hill. now, what happened to arise to these charges, the next day on facebook, michael riley allegedly reached out to a contact of his, who he saw posting on social media, selfies of the person being inside the capitol. and riley then wrote to the person in a direct message on facebook. i'm a capitol police officer who agrees with your political stance. take down the part about being in the building. they are currently investigating and everyone who whats in the building is going to be charged. he did continue to give the person warnings to take down social media posts and that person was arrested, ultimately, and pleaded guilty to being inside the capitol that day. now, riley is also charged with deleting some of his own facebook messages after the person he was in contact with was charged. and, fred, he's now on leave from the force as you mentioned, and he is going to be fighting these charges in court. that's what his attorney told us yesterday. >> and katelyn, is there any feeling or suspicion that there could be other officers facing charges? >> well, fred, that's a good question. this right now, appears to be a very isolated case where investigators were scouring social media, talking to people they were charging in the riot and did come upon this. that's what this looks like in the indictment, but we do know there were many members the american military and law enforcement fire departments who were taking part in the riot that day. >> katelyn polantz, thank you so much in washington. right now, a manhunt is under way for a suspect who shot and killed a deputy and injured two others outside a sports bar in houston, texas. several law enforcement agencies in the area came together earlier today to escort the fallen deputy's body to the local medical examiner's office. houston police say the deputies were ambushed while working a police-related side job. a person of interest is in custody. but it's unclear whether it is the suspected shooter. cnn's jean casarez joins me now. jean what information are you learning? >> reporter: well, we are learning right now and this could become an important fact that the officers that were involved were in full uniform. and this happened about 2:15 this morning in houston, at a sports bar. the officers heard something was happening in the parking lot, so two of the deputies came out to investigate. they found who they believed was one of the people responsible, they had him on the ground. and let's listen to the houston constable tells us the rest of the story. >> our deputies went out to confront a suspect. while they were trying to make an arrest of that suspect, they had him on the ground. and a second suspect came out of nowhere with a rifle and began to basically shoot our deputies. a third deputy that was here, heard this, went out to the location, and he ended up getting shot, too. >> reporter: now, when they say that that person came out of nowhere, what houston police is now saying that someone came from behind a car with a rifle. and started to shoot, as those officers were on the ground. one was shot in the back. he is in surgery today. the other one succumbed to his wounds. and the third deputy came out when he heard everything, and he was shot in the leg. has multiple broken bones in his leg. and it is very ironic, because the police chief from houston is actually in washington, d.c., where we just highlighted minutes ago, president biden talking about and giving his remarks on the fallen officers of this country. the police chief of houston lighting a memorial for the fallen officers of houston. and now his deputies, his constables in houston, having to deal with this ironically, on the very same day. >> my goodness. jean casarez, thank
