it is the top of the hour. i am brianna keilar. in just hours, president trump and democratic nominee, former vice president joe biden will share a stage one last time in the closing days before the election. the president needs to convince americans he deserves another four years. biden needs to maintain the campaign's momentum in the final days. the election commission is desperately trying to turn the page from the first matchup with new rules in place. arlette, we are wondering what we can expect from each candidate when they take the

stage? >> reporter: they're certainly hoping the debate may play out less chaotically than the first, but for president trump, he's hoping to change the trajectory of the race, while joe biden is simply trying to protect his lead. for the format, the debate commission changed the way that the microphones are working at the start of each segment. the candidates will each have two minutes where they can speak without the other candidate's microphone on. this is to try to help avoid some of the interruptions that we saw play out in cleveland just a few weeks ago. after each of the candidates gets their opening segment, during those two-minute segments during each section, they can move on to an open period of discussion, where they can both have their microphones on and proceed with talking. there will be six segments over the course of this debate. i want to run you through those

topics -- rain in america, climate change, national security and leadership and more. this will be a 90-minute debate. something different, is there will be plexiglas barriers erected between the two candidates on stage. that's something we saw during the vice presidential debate between kamala harris and mike pence. today they are instituting that once again here at the presidential debate after the debate commission consulted with their medical advisers. we have learned that joe biden tested negative for coronavirus this morning. we haven't heard if president trump has undergone a similar test before he proceeds with this debate, but this debate is essential going to be voters' last chance to size up the two candidates on that stage one on one, face-to-face together. we're just 12 days out. there's still a number of undecided voters tuning into this debate to see if it can help make up their minds about

who will be the next president. arlette saenz, thank you. ahead of tonight's matchup we're seeing the president return to one of his go-to lines. >> let me ask you what you think the biggest domestic priority is for you right now. >> well, ultimately -- let me -- it was happening. we created the greatest economy in the history of our economy. the other side -- >> you know that's not true. >> it's totally true. >> no. >> that is not true. one topic that biden will likely answer for is expanding the supreme court. here is how biden is now addressing that question. >> if elected, what i will do is put together a national commission, a bipartisan commission of scholars, constitutional scholars, democrats, republicans, liberate, conservatives, and i will ask them to over 180 days come back to we some

recommendations as to how as to reform the court system, because it's getting out of whack, the way it's being handled. it's not about court packing. there's a number of other things that scholars have debated. i've looked to see what recommendations that commission might make. >> cnn political director david chalian is joining mess to discuss. this is the last matchup. what are you watching for? >> the second and final matchup. the first thing i'm looking for is donald trump's approach. we've observed him long enough. we don't expect him to change all of a sudden, but what version of himself does he bring to this debate stage? much like the first performance where he was consequence taply interrupting, creating chaos? none of his advisers did not want that. it did not go well for him. in a remarkably stable race,

there was a noticeable dip after that first debate. yet there are some signals that that may be the road he's going down, or does he lean into more advantages on the economy where voters see him better than joe biden on that score. does he try to seize this opportunity, as arlette was saying to change the dynamic? i think that is one key thing to watch. for biden's part, brianna, his defense. that i think is going to define his performance tonight. we know biden would like to stay above the fray as much as possible. of course, like any front-runner, do no harm. if donald trump is throwing things at him about hunter biden, his son, his big dealings, how joe biden responds to that, does he get rattled? is he able to simply ignore it and move ahead with his own strategy, i think will be the

defining aspect as to how biden's performance is perceived tonight. my final thing i'm watching is that muted moment. arlette took you through the rules and there's a new enforcement mechanism where, if you're not speaking in that first chunk where you have two minutes to address it, if you're the opponent not speaking, your microphone is muted. is donald trump going to obey that? is he going to try to interrupt and speak over his muted microphone? and still try to throw joe biden off his game? or does that enforcement mechanism actually bring more order to the debate stage tonight than existed in cleveland last month? that's the third item i'm on the lookout for tonight. >> yeah. i'm very curious about that mute function. we'll see how it goes. david, we'll be watching. thank you so much. >> thanks, brianna. more than 1,000 coronavirus

deaths, we hit that milestone yesterday, the highest daily toll in more than a month. this time experts say the worst is yet to come. there are 31 states reporting more covid cases than last week. there's only one moving in the right direction, hawaii. we haven't seen this level of 60,000 since the first week of august. severity states hit record highs on hospitalizations, including iowa, kentucky, ohio, oklahoma, south dakota, as well as utah. you can take a look at the u.s. coronavirus death toll on the right side of your screen, more than 222,000 lost. a new study found that most of those deaths were unavoidable.

elizabeth cohen jones me now. the death toll could be between -- not 222,577 if there had been an adequate government response, elizabeth. >> that's right. just to try to describe how inadequate the government response has been, it is tough. we're going to try to boil it down to a couple points. again, this report from columbia university saying there could have been tens of thousands fewer deaths if different things had been done by the federal government. let's look at those. they said there was insufficient testing, lack of a national mask guidance. the trump administration young played the pandemic and mocked masks. masks saves lives, and mocking them does not help. pakistan, hon during rattle and malaysia had more successful

responses, and it was pointed out that trump advocated for solutions that didn't work, for example, hydroxychloroquine, so that also added to the death toll. brianna? >> tell us about the cdc revision on was considered close contact with someone infected with coronavirus. what is the change here? and why the change? >> the cdc has been saying for month a contact means -- when we say you've had close contact with someone with covid. we mean have you been within six feet of them for 15 minutes or more. now the cdc is making it clear it doesn't have to be 15 minutes consecuti consecutive. it can be cumulative. the state of vermont noticed for their corrections officers that they were at risk for getting covid even when they weren't within 15 minutes of someone all at one time. it could just be bits and pieces

pug together. it makes sense. it's the amount of time put together that you are near someone with covid the chances that they will get you sick. >> and they're investigating the way to shorten the time for school kids. >> this is something they're looking into that they haven't actually done yet. i asked dr. robert redfield about this yesterday. he said, look, we're looking at the science. this pandemic is relatively new. we were saying people need to quarantined for 14 days if they've had close contact, on if they've had covid themselves, they need to be isolated maybe 12 is okay, there are various studies, and dr. redfield said they're looking at the studies. >> elizabeth, great to see you. thank you so much. >> thank you. the cdc records that about two 1/3 of the deaths were from

covid-19. jacqueline howard has more. >> some experts say the other deaths which represent about 100,000 lives lost might be deaths of despair. the term deaths of despair refers to deaths caused by suici suicide, alcohol or drug use. here's what dr. scott gottlieb has said about this, especially when it comes to younger adults. have a listen. >> i would suspect a good portion of the deaths were due to despair or other reasons. we've seen a spike of overdoses. >> one of the biggers jumps have been with adults 25 to 44. thank you. we'll hear from the top health official in mississippi, who says the spread in his state can

be traced to people not wearing masks. and intimidating e-mails sent to voters. one topic that should come up tonight -- health care. we'll roll the tate about president's nonexistent plan to replace obamacare. ♪ we'd be closer to the twins. change in plans. at fidelity, a change in plans is always part of the plan.

of course. podcasts. originals. bestsellers. future bestsellers. sleep stories. mal... hey, no! roxy! audiobooks, podcasts, audible originals, all in one place.

tonight, in his final debate with joe biden before the election, the president will likely be asked about his plan to replace obamacare, the law he's trying to kill, and for which he does not have a replacement. with 12 days to go and millions of americans have been already voted, still no comprehensive plan to protect americans with preexisting conditions, no plan

that could be sent to congress to become law, no plan despite countless timetables and missed deadlines. >> i will ask congress to convene a special session so we can repeal and replace. it would be such an honor for moe, and for everybody in this country. as soon as our secretary is approved and gets into the office, we'll be filing a plan. we have a really terrific i believe health care plan coming out. we're going to have a health care plan that would be second to none. it's going to be great. we have two plans coming out. coming out in a very short period of time. >> we're going to come up with a health care plan. we're not going to vote on it until after the election. >> the plan is coming out in the next four weeks. >> produce phenomenal health care. we will be have the concept.

can. >> can you tell us what the plan is in. >> we'll announce it in about two months. >> it will be if we take back the house -- >> we're signing a health care plan within two weeks, and full and complete health care plan. >> we'll be doing a health care plan, a very inclusive health care plan. i'll be signing it very soon. it might be sunday, but it's going to be very soon. >> we're going to be introducing a tremendous health care plan sometime prior -- hopefully prior to the end of the month. it's just about completed now. >> we'll be doing a health care plan -- i before viewed you in june, you said the health care plan would come in two weeks, you told chris wallace this summer it was in two weeks. >> i have it all ready. i have it all ready. as americans vote, tonight would be a good night to reveal the long-promised details of this plan.

if he waits another two weeks, polls will be closed, right? still ahead, we'll break down the electoral map to see what each candidate has to do to win. plus e-mails warning to vote for trump or else? now the top security officials say iran and russia are behind these schemes. look, this isn't my first rodeo

with just 12 days to go until the election we're learning from the top national security officials that iran and russia are actively interfering in the 2020 election. director of national intelligence john ratcliffe says both countries have obtained voters registration with iran posing as the far-right group proud boys and sending intimidating e-mails. one in part says you will vote for trump or we will come after you. it concludes, i would take this seriously if i were you. >> the timing has raced questions. the briefing was hastily arranged, and delivered minutes after president obama offered a strong rebuke against president trump. anthony, there was a source who told cnn that the government assesses some of the data that the iranians obtained came from

vendor and state systems, not publicly available voters registration information, so that's alarming. how did they get it? does that mean this information is vulnerable to other attacks? >> of course. let's take a step back, a month ago, many americans had never even heard of the proud boys. as of yesterday, many received a threatening e-mail from this group telling them they had to vote for donald trump or else. this is clearly escalating behavior. as we were briefed yesterday, iran and russia have now taken this bullying tactic and brought it into the homes of americans. this is no longer just targeting state infrastructure like they did in 2016. they have escalated the fight, brought it into the kitchens of americans across the country. we need to appreciate what that

means. >> i said to listen to something the dni said last night. >> we have already seen iran spe sending spoofed e-mails. >> the e-mails make it clear they want people voting for trump. he's saying this was a coordinated ever to hurt trump. what do you say to them? >> as a former fbi special agent, it's very troubling for me to see that. i watched the press briefing, i looked on stage and saw no special investigators on stage. i saw all trump political appointees. it broke my heart to see them stand before the fbi seal and make that statement.

you can interpret the statement and e-mail any way you want, really. that statement the dni made, it just wasn't necessary, and it took a very important message, right? a very important message about americans being targeted. americans now facing this fight in their homes, in their kitchening, and it put a political spin on it. it just want necessary, right? it's super frustrating it happened in the fbi building, in front of an fbi seal, with no investigators up on stage, just political appointees. there's more to be done here, right? it's a threatening e-mail saying you must vote for donald trump or else, but what are we going to do about it? the government said they're aware of it, but didn't say what they're going to do about it. so what's next?

i hope to have more than just a monitoring squad. i would like to see some action come out of this. >> i wonder if the dni has been co-opted by the political apparatus. he also offered statistics about iranian interference, but didn't provide the same level of detail when it came to the russian interference. >> i had the same reaction to the briefing. there's no other way to interpret these activities other than escalateory. they were done strait infrastructure. the fact they pulled this data, whether stolen illegally from compromised infrastructure, or obtained it legally from paying for it, they still took these steps. they did it in the public's eye. they did it in plain sight. they weren't secretive about it

at all. to my understanding they also used a foreign infrastructure in which to launch these e-mails that landed in the homes of american citizens. i just think that this is clearly escalating behavior and i would like to see some sort of response activities. remember, in 2016 when this happened, it was a difficult subject, it was a very sensitive subject, yes. the administration was slow. i am very happy to see the press briefing last night that the administration is working quickly to inform american citizens. what are they doing about it? christopher wray saying you should have confidence in voting, that's not the problem. it's not a tactical problem, okay? we really need to help americans understand this is a massive, real, right, misinformation campaign. russia and iran are behind this.

>> anthony ferrante, thank you. we appreciate it. >> thank you. can president obama move the needle for joe biden? >> tweeting at the television doesn't fix things. making stuff up doesn't make people's lives better. you've got to have a plan. you've got to put in the work.

all of them carried by president trump last name. right now biden is -- and wisconsin to some democrats with 2016. what if this happens -- the topups, and these come back into play, and then you're in a death match, right? , and other dumbing come back to where they are right now, and they say, you know what? look at this. jibe join and -- take on -- in september 1st, the democrats are outspending the republicans. look at these battleground -- he's in play everywhere. slightly -- slightly in florida, likely in north carolina, iowa,

ohio, texas down four, so -- and they say, wait a minute, what if they had -- what if join yoib could do this? including this. is that going to happen? probably not, but is it because of the money, there's a possible that biden could -- some democrats are saying we could get texas. why is it important to compete? senate races, senate races. senate races, senate races, so democrats are looking at this map saying it's possible, it's possible we could have a very big win. >> democrats are hoping to turn the electoral map blue by deployed one of their big weapons -- president obama. he made his first appearance, and showed no mercy to his successor in the white house.

>> just yesterday, when asked if he would do anything differently trump said, not much. really? not much? nothing you could have think of that could have help some people keep their loved ones alive? and with joe and kamala at the helm, you won't have to think about the crazy things they said every day. that's worth a lot. you might be able to have a thanksgiving dinner without having an argument. you'll be able to go about your lives, know that the president is not going to retweet conspiracy theories. we're not going to have a president that guess out of hi way to support anyone who doesn't support him or threaten them with jail. >> i want to bring in cnn political commentator errol lewis, who is the host of the podcast, "you decide."

what do you make of the former president's decision to stay off the trail until now? >> well, he tends to bide his time. in 2016 he did the same think, he tries to hoard his political capital and deploy it at the last minute. there's a lot of people who wish he would get out earlier, but that's been through his political career. now that he's out, though, he's occupying an interesting sweet spot between the bernie sanders wing of the party that says the whole sim has to change, and the careful joe biden argument that's designed to try to reach across the aisle. you have this sweet spot in the middle for people who don't like to vote republican, but they also don't necessarily want to blow up the whole system. that's where barack obama i think is at his most effective. i heard kind of that walking down the middle of walking done the collision in yesterday's speech, breaux ana. >> so maybe more traditional

democrats he's appealing to. donald trump has tweeted out about this, saying this works to his favor, that the president obama being out there is something that benefits him. what do you think about that? >> well, look, donald trump's strategy has been to mobilize, energize, aggravate and enrage his base. nothing enrages them about the sight of barack obama. so to a limited extent, that's probably true. it might even bring out more donald trump voters than before. the only problem with the strategy is that's what he's been doing all along and the polls suggest it's not working. however they might want to hate on hillary clinton and barack obama and everything else, they also have to deal with real-world problems, like mass hunger, unemployment, long, long lines of people waiting to get food. the ever-present danger of the

covid. you know, we've got a reality show president trying to return this into a reality show showdown, but i don't know that he's gotten those people on his side. >> i'm wondering, will tonight be as nuts as it was last time? >> i only thing i wonder if he'll interrupt it just like the "60 minutes" binterview. when everybody gets to thes except floating around the web, you can see he's got an answer for everything. it's just a careful distribution of fault to absolutely everyone else. the handling of the coronavirus not his fault. the entry into the united states not his fault. the failure to come up with protective equipment, not his fault.

the rising statistics, not his fault. he just goes on and on and on. the economy, not hi fault. he has a way to blame everybody, but after a while he gets visibly angry in that interview. when reality starts to set in and if joe biden is a competent debater tonight, he'll bring home this point. the president thinking beshd all by talking about hunter biden and some stolen laptop when we're closing in on a quarter of a million dead and a economy in at that time e tatters. >> errol, i know you'll be watching, as will i. thank you. >> thanks. mississippi's top health officer will join me next. he says white people refusing to wear masks are to blame for the increase in cases in his state. southwest is starting to

sell every seat in its flights, as airlines report staggering losses. can saving the planet be my job? how can i make change in my community? how can i become a congresswoman? what do i need to study to become a senator? could i change things more at the state level or the federal level? do i have to be mayor before i become governor? why aren't there more women in government?

change begins with a question. so citi foundation is supporting girl scouts as they empower young leaders through civic education to help create a better tomorrow.

who's sujoe biden.rop 15?

biden says, "every kid deserves a quality education and every family deserves to live in a safe, healthy community. that's why i support prop. 15." vote yes. schools and communities first is responsible for the contents of this ad. traffic and air pollution will be even worse after the pandemic. that's why we support measure rr to keep caltrain running. which is at risk of shutdown because of the crisis. to keep millions of cars off our roads, to reduce air pollution and fight climate change. and measure rr helps essential workers like me get to work and keep our communities healthy. relieve traffic. reduce pollution. rescue caltrain. [all] yes on measure rr. who'sgovernor gavin newsom. the governor says prop 15 is, "fair, phased-in, and long overdue reform", that "will exempt small businesses and residential property owners." join governor newsom. vote yes on 15.

the u.s. airline industry posting record losses, pleading with the trump administration for a coronavirus testing strategy. airline trade groups and unions are telling the federal government travelers need a way around pandemic quarantines that are, quote, decimating the industries. that's where we begin our look at coronavirus headlines across the country. southwest airlines says it's done with the policy it put in place because of the pandemic. it will soon start selling every seat on board its flights. southwest just posted record financial losses. it says it is done capping capacity on the flights starting decent 1st, and it insists that science is on its side. that makes delta the last of the four big airlines still not

selling every seat. illinois is among the states leading the nation in increasing cases. starting friday, gatherings will be limited to 25 people or less. indoor dining and bar service will also be banned. the governor has given the green light to the illinois state police to have the ability to issue citations if people aren't following the guidelines. also, the state has the authority to pull someone's liquor license if they aren't following the rules. after a wave of infections at california's san quentin prison, a state 'peals court has ruled that they have to release or transfer half the inmates. san quentin is the state's oldest prison and houses the state's death row for male

inmates. the ruling comes after 75% of the inmates came down with the covid. officials that managed the prison say they disagree with the rulings and will determine the next steps. in the beginning coronavirus hot spots were a big pop ulutz city sisters, the top health officer in mississippi says while more people of color fell ill, it's the white maskless residents to brame. infections in that demographic are very much on the rise now. i want to speak with dr. thomas dobbs. you're seeing some patterns certainty worth talking about here. we know that people of color versus disproportionally hit,

and disproportionally represent essential workers, but now you're seeing white mississippians catch >> we've seen a pretty remarkable shift early on. african-americans accounted for basically two-thirds or 60% or more of cases and deaths. over the summer and into the fall we've seen that shift basically upside down. now over 60% of new cases are in caucasians and the deaths are mirroring that also. it's really something we've got to watch closely because we've been working hard to try to work on social distancing and masking. it may well be we found a receptive audience in the african-american community, maybe because they were hit so hard and personal experience. we're not having the success we've seen with other segment of the population. >> explain to us this disparity when it comes to behavior that

you're seeing between these racial groups. how are they differing right now? >> you know, anecdotally and looking how the schools are operating, we are seeing a lot more enthusiastic compliance with our recommendations as far as masking and public social distancing small groups. nothing is perfect, but the message seems to have hit fertile ground if the black community. we have other areas, hispanics and native americans hit hard and certainly we've invested a lot of efforts in those areas. there's still a lot of vulnerability. you know, coronavirus affects anybody. if we let our guard down, reluctant to follow guidelines. social events -- social events are what are given a kerr taebl hard time. those are scenarios that can't be safe right now, unfortunately.

that's where we're seeing a lot of it, more in subsets of the white population. >> so when you're talking about social events, are you seeing weddings, that's something we're seeing across the country why are dozens of people, sometimes hundreds of people getting together and having a wedding. are those the social events you're talking about that seem more likely for white folks to be engaged in rather than black folks. >> not weddings so much but that certainly is something. a lot is youth-based. a lot of parent-sponsored youth events, dances, parties, things of that nature that have really undermined a lot of our efforts to keep the schools open. it might be smaller stuff, get togethers, people in bars and that sort of thing. it kind of crosses the entire spectrum of high-risk activities. we know what we can do to prevent transmission of coronavirus. it's a little bit maddening that

we kind of find ourselves caught between the severe dichotomy of either shut down or open up. in the middle a nice place where we do simple stuff, stick mostly nuclear families, household contacts and wear a mask in public. then if you're going to have a social gathering do it in small groups and outdoors. it's that last piece that's really hard for us to get past, in addition to the mask thing, the these are driving the last weeks. >> it's something people can gain knowledge from. sir, thank you for being with us. >> thanks for having me. russia was the first country to approve a covid vaccine but there's no evidence the kremlin is actually way behind other countries in their vaccine development despite sticking several steps in the safety process.

a major development in the race for coronavirus vaccine. the pharmaceutical company moderna now hit target of 30,000 participants for phase three vaccine trial. the company says all of those in rolled have received their first vaccine shot and most have also received the required second shot. moderna's president said if all the stars align, his company is now on track to apply to the fda for authorization to put the vaccine on the market in early december. now a cnn exclusive on russia's push to develop a coronavirus vaccine, the developers of russia's touted sputnik-v coronavirus vaccine revealing the vaccine has not undergone the same rigorous testing required in other global trials. cnn's fred pleitgen is reporting from moscow with exclusive details. >> reporter: hi there, brianna, in august the russians approved

sputnik-v without going through main phase three trials for efficacy and safety of vaccine. however, the russians kept on saying they were going to conduct trials quickly. last week they said 10,000 people, this week 17,000 people. when we exclusively spoke to the head of the institute responsible for the sputnik-v vaccine, the head of that institute told us so far only around 6,000 of those participants had actually received both doses of the vaccine, when, of course, are key to achieving immunization and for the scientists to be able to collect data from trial participants. the other thing we've also learned is this vaccine, the institute says, is suitable for people between the ages of 18 and 60 and also not suitable for people who have various illnesses and also allergies as well. however, the head of the institute says he believes it's

still fine to also give the vaccine to older people and also to people with most illnesses. of course, many prominent russians have already taken the vaccine but one notable exception remains the russian president vladimir putin who for months has remained in isolation essentially inside a bubble, brianna. >> all right, fred. thank you for that report. our special coverage continues now with jake tapper. welcome to "the lead." i'm jake p taker. we begin today with our 2020 lead. in a matter of just hours we're going to see the final presidential debate of this presidential election, just 12 days ahead of election day. either one of the last opportunities for president donald trump and democratic nominee joe biden to make their closing arguments to american voters. while biden has been off the trail we're told getting prepared for the debate, the president has been holding big rallies across the country, potential coronavirus super spreader events, officials say and
