tests have are sufficiently accurate and available in order to contact this? >> senator, thanks for the question. for the first several trials, when they mature, we will not yet have data that bridges between a clinical outcome, which is the, of course, primary end point we've required for showing its effectiveness. that is, the previous of covid-19 illness and the development of antibodies. so it is unlikely in that situation, although again, i can't prejudge the data we'd have a requirement. again, the data will point in that direction. for subsequent trials if in fact there is bridging damt ta or from the original trials one can imagine a situation that would occur. but again, don't know that because we haven't seen the data yet, sir. >> thank you for your brief answers. i yield back. >> thank you, senator cassidy.

senator kaine? >> i want to say a word to you senator alexander, how much i'll mitt you as chairman of this committee. i learned a lot how to be a good senator from working with and also observing you and i'll miss your friendship and leadership. also i just want to acknowledge what it means to have 200,000 people in this country who are no longer with us. my wife and i have four friends who have died of coronavirus. we have preexisting conditions now and hopefully antibodies that might do something. both have had coronavirus. i agree with the chairman. opening comment as of march 1, john hopkins best prepared to deal with this and i believe that. yet i think the management beginning with our preparation and resources we have as a country, the management of this crisis has been one of the worst failures of domestic governance in the history of this country. and don't believe me. i mean, i'm just a u.s. senator.

but when people who are staffers on the task force are resigning and saying the same thing, i think we've got to pay attention to that. and i'm also mindful of the fact that during this crisis, not for a second has this administration stopped its concerted effort to take health insurance away from millions and millions of people. i can only imagine how much worse this would be in virginia, 400,000 people didn't have medicaid expansion. many are hoping to see what it will be like if we take health insurance away from millions of people. we may have the opportunity to see that. one of the reasons i think this visit has been handled so badly is not because of the dedication of wonderful professionals. we have wonderful professionals who are very dedicated, but i think it goes back to communication. i was a mayor and governor, dealt with a lot of crises. weather crises, hurricanes. mass shootings at virginia tech when pie was governor. h1n1 when i was governor, none at the scale of this. but one thing i learned tr

dealing with crises is communication. clear communication to people who are worried is absolutely critical. and that's where we have fallen down on the job with a president who's preached hydroxychloroquine or bleach or disinfectant. the day the administration laid out guidelines for states on reopening, my governor a doctor, good guidelines i'm going to follow them. the next morning the president tweeted out a tweet liberate virginia against this tyrannical governor who is following my advice. and we've seen so many other examples of poor communication. or mixed messages. that's really confused the public. dr. fauci, just this week a key communications staffer at the nih had to resign outed as snb a conspiracy laden website trashing you, trashing other public health professionals, trashing your advice about mask wearing, suggesting this was just a hoax or an invented

crises. my four dead friends would say it wasn't an invented crisis, and dr. redfield, i was very, very concerned when the cdc changed its website this week about how the virus is transmitted and would like to ask the slide be put up. this is going to be very hard to read and so i'll sort of bring it to your attention but the cdc, i believe on the 18th of september put up new guidance based on just the ongoing analysis of this crisis about what we could do to protect ourselves and how the virus is transmitted. but then almost immediately, reversed it. what about the september 18th version that's on that screen was incorrect? >> thank you, senator. i think what i tried to comment before, that this was a first draft document. >> i heard that. yo wa i don't want to ask that question. what about it was incorrect? >> it's looking at the balance of the component that air-sized transmission plays compared to

droplet transmission. >> let me read you to examples. the version posted on the 18th. people infected do not show symptoms can spread the virus to others. clear, unequivocal. you changed it back to, some people without symptoms may be able to spread the virus. now, is that phrase, people who are infected but do not so symptoms can spread the virus to others. is that inaccurate? >> let me just -- set the stage here. the document that it was reverted to was the original clear document. it wasn't the changed document. >> i understand that, but back to my question. is it inaccurate to say people who are infected but do not show symptoms can spread the virus? >> absolutely they k. that's accurate. isn't it? >> absolutely. >> the document further said there is growing evidence that droplets and airborne parseiccals can remain suspended in the air breathed in by others and travel distance s beyond si feet, for example, during choir

practice, in a fitness it class. accurate? >> definitely accurate. >> no inaccuracy. >> definitely evidence of that. >> but that was removed in the changed document and we want to its original form which didn't mention -- >> i want to highlight. not that anyone was removed. >> no. it's not on the website. correct? >> the technically cleared document that went through the proper channels is what was put up. i can say that all of these decisions about the air-sized document was made by career staff individuals far below my level as director when they saw this non-scientifically cleared document go up -- >> well, i'm over my time. i understand, but the point i'm trying to make is, we need to communicate clearly. when you put up a document at the cdc that you have just testified is accurate, and then it's changed to suggest that the risk is more minimal by someone for some reason, it contributes to the massive confusion that is

so, so troubling to scientists and so troubling to people, and then that leads to, gosh, is a vaccine going to be safe? >> yae. i want to stress for the american public and everyone here that that document that went up was a draft,not been technically reviewed by cdc. reverted to the document that was technically reviewed. there is going to be a technically reviewed document on this issue coming on the website, but the one that was posted on friday was not technically reviewed, and as a consequence, the career scientist at cdc took it down, put up the technically reviewed document until the new technically reviewed document could be posted. >> you testified that the one taken down was accurate. the point i wanted to make. >> thank you, senator king. >> senator murkowski. >> thank you, mr. chairman, and gentlemen. i want to echo senator collins

comment and her thanks and appreciation. i share that. i know that there is plenty to argue and quibble about in whether or not communication has been clear or not clear. i think we do owe that to the american public. but i also know that the work that you and those that are a part of your team is hard, hard, arduous work and you have definitely been put to the task so i appreciate the work that you do. i direct my questions to you, dr. redfield. first, thank you for cdc's effort to help our state and local public health departments. recently we had a cdc team deployed to anchorage to assist us there with an outbreak of covid we had seen within our homeless population, and you have been, you were quick when asked, and we greatly appreciate that assistance. i want to speak about, i want to

ask you about the interim guidance, interim guidelines that states are considering as their drafting they're plans to be submitted for mid-october. it goes to senator kaine comments about additional clarity i'm hearing from my state. specifically, and in the allocation, first allocation -- >> we're going to drop out at least from now this important hearing. senate health commit up on capitol hill. four members of the response team delivering important testimony. number one head of the fdaened other scientists promising no vaccine approved even more emergency use here in the united states without independent scientific review. fda commissioner dr. stephen hahn promising he will bend to pressure from no one. that, of course, from the president, repeatedly says a vaccine will be available and available soon. the doctors also making clear that, yes, they have mixups on the cdc websites.

insist not because of political pressure from the white house. democrats voicing a great deal of skepticism saying repeatedly guidance posted on government websites that seem to minimize, make less serious the threat of coronavirus and actions you should tay, democrats pressing scientists there. discuss what we've been hearing with cnn's elizabeth cohen, our cnn medical correspondent and dr. leanna wen, an emergency room first at george washington university. several interesting exchanges here. elizabeth cohen, start with you. on the pressing issue for dr. hahn, who, of course, has watched the president travel the country at his rallies saying the vaccine is coming very soon, very, very soon. very soon. perhaps before the election. he went out of his way to make clear we have an independent process. there's a scientific process. and that essentially sticking his neck out saying, i will not accept pressure from anyone, and in parentheses, that means the president of the united states. >> right, john. i've spoken to many people who

have worked with dr. hahn in the past who know him and say they believed him when he says this. they're not really worried about dr. hahn. what they're worried about is that the president will bigfoot dr. hahn either on his own or through secretary azar. not worried about dr. hahn's integrity but he'll be bigfooted and the decision made for him or basically instead of him. >> and listening to this play out. what jumps out most significant from the point of somebody watching at home trying to figure which course to take and who to trust? >> i think that's a key word, john. what stood out to me, so many of the questions were about trust. and this is a position that i could not have imagined that we would be in several months ago. because the cdc, the fda, these are some of the most revered institutions in the country. they were known for their scientific rigor, for their independence, and i could not have imagined them ream in the

public health community outside of the federal government it would say things like, i don't know if i trust the recommendations coming out of the cdc. i don't know if maybe we need external review of these recommendations, because we just don't trust that there isn't political interference. and i have to say, 200,000 deaths later, for us to be cut off at the knees, because the top institutions are unable to deliver on their core duty to the american people to protect everyone's health and welldeeg -well-being is is wab as establishing trust and credibility. i hear the right words but want to see the appropriate accesses that follow. >> one of the problems we've had throughout this pandemic is people trying to play doctors on tv. today there's a senator who actually is is a doctor, who got into a feisty exchange with dr. fauci, rand paul is an ophthalmology and someone who believes it was wrong to shut

down. believes if we let the virus run its course we will all develop herd immunity. listen to this contentious exchange, mixing or using statistics that don't apply and dr. fauci taking very clear issue with the doctor and senator. live. listen. >> you've lauded for their policy. highest death rate in the world. how can we probably jump up and down asands governor cuomo did a great job. >> you misconstrued that, senator and done it repeattively in the past. they are looking at guidelines we had put together from it task force of the four or five things are masks, social distancing, outdoors more than indoors, avoiding crowds, and washing hands. >> or they've developed enough community immunity that they're no longer having the pandemic, because they have enough immunity in new york city to actually stop it. >> i challenge that, senator. >> i'm afraid -- >> please, sir.

i would like to be able to do this because this happens with senator rand all the time. you are not listening to what the director of the cdc said. that in new york, it's about 22%. if you believe 22% is herd immunity i believe you're alone in that. >> dr. wen, you're a former health commissioner for the city of baltimore. did anything dr. rand paul or senator rand paul say make sense to you? >> no. it's not correct. i think it really is important for us to listen to dr. fauci for us to speak with science and public health. in this case, if we want to aim for the so-called herd immunity, through natural infection, we would need at least 60% to 80% of the population whom have protective response against covid-19. for us to reach that level. first of all, we don't know whether immunity lasts, we don't know whether if you get exposed once whether you're protected for months or years. in fact, it looks like it's more

on the order of months. but for us to reach that level, we're talking about hundreds of millions of people in this country who would need to be infected, and that means that we would get at least 2 million people who would have to die to reach that level. and i don't think any of us should be ready to accept that, when there are actually preventive measures dr. fauci are and so many have been speaking about. social distancing, mask wearing, hand washing, avoiding crowds, avoiding indoor, crowded indoor spaces as much as possible. we can do that and save lives. let's not use fall statistics to minimize the situation when actually we have a very contagious disease among us. >> it's a critical point you make. throughout this testimony and you have to, we have to connect the dots, because these four gentlemen all work for the president of the united states. they all have to try to pushed administration policy knowing the president often pushes back against them. to your point about herd immunity, dr. redfield, preliminary study shows 90% of americans not touched by the

virus. meaning 90% of americans susceptible to this virus at a time the president says we have turned a corner. admiral, dr. redfield and dr. fauci all insisting, wear your masks, stay away from crowds. the president traveling the country, large crowds, mocking joe biden for routinely wearing a mask. elizabeth, talked about it at the beginning. another big question, will americans have confidence if the government tells them we have approved a vaccine. whether for widespread use or emergency use authorization, will the american people trust it after we've seen all of this for months? elizabeth warren added a new twist suggesting head of the operation "warp speed" dr. slowey has a conflict of interest. risen. >> we had established a very bright line between "operation warp speed" and fda. we do not participate in their decisions. >> dr. slowey has conflicts of interest. so to boost the public's

confidence, shouldn't he eliminate these conflicts? >> senator warnen, i am not aware of the conflicts you're describing. >> if these conflicts exist, should re resign? >> in a hypothetical situation that you're describing, again, i can't prejudge because i don't know the facts. but i do take very seriously the issue of conflicts of interest and how that might affect public perception. >> elizabeth, senator warren saying, i know you've spoken to mr. slowey, he has a financial stake in at least two pharmaceutical companies trying to push and rush through getting a vaccine approved? >> john, this is something that has to be sorted through by an ethics kms, people looking at what were his investment, what aren't. all beyond the scope of what could be talked about sort of in a quick, simple way. whether or not he has conflicts, though, i think is not what at the heart of the mistrust. that mistrust is so there.

dr. wen referred to it. a poll just came out from pew saying that only half of americans say they will get a vaccine. that's a huge problem. we're not going to reach herd immunity if only half of americans get a vaccine, probably. that's probably not going to work. so that is a real problem, and i think what's at the basis of this mistrust is when you see public health officials say one thing and take it back and then say i didn't really mean it. i was struck, for example, when dr. redfield testified today he talked about guidance that the cdc had put up that said, if you have been exposed to someone with covid and you're asymptomatic, feeling fine, you don't necessarily need to get tested. and he said that many people misunderstood that and so they changed it. come on. he's gaslighting people. nobody misunderstand it. the cdc said something not correct and so they changed it. and this is one little chip in the trust of the american

people. if dr. redfield to say, look, said something in the wrong way so we're changing it, i think people would trust him and would trust the cdc. when he says something and then says, oh, no. you just misunderstood me. that's gaslighting and people don't trust gaslighters. >> especially when the changes in just about every case, the new language, tends to minimize. tends to suggest we need less testing, tends to say it doesn't spread as easily assess we might think. that's raises suspicion as well. elizabeth cohen and dr. wen, thank you for your time. a quick break. very important developments unfolding. the grand jury hearing the breonna taylor case in kentucky is about to deliver a report. the prosecutor will speak later today as well as the mayor of the city of louisville. we'll be right back. mike. an army family who is always at the ready. so when they got a little surprise... two!? ...they didn't panic. they got a bigger car for their soon-to-be-bigger family. after shopping around for insurance,

they called usaa - who helped find the right coverage for them and even some much-needed savings. that was the easy part. usaa insurance is made the way liz and mike need it- easy.

trach you straight to louisville, kentucky on the breonna taylor case. >> start to head home and be home by 9:00 p.m. nir in addition to these orders

downtown corridor including metro and city hall will be closed the rest of today and tomorrow. and i'm asking downtown area businesses to allow employees to work remotely as well whenever possible. to provide more detail on our plans here is the pd chief schroeder. chief? >> thank you, mayor fischer. >> the past several months have been difficult for our community and for the police officers pledged to serve our public. we as a community need to move forward. over the past several months, the pg has be gchlpd has been w procedures to better reflect community expectations. today's announcement is another step moving ahead for this community. whatever the decision is, our officers are prepared to keep doing what they have been doing continuously since may 28th.

protecting the public while also ensuring the constitutional right for people to express their feelings in a lawful and peaceful manner. as mayor fischer said, we are prepared for gatherings including large gatherings, and we have been working to ensure people have a safe space to do so. in addition to the measures the mayor outlined, we have restricted the area immediately adjacent to jefferson square park to vehicular traffic allowing pedestrian traffic only. we have put barriers in place to enforce those safety limits. there is also no parking and limited vehicle access from broadway north to market street and from second street to ninth street. anyone heading to the park is asked to ride share. to cut down on the traffic, but must also be prepared to walk a few blocks. we are facilitating anyone with a.d.a. concerns with access at sixth and market streets and working with residents, business

owners and downtown employees to allow needed access. to get into downtown, you may go to second and jefferson, ninth and chestnut, eighth and market and seventh and broadway. to get out of downtown, you may go to ninth and jefferson, second and chestnut, and third and market and fourth and broadway. to ensure adequate staffing we have canceled all vacation requests and off days for our pd members. while much of our focus is in the downtown area where we have seen previous demonstrations and most of the focus has been centered, i assure you, we have resources distributed throughout the entire metro prepared to meet any challenge we may face. the pd will also be joined by various state, local and federal partners helping to keep our community safe and we appreciate their assistance. i know for many these steps have been causing inconvenience, but given some of the crowd sizes we saw in the early days, and what

we have seen nationally in protests in other cities we must take these steps out of an abundance of caution to keep this community safe. our hope is that people will lawfully and peacefully express themselves. we will not tolerate any violence or destruction of property. let's all be safe. then come together and work on the challenges we face as a city and as a nation. thank you. >> listening to the police chief in louisville, kentucky, now putting in place, explaining to the push lick, traffic restrictions, curfew restrictions because they are expecting large demonstrations because we are moments away from a very important legal announcement. the attorney general state of kentucky about to announce the grand jury's findings in the investigation into the death of breonna taylor. 26-year-old emt shot in her home by louisville police officers back in march. a case not only drawn considerable controversy and contention in kentucky but nationally as part of this summer's racial reckoning. bring in our justice

correspondent. shim shimon, a long-awaited decision. the mayor and police chief essentially preparing the city for what they protect tonight. whatever the verdict is out of this grand jury, whether or not to go ahead with charges, they expect demonstrations in the city of louisville tonight. >> yes. they do exactly. and behind me is that park, that area that the mayor and the police chief here are talking about. jefferson square park. since word of the announcement has been getting out, a lot of people have been starting to stream here. some of these people have spent weeks here, in what has become an area for a vigil, a protest. now today finally we get word this announcement is coming. just to let you know, two things are happening here. courthouse, a judge is suppose stod hear the decision from grand jury about 1:15. the judge will take the decision

from the grand jury and that at 1:30 we expect to hear from the attorney general who will have a press conference, and talk about charges or no charges. what a lot of people here are waiting to hear is if any of the officers who were involved in this shooting are going to be charged. if any, if one officer, if all of the officers, and specifically what those charges will be. of course, a lot of people have been paying attention to one of the detectives who fired ten shots. the police said blindly. he was fired from the police department. his name is detective brett hankenton. a lot of attention will be paid towards him to see what this grand jury ultimately decided about him and the fact that he did fire these shots blindly as the police said ten times. and just also to give you an idea everything going on around here, john. the security around this area

has been, in the last hours very tight. police put concrete barriers along the downtown area. this area specifically. that's city hall. you have the courthouse. also you have the local jail, the department of corrections. all of this boarded up. this is a lot of what the city, the downtown area specifically looks like. you heard the mayor saying he wants people to work from home, to allow businesses to work from home. a lot of the stores to remain closed. it was real concern here that there could be some potential for unrest, and that is why they're putting all of these measures in place. also they have a state of emergency in place here. also it's possible we could see the national guard called in at some point. there's a lot going on. the other thing you might see, like some people behind me here. this is an open carry state. so you're allowed to walk the streets with these long guns. we've been seeing a lot of that

around here as well, john. and so people here, like the rest of the country, really so many people across the world, are waiting for this decision, which we should start hearing around 1:15, a short time from now, john. >> and shimon, walk through some of this for people following this case around the country. one of the sources of frustration and certainly controversy, and concern, from the many of the demonstrators who just believe they're worried it will be another case of violence against a black american shoved under the rug, if you will, that the city recently agreed to a landmark. $12 million wrongful death settlement with the family. it's six months plus now. which led to a lot of the community to say, why? why is it taking so long to investigate this incident that happened more than six months ago? >> reporter: yeah. and that is the big question. and why is it -- why has it taken so long? the other thing is a lot of people feel the pressure that

they put on the state, on the investigators here. finally it led the attorney general of this state to go ahead and present the case to a grand jury. they feel that pressure, the pressure we've woo also seen across the country of civil unrest and the protests that we have seen around the country for people calling for police reform. this city, as you said, that $12 million landmark settlement, also the police department here made changes after this incident. if you recall, what happened in this case, with breonna taylor, it was a no-knock warrant. they barpg ebarpg barged in jus midnight. her family said and her boyfriend in the house at the time say they didn't know it was the police. no one identified themselves. we're going to hear from the attorney general in fact that that was the case. the family saying no one identified themselves. so the police here made some changes as a result of that.

the fact this was a no-knock warrant and instituted a policy banning no-knock warrants. so we have seen some changes with police. the police departments across the country, really, as a result of what we saw happen to george floyd and other places as well. the big thing here for everyone here, really, is exactly what is this grand jury obviously going to decide? and how that plays out is certainly something that is very concerning to everyone here. >> the republican attorney general of kentucky. continue to follow that story. a busy day in washington. a big coronavirus response hearing up on capitol hill, and ruth bader ginsburg, the late supreme court justice lies in repose at the supreme court building. we'll be right back. i felt like... ...i was just fighting an uphill battle in my career.

live pictures here. that's the supreme court here in washington, d.c. the body of justice ruth bader ginsburg lying in repose at the supreme court where she served 27 years. thousands of people expected to pay respects over the next two days. this morning former president bill clinton, who nominated justice ginsburg to the court back in 1993.

former first lady hillary clinton former secretary of state hillary clinton as well honoring justice ginsburg this morning. amp two days at the supreme court, friday justice ginsburg becomes the first u.s. woman to lie in state at the u.s. capitol. that reserved for the most distinguished government officials and military officers. standing by at the supreme court is our supreme court reporter ouri arian devoe. during thighs somber ceremonies thousands, thousands, expected to come by and pay their respects? >> reporter: right. a somber day at the supreme court. justice ginsburg paying her final time here at the supreme court. 150 of her former clerks came by and accompanied that casket up the stairs, up the stone stairs behind me, and they will stay and guarding that casket all

through today, working in shifts, and even all through the night, even when it is moved inside, and all through tomorrow, in many ways those clerks are her most lasting legacy. it i've talked to a few of them who said they learned a lot of lessons about the law from ruth bader ginsburg, about precision. administrative law. they learned a lot more from her about life. life lessons. earlier we did see former president bill clinton, keep in mind, he was the one who put her on the bench in 1993. and her legacy in the last few years was really in the areas of dissent. she would write these strong dissents pushing back at the conservative majority, in the areas of voting rights, for instance. women's reproductive health. and pay discrimination. so that is her legacy now, and what's left is for those clerks that we saw in many ways, they've gone back out into the

world. they came here as young lawyers. they got thus amazing credential. they went into the their various careers, or whatever they were doing in the world, and now they're her legacy, and she'll -- they're the ones who will carry it on for the future. >> all right. outside the court for us. very important. a bruising confirmation battle is ahead for the nominee. president trump will send up to replace justice ginsburg. very important to take time, as you just did, to rep her remarkable life, legacy of ruth bader ginsburg. thank you. a very busy day including on the campaign trail. joe biden heading to battlegrounds in north carolina urging african-americans to turn out in high numbers.

more dangerous and corrupt president than trump. he's harming our basic values, giving rise to hate, and he's selling out america to big corporations. i'm working to protect immigrants, women, communities of color, and lgbtq people. and i'm making corporations like pg&e and insurance companies play by our rules. we need experienced leadership to wipe away trump's stain on america for good.

joe biden campaigning in battle'sground north carolina today and this comes an interesting moment in the campaign. first debate just days away. new polls showing perhaps in some battleground president trump starting to creep back in to the race. look where we are now. we have the map lopsided in favor of joe biden. doesn't mean trump can't win. president trump at 169 electoral votes. north carolina befokarl karcaro today considered a battleground. showed a dead heat before. look at this post from abc news. florida, statistical tie, advantage president. arizona, a statistical tie. and trump in numbers but

pollsters tell you that's is a tie. make no mistake map is lopsided in biden's favor. see a trump path to victory? florida, showed you that poll. its dna is republican. arizona, we leaned it blue right now, but it if a poll is to be that believe pd and om one. don't invest in one poll. certainly within the realm of possibility trump could come back and win arizona. ohio the most republican of battleground states by dna. the president can certainly win that. georgia, yes maybe a year it changes but long a republican presidential stronghold. north carolina, close. trump won it last time. look what would happen if you do that. look what happens if you do that? it all comes down to pennsylvania, and maybe two congressional districts here and here. which is why as biden goes to north carolina today he knows if he can get this state, biden can get this state, he can block trump's path. plain and simple. joe biden wins north carolina, donald trump is not winning a second term. one of the key aspects there, this is him on the "steve harvey

show" this morning. get african-americans to come out to vote. joe biden says i have a plan to help with economic development. new money and a new team at the white house to get through all the red tape. >> so we're going to have a place in the white house. we're going to provide navigators for people with good ideas for business and enterprises and access for them to be able to borough the money and know where to go to get the money in the first place. so the whole idea is to build wealth. >> bring in "talk politics" white house reporter for the "wall street journal" and reporter from the "washington post." and you see battlegrounds and saying, 2016. here we go. the trump comeback. be careful. no one should invest in any one poll, but the bottleground states of close. biden goes to a place like north carolina, a little chess involved. one of the states that were it

to go back to blue -- hasn't been there since 2008 -- almost impact to see trump win if he can't win north carolina? >> that is right. same of florida. right? always a pivotal battleground state. everyone expected the race to tighten. we now have unpredictable dynamic of a supreme court confirmation hearing happening basically right before election day, looks like. the fact that this comes at a surprise. you see looking at the map biden still has more potential path to victory here. that's the name of the game in presidential races. you want as many, maximize your number of paths to victory. one place that a lot of people are really looking at is arizona. that was a state that wasn't all that open to hillary clinton, which is definitely on the map this time around as a battleground. >> and listen to -- not quite sure i believe this. this is joe biden asked how's debate prep going.

he said this. >> reporter: have you started preparing, and getting ready for -- >> started to prepare but i haven't gotten into really heavily. i will, beginning tomorrow. >> these debates are incredibly consequential and says i haven't gotten into it really heavily. we will beginning tomorrow. i find that a little hard to believe. >> yes, john. i think there has been a lot of prep going on behind the scenes. the campaign knows how important this debate is for the biden campaign. it really is. especially given the remote nature of most of the campaigning. biden doing very small -- debates seen as a final moment to impress upon voters. maybe voters just tuning in. it's a small universe of undecideds at this point. the debates are seen as one time you might be able to reach them. >> we know from the moderator, chris wallace. moderators picks the topics in

presidential debates and the supreme court nomination will be one of them. the president will make his pick saturday. the candidates meet onstage early next week. lisa, doesn't look like democrats can stop it. looks like republicans have the votes in the senate to bring the nominee to the floor and perhaps to confirm that nominee before election day. but we do know the pick and the issues at stake will be huge in the debate. here are the two candidates warming up. >> this is the one chance under the constitution where the american people have an opportunity. to rush this is just close to just -- there's just a fundamental violation of constitutional principles. >> we need nine justices. you need that. with the -- unsolicited millions of ballots, it's a scam. it's a hoax. everybody knows that. and the democrats know it better than anybody else. so you're going to need nine justices up there. >> the president even intimating

there he needs nine justices in case there are challenges to the election. one might argue a conflict of interest, one newly confirmed. a major flashpoint. issue of just this squirmaticoa or on abortion rights, on obamacare and so on? >> exactly right. hard to underscore how high the stakes are for this confirmation battle. getting a conservative justice in this spot would be the culmination of a decades -- long project by republicans to tip the court overwhelmingly in their favor. and's democrats, for their part. that plays out exactly as you point out in all issues so crucial to both parties but particularly to democrats because a lot of it would be undoing some of the things that happened during the obama administration, like affordable care act. potentially abortion rights. there are issues here, but these

large -- the other -- issues as were el. things that it strike particularly deep floor joe biden who's really an institutionalist of the senate and someone who oversaw more than a dozen confirmations of supreme court justices, and voted on those confirmations during his time in the senate. so i think this is a deeply personal issue to joe biden, but also to president trump, who this is a piece of his legacy and on the issues, the stakes are overwhelmingly high for both parties. >> thank you both for the reporting and insights as we head into an important stretch of this campaign. and the widow of john mccain endorsing joe biden. see her explain this in person later today right here on cnn. jake tapper can on "ed lethe le 4:00 p.m. eastern today. we'll be right back.
