good evening. chris cuomo is off tonight. we begin with the examination of a candidacy this country has quite literally never seen before. kamala harris will become the first black woman as well as the first asian woman on a presidential ticket. praise pouring in from all corners of the democratic party. president obama said her own life story is one that i and so

many others can see ourselves in. no matter where you come from, what you look like, how you worship or who you love, there's a place for you here. hillary clinton tweeted i'm thrilled to welcome kamala harris to a historic democratic ticket. she's proven herself to be a leader and i know she'll be a strong partner with joe biden. please join me in having her back and getting her elected. val demings of florida, herself a potential vice presidential candidate. she wrote for a little girl who grew up poor, black and female in the south to be considered during this process has been an incredible honor. i feel so blessed. to see a black woman nominated for the first time reaffirms my faith that in america there is a place for every person to succeed, no matter who they are or where they come from. we've got multiple reports on why and how joe biden picked her as his running mate. we'll also speak with one of the democrats who ran against her during the primary season and now praises the pick, senator cory booker of new jersey. while we'll spending much of this broadcast on this nomination, we'll also bring you

reports on the coronavirus, including what will become on the college football season and a new study on the safest masks. we begin with senator harris' historic candidacy. joining me now is jeff zeleny. let's talk about how this decision came to be. >> anderson, there's no question it's the biggest decision of joe biden's presidential campaign and indeed his political life. he of course won the democratic nomination and said he would pick a woman as a candidate, so he really cast a wide net, looked at 11 candidates we are told in a very deep way. extensive vetting of all those candidates. but it was senator harris' name who kept emerging again and again. she was seen as one of the strongest contenders at the beginning and of course at the end as well. i am told, anderson, that she learned of this decision only 90 minutes before the announcement was made this afternoon. during that intervening time after she said yes, you can see the photo right there, it was during a zoom call that she had with the former vice president, who's in delaware and she was here in washington, during that period of time, he was calling the others who were also

finalists. elizabeth warren, for example. atlanta mayor keisha lance bottoms. the michigan governor gretchen whitmer. so of course the decision for kamala harris i'm told is based on a couple of things. first and foremost, she has run for president before. she's tested on the national stage and the former vice president thought it was critical to have someone who had been tested before. he's basing it on experience, of course. throughout this whole process he was looking for his own biden, if you will, based on his own experience as the former vice president to barack obama. at that point he was chosen because he had experience on the national stage so he thought that was critical. of course the historical nature of of this cannot be understated. that also was part of this, just given what's been happening in the country for the last several months, anderson. >> jeff zeleny, thanks very much. for more on senator harris' new life as the presumptive democratic vice presidential nominee, let's bring in jessica dean. do we know if senator harris is at her home tonight? do we know how today played out

for her? >> great question, anderson. we know that she was last seen here at her d.c. home on sunday. but we had crews here as early as 6:30, 7:00 this morning and no one has laid eyes on her so far today. they did see her husband, doug. he came out, grabbed a cup of coffee and went back inside. we have not seen harris outside her home here in d.c. i know jeff showed you this photo before, but we know that she did speak to former vice president joe biden today, as you saw in that picture. they talked over video chat. he informed her that she would be the nominee. and really just a moment in time right there. we're in the middle of a global pandemic. you have the democratic nominee informing his running mate via video chat. and of course she's making history as well as the first person of color to be -- female person of color to be nominated for vice president, anderson. >> so they're going to appear tomorrow together. do we know anything about how that's going to go down, what the event is? >> right.

so first tomorrow we will see them together in person. they are going to give remarks in wilmington, delaware, where former vice president joe biden is located. so she will make her way to delaware. they will give remarks together. we're told that that's going to be about restoring the soul of the nation, which is what we have heard joe biden say over and over again on the campaign trail as one of the main tenets of his candidacy so we will get to see them interacting with one another. of course they can't hold a big rally. typically when this is announced, we would see kamala harris and joe biden together in front of a huge crowd of screaming supporters. that's just not going to happen during this pandemic. instead the campaign is doing a grassroots fund-raiser tomorrow evening that they're inviting all supporters to join in. and again we'll start to get to see the dynamic between harris and biden play out. >> jessica dean, jessica, thanks very much. democrats are praising the choice of harris, includes this tweet from the only other african-american democrat in the senate, cory booker of new

jersey. he said, quote, i'm proud to call kamala harris my dear friend and sister and next year i'll be even more proud to call her our vice president. this is history. kamala is a trail blazer who will serve this country well as the first black and asian american woman on a major party's ticket. senator cory booker joins us now. senator booker, thanks for being with us. you and senator harris have a long friendship. you competed against each other during the race. when you reflect on this moment both from a political standpoint but also as an american, what does it mean for the race and the country? >> well, i mean i'm so happy. it's been hard to control myself feeling joy. you have to understand i've known kamala, so i know her as a friend and a sister. even when we were campaigning against each other, i'd always remind the press, there may be sibling rivalry, but don't lose the understanding that we're still family. and so don't mess with her. and so i just -- the woman that i know, let's set aside everything about the historic

nature, gender, race, and more. i'm just telling you, i've worked with her behind closed doors when the work is getting done and seen how competent and qualified, how focused on the detail, how great of a negotiator she is. and then i've seen her in the larger context where america has seen her, someone who is so profoundly charismatic, the ability to connect with people, whether it's a small town hall or a large audience of thousands. she is a gifted leader. but now when you add that to the fact that there are -- my phone is blowing up by people that are not political, by folks who just -- it's like that old movie waiting to exhale, who are just i am seen, i am valued. this country is including me in a way that we have seen doors close, by a woman, a black woman, a howard graduate, an aka who every step of her career

climbing to the highest heights of a political ticket, she's had to blaze her own trail. there's been nobody before that served in a lot of her positions that was an african-american woman. so she's just someone that i'm excited about, about, you know, the people in my life who are going to look at her and get so inspired by this being a nation where anything is possible. and add that to the fact that she's just going to be the greatest wing woman you can ever imagine to joe biden. this is an exciting day. it's an historic day and a day of personal pride for me of someone that i've known special since i was recruiting her to run for senate in the first place. >> she's obviously had some tough races going back, and experience campaigning for a number of positions in san francisco and california, obviously for president and for senator as well. how much does that experience

help her in this? running for president obviously is unlike anything else, but having run on the national stage and run at the state level and at the city level? >> yeah, well, look, you know this, anderson. when you've had to actually scrape your way up, starting in a municipal level, fighting for statewide level, you've seen every kind of crowd, every kind of challenge, all kind of cu curveballs and she has dealt with them extraordinarily well. she's an experienced, seasoned campaigner, just coming off a presidential campaign trail as well. she is ready for the job of being his running mate. and then you add that to the fact that she is someone who is representing the most populous state in america. that she has foreign policy and national security experience in the senate. that she has managerial experience from her statewide

office in california and then even with the work she's doing now. so this is just somebody that is, as joe biden said, he wanted. somebody qualified to be president on day one should disastrously that need happen. so i just think that as america gets to know her now and the many layers to her and that she's this kind of leader and candidate that people will find approachable from so many different directions that they might be coming. maybe they're an indian american, maybe they're an immigrant family, maybe they're a woman, maybe they're someone who has been a leader in organizations. there's so many things about her that people will find accessible that is just so profound. so this to me is a day of real celebration and also for me in a very personal level, i just know my ancestors, our ancestors are cheering this moment. it is one of those moments in american history that is just --

you feel it. a worn soul is feeling this moment of joy and happiness, so i'm very grateful. >> do you have a sense of -- i mean how does one run a presidential campaign, how do you campaign? i mean normally there would be a big rally tomorrow. she would be out on the trail in some locations, vice president biden would be out in other locations. you know, you would be out there, others would be out there. do you have a sense of how this will work? you know, you talk about energizing people. if people are energized, they might volunteer to work on a campaign. does that even happen now? >> one of my team members said this to me, because i've had hundreds probably, i don't think i'm exaggerating that number, of zoom calls since this pandemic in addition to fund-raisers. i'm on the ballot in new jersey, for example. one of the ones that my staff loved the most was the one that kamala and i did together, which

was a zoom campaign event. and it was funny, it was fun, it was -- i think it was one of those folks where people felt connected even though we were socially distanced by thousands of miles. kamala is good. and this kind of campaigning she will be excellent. and so i'm not worried. donald trump has the same challenges too. in fact this is a guy that relies on, we saw in oklahoma, rallies to the point where he was willing to put other lives at risk. he now has to deal with the same playing field that this -- our ticket will have to do. i will put the energy, the excitement, the enthusiasm, the ability to connect of kamala harris against vice president pence any day of the week. i'll put my heart and spirit on kamala, bet on her every day. >> you know, it's interesting. to see the president at the white house today sort of trying to figure out what's the line of attack on her, i mean, yes, the

president said she was mean to judge kavanaugh during the confirmation hearing. you know, he said she was nasty, a word obviously he seems to use often for strong women or people who ask questions or challenge him. do you think it's a smart choice in that sense of, you know, for those -- he will say that vice president biden wants to defund police. it's hard to see kamala harris has somebody who has worked in the criminal justice system as a prosecutor and a district attorney in that position. >> well, i'm smiling because if there's anything i know, and kamala is too humble to say this, but she has joined the pantheon of great black women in history. i know what they have tried to do to great black women in history, they have always tried to destroy them. ella baker, harriet tubman. i can go through them. as one great black woman wrote so eloquently, it applies to

donald trump and kamala harris. you may write me down in history with your bitter twisted lies, you may trod me in the dirt but still like dust, i rise. and this black woman aka howard graduate is used to men coming at her with the same viciousness, cruelty and meanness, and she has risen every step of her career. and so she's not worried about donald trump. donald trump should be worried about kamala harris. >> senator cory booker, i appreciate your time tonight. thank you. >> all right, thank you. >> still to come, another senate colleague, senator maze e mazie will join us. and later the coronavirus pandemic, how it may affect whether there will be a college football season, ahead. i love reviews. i've seen a huge change in my skin. my forehead wrinkles are less noticeable, and my skin is plumped and youthful! yeah. these forehead wrinkles are not fun.

my mouth were yipee! i know the other senators are my friends and all the other potential candidates are people i deeply admire, but kamala i got to know particularly sitting on the judiciary committee. you just heard from core owe bo cory booker. the three of us sit next to each other and she refers to us as the people of color and so we often vote together and are clearly on the same page on so many issues. yes, her questioning barr, i was very delighted with it because the way kamala questions our witnesses, she brings a prosecutorial experience to it. so i enjoy watching her. of course i was there because both of us were going after barr that day. joe biden was looking for somebody tough, smart, ready to lead. and he got that from kamala, in kamala. >> president trump actually attacked her today for her

questioning during the judge kavanaugh confirmation hearing. i just want to play what president trump said today and also play some of her exchange with judge kavanaugh. >> she was extraordinarily nasty to kavanaugh. that was a horrible event. i thought it was terrible for her. i thought it was terrible for our nation. i thought she was the meanest, the most horrible, most disrespectful of anybody in the u.s. senate. >> kasowitz, benson and torrez, the law firm founded by marc kasowitz, who is president trump's personal lawyer. have you had any conversation about robert mueller or his investigation with anyone at that firm? yes or no? >> is there a person you're talking about? >> i'm asking you a very direct question. who did you talk to? >> i don't think i -- i'm not

remembering. >> you have impeccable memory. you've been speaking for almost eight hours, i think more, to this committee about all sorts of things you remember. >> you were in that hearing. i'm wondering when -- again the president uses that term "nasty" it seems mostly only but certainly mostly for women who are strong. >> yes. >> and stand up to him. >> the president can't handle strong women because in that same proceeding he's called me nasty and vicious regarding kavanaugh. so that's what the president does, he calls people names. he thinks that's how he can handle the situation. of course in kamala, he's got more than he can handle. he's just lucky that pence is going to be debating kamala and not him. >> you've worked together recently on an effort to push back on anti-asian discrimination. >> yes. >> in the wake of the covid-19 outbreak. what do you think senator harris brings in these defining issues, racial justice and the pandemic

at large? >> in all of those issues, it's historic -- history making that she is the first black woman to be a part of this ticket as a vice president. but she's also very strong on asian, american pacific islanders issues and we have worked together on immigration reform bills and also to condemn the racial attacks against asian americans because the president continues to refer to this virus as the china virus. we know why he does that, it's for a specific purpose. it's more than a dog whistle, it's a bull horn. so she very much cares about api issues. in fact she was the first presidential candidate to have an api platform. and so immigration issues are major to her. she was also one of the first senators as i recall to raise the alarm about the pandemic because there were people in california, hundreds, who were coming down with this virus and

she wanted us to address it. so she's definitely forward leaning. she is a leader. and she's going to help joe biden put this country back together because after the chaos of the trump administration, we're going to need a strong team, people with integrity and commitment to people to lead our country, and that would be the biden-harris team. >> senator mazie hirono, appreciate your time tonight. thank you very much. >> thank you. i want to bring in aiesha mills. you said let's ensure this transcends tokenism and her presence translates into black people. >> yeah, yeah, congratulations to senator harris. this is indeed exciting and historic for black women all over this country. the democratic party, which i have been a member of particularly my whole life essentially has always benefited

from the labor of black women who are out there getting people excited about campaigns and certainly from our votes, which really make or break elections. and so it is about time that we have a black woman who is near the top of the ticket. but here's what i hope to see beyond this. we know that senator harris is prepared and the right person for the job and the right person to become potus one day. i want to see the democratic party value black women and value policies that lift up black people and really put now this image that we have created around a historical moment and putting someone in leadership who really reflects the soul of the party to transcend that optics to make sure that our policies are reflective of what we need in order to lift up black americans. we are in the middle of a black lives matter moment. we are constantly seeing issues around police brutality, the wealth gap, a variety of things that the african-american community in this country cares about. so i am hopeful that the party and certainly the

president-to-be biden prioritizes all of the policy issues that matter to our community and don't just say, hey, we've got a vp and walk away from black voters. >> karen, you've been through two running mate elections yourself. can you explain what happens now? how kamala harris' life will change. obviously the general election is a whole new level of politics even for somebody who's been through many campaigns like senator harris. >> absolutely. i mean, remember, she is joining the general election in progress. and so, you know, shortly i would imagine shortly after she received the exciting news and got to share it with her family, you get right to work frankly. remember, she's got to be ready tomorrow basically to hit the air waves or whatever it is that the campaign may need of her. i know there will be some fund-raising coming up. and then in a week, a week from wednesday night, she's got to deliver the biggest speech of her career. and so it's all about preparation and getting ready to -- and being ready, frankly,

to be the running mate and to fight the good fight. i mean i don't think any one of us is under the impression that this isn't going to be a dogfight. i think trump made that very clear. the attacks are already coming. but i just want to underscore as a black woman and as someone who has worked very hard behind the scenes with a number of other black women to get us to this moment, this is -- i cannot oversell how important this moment is. joe biden in selecting kamala harris and kamala harris by becoming our vice presidential nominee, this is a new chapter in the history of black women in this country. when geraldine ferraro was added to the ticket, black women were not even considered. so i don't want us to lose sight of how important this moment is and what a bold choice this was from joe biden. >> dana, there's been a lot of talk about suburban voters and how they'll be a critical piece to anyone's path to victory in november. what do you -- just on a

political sense, what do you think senator harris adds to the ticket? >> well, we don't know how senator harris does on a national level in the suburbs because she dropped out of the presidential race before any of the votes were taken. but what we do know is that strategically her campaign thought had they stayed in that that would be a good place for her to go and that was kind of one of her focuses about women in particular, but even more broadly suburban voters. so clearly she's going to hope to translate that and the biden campaign is going to hope to do that as well because, as much as this is going to be a turnout election and everything else that we have been talking about, it is still going to come back to the suburbs in so many -- in all of these swing states, from pennsylvania to michigan to wisconsin and beyond. it is the suburbs making sure

for the biden campaign that those voters who went for democrats in 2018 and helped give democrats the majority in the house, that they are going to continue on that path. the hope is that not just by having a woman, but a woman, specifically kamala harris, that that will help joe biden achieve that. >> david chalian, in terms of the future of the democratic party, obviously if they win, you know, questions remain and has been raised whether joe biden would seek out a second term, again if he wins the first term. but certainly kamala harris is somebody who you would imagine would want to have -- having served as vice president would want to continue and try to run as president. >> having already run for president, right? she actually already has sought that office and made it clear that she is interested in that. anderson, i think it's such an important point about this pick. joe biden has just put kamala

harris right to the front of the line in terms of the leadership of the democratic party in america going forward. now, i don't know obviously if joe biden is going to win in november. like you said, yes, because of his age, maybe he will be only a one-term president if he wins. if that's the case, you know, basically as soon as vice president harris would sort of leave the capitol on inauguration day, she's going to be catapulted into this position of being the front-runner for the 2024 democratic nomination. how she balances her governing partnership with joe biden, with the political reality that will take place around her will certainly be something to watch. in this pick joe biden is putting a stamp on the future of the democratic party. >> aisha, i think what you said was really interesting about giving due to the people who have provided, you know, time

after time after time the backbone for the democratic party, black women. in terms of younger -- younger people who have been taking part in the protest movements, black lives matter, how does kamala harris do you think, how is she viewed? because obviously she has a background in criminal justice. she was district attorney both in san francisco and in california. for anybody who wants to attack joe biden like president trump on -- claiming that he wants to defund police, which he says he does not, certainly kamala harris is a bulwark against that. for the left of the democratic party, how do you think she performs? >> well, i'll say this about senator harris, is that she has demonstrated leadership and evolution. certainly 15, 20 years ago when she was a prosecutor, she may have been on a different side of criminal justice reform. her ideas may have been different as a prosecutor. the role that she was able to

play in her position looked different than when she became a legislator in the united states senate. she has been very reflective, very thoughtful and also very responsive to the activity in the streets. and she has proven that she is willing to evolve her own thinking, but also be extremely receptive to young people and certainly she considers herself to be progressive and supports progressive values and progressive ideals. what we want in a leader, what young people want in a leader is somebody who's not going to be afraid to say, you know what, i've rethought that. you know what, i can do better. that is the spirit that she brings. i think that everybody can coalesce around that. it is not lost on us that she is also a possibility model as lavern cox says when, we need one. black women have always supported the democratic party. the last thing we need is for black people to be disenchanted come november given all that's going on. and for us to be ambivalent about whether or not we want to vote. i think that putting her on the

ticket is certainly going to rile some folks up and to get people excited. >> karen, what does this campaign even look like? for both sides frankly. i asked cory booker this, but is it all zoom fund-raising events and appearances on cable news and broadcast news? >> largely, yes. and also we've seen the campaign do events via zoom, sort of zoom town halls. so it will be reaching out to voters. obviously that's part of what makes this not just historic but unprecedented because we're in such an unprecedented moment. so yes, it will be zoom calls, zoom town halls, finding new ways to reach out to people, whether that's through interviews, through other platforms on social media. i think you'll see a lot of that. i think you'll see a lot of activity, frankly, on social media to sort of -- particularly because we know having been up against donald trump before, i can tell you get ready, because it's coming. i think the campaign is prepared

for that and prepared to do battle. and hopefully if there is a point in time where the candidates can actually be -- do in-person events, i don't know that we'll see that before november, but if that becomes possible, hopefully we'll see that. i do think someone said this is the first time i'm really missing the balloon drop at the convention because i really would love to see kamala harris on the stage with those balloons and all that confetti. >> well, it will be much cheaper, you can have 20 balloons in the ceiling of the room on the zoom call and that will be it, that will have to do. i want to thank you all, appreciate it. really interesting conversation. we spoke in the last hour with the man helping bankroll the coronavirus vaccine in russia that's grabbed the world's attention and some skepticism. he made a lot of claims about the underlying data and how the vaccine works. sanjay is back to talk about what he heard from the interview and his perspective ahead. we'll be right back.

achoo! ...do your sneezes turn heads? try zyrtec... ...it starts working hard at hour one... and works twice as hard when you take it again the next day. zyrtec muddle no more. for our families and for our communities. when we spend taxpayers' money, we should use it to buy american products and support american jobs. it's time to help small businesses who will purchase clean energy technologies to fight climate change and enhance national security.

we have to invest in what the jobs and industries of tomorrow are going to be. we have a great opportunity, build back and build back better. i'm joe biden and i approve this message. when you think of a bank, you think of people in a place. but when you have the chase mobile app, your bank can be virtually any place. so, when you get a check... you can deposit it from here. and you can see your transactions and check your balance from here. you can detect suspicious activity on your account from here. and you can pay your friends back from here.

dr. anthony fauci is throwing cold water on the news of a vaccine from russia.

>> having a vaccine, debra, and proving that a vaccine is safe and effective are two different things. i hope that the russians have actually definitively proven that the vaccine is safe and effective. i seriously doubt that they have done that. >> well, we just spoke last hour to a russian bankrolling the vaccine effort that putin says has been approved. >> we'll start massive vaccination of russians in october. this will be available tol other countries around november. we know the technology works and we will publish the data in august and september to demonstrate that. so the gradual rollout in august and september will give of course some additional data, but our minister of health, our bureaucrats, would not have approved it unless they were absolutely confident that the technology works. >> there's of course a lot of sk skepticism about that. proof of its effectiveness has

not been presented. i want to bring in dr. sanjay gupta. sanjay, the more we talked to them it seemed clear they haven't had phase three trials. they're in fact just going to -- they say they have done phase one and phase two and they're just going to start injecting people with this, right? sanjay, we've lost your audio, i'm afraid -- >> can you hear me now? >> now i can hear you. >> sorry about that. so you're right. they're basically talking about trying to begin phase three trials. some of the other vaccine companies that we've been talking to, some of the people we've interviewed have started those trials already. so this is something they're saying they're going to start as well. but i think we would be right to be pretty skeptical, maybe even more so after that last interview, and here's why. even the phase one and phase two data has not been presented yet. i mean we are looking at -- we

are looking for that early data to determine what is the likelihood that this is safe, what is the likelihood that it has what are called some efficacy signals, some signals that it's going to work? we haven't seen any of that data yet. remember, you're giving vaccines to healthy people. i also think it was very interesting that mr. dmitriev and other people there including scientists who have worked on this have given themselves this vaccine. he said he gave to it his parents, who were in their 70s. that's not science, that's audacity. you're giving something that is unproven, could potentially be harmful to people without really any data behind it. so that made me even more suspicious. and then finally, you know, when you're talking about these trials, he's saying, look, we're going to give it to high-risk people, people who are health care workers. and that is not an unreasonable thing. but a couple of thousand health care workers are not a phase three clinical trial. you need to get people of different backgrounds, different

age groups, different demographics, in an area where the virus is rapidly circulating so you can determine is it working in people who are vaccinated compared to those who aren't and it doesn't sound like they're going to be doing that. >> it was really interesting to me that he actually said they had not done phase three because that's basically when they announced they had this vaccine, you assume they have done all these things but they haven't. they're essentially where other companies are, they're just saying we know this works and we're going to start, you know, injecting people with it. i want to play a little bit more of what he said. >> according to russian law, when you have a pandemic, when you have epidemia like this, you know do phase three concurrently with launches of vaccines to high-risk groups, which is what we are doing. we believe this is the right approach and this approach makes sense. >> the other thing he was saying is russia was advanced because

they had already been working on a vaccine for ebola and i think he said mers. there are other people who have been working on vaccines for ebola and mers, weren't there? >> yeah, there were. and i covered ebola quite extensively, even back going to 2014, 2015. this sounds like a familiar narrative, because even back then we were hearing from the russian government that they had a very effective vaccine against ebola. i believe this was 2015. as it turns out, at that time there wasn't a vaccine that we could find any sort of phase three data for. so how they were arriving at this conclusion going back five years now, five or six years was a bit mystifying even back then. so this sounds like a familiar story, anderson. i will tell you this, you have these platforms. this is a human adenovirus platform. he's right in that other companies are trying human adenovirus. you take out the gentlemetic

machinery of that virus and put in this virus. you put it in the body and hope the body makes antibodies to protect you in the future. there are other companies that are doing this but we have no idea if it works. it's a theory. there's a lot of theories out there. there are tons of these vaccine platforms that are in clinical trials right now. the worst-case scenario, and it's not an unreasonable thing to think about, is that this could cause harm. maybe it doesn't work and that would be deeply embarrassing, but if it causes harm, that would obviously be a huge problem. again, we're talking about giving this to healthy people, not people who are sick. >> sanjay, thanks very much. appreciate it. thanks for taking part in that interview. up next, the big ten and pac-12 conferences both voting to postpone college football. espn is reporting one of the concerns for them and other conferences is a rare heart condition linked to coronavirus and have seen some in some athletes. details on that ahead.

...steering life at 10 and 2. you're prepared for this. and so are we. soon you'll get back to skipping the counter without missing a beat. back to choosing any car in the aisle. back to being the boss of you. go national. go like a pro. ...i felt i couldn't be at my... ...best for my family. in only 8 weeks with mavyret...

...i was cured. i faced reminders of my hep c every day. i worried about my hep c. but in only 8 weeks with mavyret... ...i was cured. mavyret is the only 8-week cure for all types of hep c. before starting mavyret your doctor will test... ...if you've had hepatitis b which may flare up and cause serious liver problems during and after treatment. tell your doctor if you've had hepatitis b, a liver or kidney transplant,... ...other liver problems, hiv-1, or other medical conditions,... ...and all medicines you take. don't take mavyret with atazanavir... ...or rifampin, or if you've had certain liver problems. if you've had or have serious liver problems other than hep c, there's a rare chance they may worsen. signs of serious liver problems may include yellowing of the skin, abdominal pain or swelling, confusion, and unexplained bleeding or bruising. tell your doctor if you develop symptoms of liver disease. common side effects include headache and tiredness. with hep c behind me, i feel free... ...fearless... ...because i am cured. if you can't afford your medicine, abbvie may be able to help.

two of the biggest college football conferences, the big ten and pac-12 are postponing all fall sports including football due to coronavirus.

this comes as president trump continues to press for football this fall. espn reports one of the areas of concern for all the major conferences is a rare and dangerous heart condition linked to covid-19. espn says some college athletes have been diagnosed with it. joining me now is dr. jonathan dresner who advises the ncaa on cardiac issues and is the director of the uw medicine for sports cardiology in seattle and the team physician for the huskies, seattle seahawks and seattle rain. doctor, thank you for being with us. you see the cancellations from the big ten and pac-12. you also hear president trump downplaying it a bit. i want to play a bit of what he said today. >> these are young, strong people. they won't have a big problem with the china virus. so we want to see college football start and hopefully a lot of great people are going to be out there. they're going to be out there playing football and they'll be able to fight it off.

>> so what are the problems we're seeing with athletes in this way? >> thanks for having me, anderson. i agree, these are -- our young athletes are young and strong, but this can be a serious problem. it's our job to keep them safe on the playing field. we learned early on in the pandemic that covid-19 can affect the heart. about one in four hospitalized patients have heart injury. it raised a lot of questions and concerns about patients who weren't in the hospital. would patients who had mild symptoms or no symptoms have heart injury. this is particularly important for our athletes who put themselves through quite a bit of exertional stress on the playing field, where exercise can be a trigger for something like an arrhythmia or cardiac arrest. if there is inflammation in the heart muscle called myocarditis. more recently we've been learning that some college and professional athletes are

inflicted with myocarditis from covid-19. and i think we're just learning about this issue in our athletes and it's definitely raised our concern. >> so somebody can be asymptomatic or just have a very mild case that they yet still have potential long term heart damage. >> that's correct. and we don't know how long term that is yet. it's all very new. we are learning some athletes who had no symptoms and go through subsequent testing are diagnosed with myo a carditis. the treatment is rest and recovery and guidelines. three to six months later most of the athletes can return to play safely. there are some rare circumstances where the heart muscles enough infected that is loses function. there could be elements of heart failure and long term damage.

>> it's inflammation of the heart? what exactly is it. >> yeah. inflammation of the heart muscle and can lead to scar tissue in the heart. and that can be a focus of an ab normal electrical signal in the heart and cause cardiac arrest. >> the asymptomatic nature complicates keeping athletes safe. unless they are tested rigorously you don't know they have it. >> that's right. it really raises quite a bit of a challenge to understand who has this and who is at risk. i think it's important as we think about why some colleges are pushing back fall sports. it's not just the heart issue shs but really important is we don't want athletes to get infected. if the pandemic is out of the control in certain cities kp

don't have adequate testing to ensure that when they aren't physically distancing on the playing field they are not infecting each other. it's hard to move forward with college sports. what we're learning about the heart and athletes raised that bar. >> in terms of what we need to learn before people can return to sports safely at the college level. is it just a vaccine? or is there hope that everybody without a vaccine just learning more about this down the road will improve chances? >> i think there's hope without a vaccine. if everyone does the right thing and wears a mask and the numbers fall and we neat some metrics. and begin to open up. the risk declines. if you combine that with frequency of testing to root out the athletes that might have infection. you don't want them to spread it among the team. there's a path way forward for sports it doesn't necessarily

include a vaccine. when the pandemic is more under control we have better testing, and know more about the long term health out comes we can resume sports. >> yeah. it's really fascinating. and good to know even if you are asymptomatic and have a condition. really appreciate it. thank you. the wait is over. joe biden the vice president pick will appear tomorrow for the first time. her credentials and life. and someone often on her side on the campaign trail. her husband. next. up downstairs ♪playing ♪ our house, it has a crowd ♪ there's always something happening ♪ ♪ and it's usually quite loud ♪ ♪ our house, in the middle of our street ♪ ♪ our house, in the middle of our street ♪
