captioning sponsored by cbs >> brennan: i'm margaret brennan in washington. on "face the nation", attorney general barr says he won't be bullied by anyone, including president trump, when it comes to justice department investigation. and the former front-runners, biden and warren stumbled coming out of new hampshire. the focus turns to other candidates trying to win over their supporters. and as the number of corona virus cases escalates, the tactics used by the chinese to prevent spread gets more drastic. another week of back and forth between the president and a top government official. this time it's the president weighing in on how the justice department should be handling

cases involving trump allies and perceived enemies that prompted attorney general barr to publicly reboox+*ubl buke telling the president to essentially butt out. >> his public statements and tweets made about the department make it impossible for me to do my job, and to assure the courts and the prosecutors in the department that we're doing our work with integrity. president trump's response? he's not interfering, but that he could if he want the to. >> we'll talk to an ally on the judiciary committee. >> joe biden, and elizabeth warren limp out of new hampshire and head to nevada. with former mayor michael bloomberg blitzing the super tuesday states the democrats accelerate attacks on the

billionaire. amy klobuchar scored a third place breakout in new hampshire. >> we exceeded expectations. >> talking with her and the other billionaire in the race, tom steyer. he's propelled to the top tier in that race. and finally with the number of cases surging to over 60,000, we'll talk to a doctor with the national institutes of health. all that and more is just ahead on "face the nation". >> brennan: good morning and welcome to "face the nation". the head of the world health organization said yesterday that it was impossible to predict which direction this corona virus now named co-vid 19 will take.

the death toll stands at over 1,660. they're evacuated americans from the diamond cruise ship. we're at the scene. >> it was supposed to be a scenic cruise around asia. instead, all passengers are in hazmat suits. >> the diamond princess has been docked for 10 days now. for many of the 400 americans on board, that ends today. packed their bags and ready to go home. the situation on board deteriorated this weekend as more than 350 concerned infections. of those, over 40 are americans. buses started arriving and taking the u.s. citizens to an airport in tokyo. they will fly out in the early hours of the morning. passengers who show any symptoms of the corona virus will not be allowed to fly.

but there's a catch. once home, everyone evacuated from the ship will have to undergo another 14 days of quarantine in the u.s. in wuhan, china, the crisis epicenter, methods being used to contain the virus. the front door of a family suspected to being infected is welded shut. emergency workers spry disinfected in offices as workers sit at computers. china has been criticized for lack of transparency in the initial stages of the outbreak. it's hoped that will change with the arrival of a team of experts from the world health organization. >> brennan: that's debra in yokahama. >> joining us is the director of infectious diseases. doctor, it's good to have you here. >> good to be here.

>> we were were hearing from evacuation of the americans on the cruise ship. more than 40 now. what can you tell us in terms of the americans exposed and infected. >> 40 of them have gotten infected. they're not÷÷9e+ózs@v?1-[ófr22y japan. peopleçziokñrñr areñi?3ta6í to evacuation plane. others will be evacuated to air force bases in the united states. if people on the plane start to develop symptoms, they'll be segregated on the plane. there's a firm plan with the 747 that's going to take the passengers there. if you want to stay in japan, your last khanls would be to get on the plane or stay there. when you come back to the united states in fort lee, they're subjected to 14 day quaurn taken. the reason for that and the degree of transmisibility on the cruise ship is akin to

being in a hot spot. >> brennan: for the americans infected, what does that mean? what's the state of their health hlg? >> you could have minimal symptoms and the possibility of transmitting it. you could be infected and have significant lung disease that requires hospitalization and series interveng. malaysian health authorities said there was an 83-year-old american on a different cruiseship that docked in cambodia. is this becoming a pandemic? >> a pandemic is when you have multiple countries with sustained transmission, from person to person. right now there are 24 countries in which there are over 500 cases. several of them are starting

to get to the second and third transmission. technically speaking it's not a global pandemic, but it's on the verge of that happening soon unless containment is more successful. >> brennan: debra said there's experts landing in china this weekend. americans will be among them. is there anyone from your -- what's the difference than if the cdc had been allowed in? >> we should not be talking about that, because the sensitivity of coming out ahead of the chinese of making an announce. >> brennan: on the program last week, americans were on the list. >> if he says it, they're on the list. >> brennan: what's the difference? what's the difference with your agency sending people than the cdc sending people? >> our cdc has the best epidemiologists in the world.

they can be helpful to the chinese. eyes, ears and boots on the ground. it's really helpful >> brennan: the who has been criticized perhaps being too careful around the chinese government, and part of the u.n. agency and receive funding. china has tremendous power over them, is that criticism fair? >> i don't know if it's fair or know. clearly the director of who. dr. ted rose is an outstanding person, and under difficult circumstances, doing a good job. >> brennan: the president has said that the virus could tick down in the warnler months ahead. he indicated president xi told him that? is that how it works? >> we don't know. but it's not unreasonable to say that influenza which peaks

in the winter, you expect by march, april and may to taper down, as well as corona virus. that's not an unreasonable statement. however, we do not know what this particular virus is going to do. it's a stretch to assume it's going to disappear with the warmer weather. it's completely unknown. >> brennan: you said you could have a vaccine within a year. how due speed up the timeline, and a manufacturer? >> first of all, margaret, that one year timeline will be the world's indoor record of getting a vaccine out to at least early deploy. you can't do better than that. if you go faster you're cutting dangerous corners. >> brennan: and no manufacturers yet? >> once you gate a vaccine that you know works the difficulty is having the companies take the risk of hundreds of millions of dollars to scale up to make it available.

>> brennan: so you're looking for a partner? >> i think we'll get them. i see the interest of companies that we didn't see with sars and other outbreaks. >> brennan: thank you for the update. appreciate it. we turn to another big story this week. attorney general barr's push back to perceived presidential interference into justice department cases. republican senator john kennedy joins us now from louisiana. senator, thaufrngt for being with us. >> thank you, margaret. >> brennan: the president says he has the legal right to intervene in criminal cases. do you agree? >> just because -- does the president have a right to tweet about a case? of course. just because you can doesn't mean you should. you can have a voice like mick jagger, but you wouldn't want

to start belting out honky-tonk woman in church. this is a case where tweeting this would not cause brain damage. roger stone is pretty good at bad decisions. nobody would confuse him with alexander hamilton. bill barr's justice department pursued him and convicted him. while the attorney general and others were trying to get the recommendations straight, the president tweeted, put the attorney general in an awkward spot, and helóh spoke out. i have no indicationkt doesn't.÷úg billq barra5hasñr s categorically and unequivically that the t( president has never tried s-a influence himq ina5 a criminal case. nor should he.çó look, this is myhcxperrqgce with bill barr.ñr h mature,okçóçóçó he's serious.i

he exercises powerñi fairlyxdxd intelligently. he's cqb withçóxd axdi] rationa mind. >> is it a good idea to get >> thi wwoin jce.? icularly when a public figure iinvolved. there are checks and balances and multiple layers of supervision. now, i -- it has been reported. i don't know if it's accurate.

it has been reported by two mainstream news organizations that the four front line prosecutors here said look, we're going to recommend 7 to 9 years for stone, and if you don't like it, they said this to their supervisors, we're going to quit and call a press conference. that's not the proper procedure. nobody is above the law, but nobody is beneath the law. mr. stone's status as a chuckle head is not a criminal act. >> brennan: whether the attorney general should have gotten personally involved. he said in an interview with abc that the u.s. attorney did consult with him before the filing, and then -- >> bill barr -- bill barr l thstice department did

was prosecute. the u.s. attorney question about the sentence. so barr says let's talk about, according to mr. barr's testimony. in the meantime, the frontline prosecutors went out on their own. now, i don't know exactly what happened. i just know what's been reported margaret. i can tell you if a staff -- one of my staff members came to me and said kennedy, i don't agree with your position on net neutrality, and if you don't change it, i'm going to quit and call a press preference 52-i tell you what i'd do. i'd say you have me confused with somebody who cares what you can't resign, because you're fired. >> brennan: do you want to call those prosecutors in for questioning? >> if they want to make a statement, that's fine. if the reported facts are wrong, they should say so.

the frontline prosecutor -- a frontline prosecutor on any case can't just go out on his or her own, particularly when it involves a public figure. now, bill barr -- >> brian: sorry, i want to get to another topic since i have you here. last time you were on "face the nation", you said if it could be demonstrated that the president asked for an investigation of a political rival, it would be in your words, over the line and probably impeachable. do you still stand by that? >> it depends on why he asked for it. i think what i said at the time -- i think what i said at the time was that if a president asked for investigation of a political rival because he's a political rival, that would be wrong. >> brennan: but i'm asking you if president trump was on

geraldo's program, and said juliagiuliani went to ukraine t investigate the bidens. does that meet the standard? >> the president asked for investigation of joe biden and his son and burisma. he didn't ask for an investigation of amy klobuchar and elizabeth warren. he asked why the president asked for investigation. hunter biden and burisma. these are the facts. i didn't nake this up. president obama put vice president biden in charge of the foreign affairs. in ukraine and china. and his son walks away with millions in contracts. does that make sense? >> brennan: i wanted to ask you about your standard. we have to leave it there. >> let me be clear. there's -- >> brian: i'm sorry.

>> asking for an investigation of corruption. >> brennan: we'll be back with amy klobuchar with a strong third place in new hampshire. she's going to join us from nevada.

>> brennan: and we're back with amy klobuchar. she joins us this morning from las lass. good to have you. >> great to be here margaret: >> brennan: do you take attorney general barr at his word that his personal interveengz in thvention in the had nothing to do with the president. >> i think he has to go under oath. i'm glad he will testify in front of the house judiciary committee. i hope he comes to the senate judiciary committee as well. that's where we get the answer. the president is constantly

tweeting out different requests of the justice department, and i think here where you've got a career prosecutor, and they got a conviction, and then they get under mined on the sentencing, and one of them leaves the justice department, the other one is transferred off the case -- that is not normal at all. you have to allow justice to have its course. that means no political intervention. >> brennan: we'll sf at happens senator. i want to get to your candidacy. you're a 2020 contender. you did well in new hampshire, and that's a different state, it's more diverse. that means you need to broaden support. how do you do that? >> i'm excited about our chances here. we just had a double digit poll. i also got the las vegas sun endorsement. we've had huge events here. over a thousand people in

reno. we're building up our staff all over the country in the super tuesday states. finally, i've gotten the resources i need. over $12 million in a little over a week since new hampshire. >> brennan: you have to play catch up there. >> for sure. i look at las vegas and nevada and see this. i'm a leader in tourism in the u.s. senate. big employers here. number two, i've been good on union issues and stood by working people. my grandpa, my dad, my mom. third, two women u.s. senators here. majority women in the legislature. they're used to elected women and proud of it. and ins is the moment i got to the senate i worked on immigration reform. ted kennedy asked me to work on it when george bush was president. we came close and didn't make it. i worked on it again with obama, and as president, i

would get it done. i'm having a lot of fun out here. and it's nice to be in the sun. >> brennan: again% of nevada's population was born outside of the u.s. fifth largest in the country. you're criticized because you're just now making changes to your immigration position, and you said -- you reversed position on whether english will be the national language. do you think that won you support? >> that wasn't this week. understand that everyone is following every twist and turn of the campaign. i said this way, way back, months and months ago in miami when asked. that was an early vote on english as the official language. a number of other democrats voted the same way, and all democrats eventually voted for it. i know that's not a good idea because it's hard to translate

brochures and and the like. and i worked on the latest version of the immigration bill that wasn't in there. >> brennan: on the specifics of what you would do differently. joe biden did an interview in which he was asked on the deportations of 3 million people during the obama administration. he says now that was a big mistake. do you believe it was a mistake for the administration to deport people who did not have criminal records? >> i think that went way too far, yes. i think you've seen a lot of that across the country. the question is what do we do going forward. to me the straight forward answer is comprehensive immigration reform. it would save $158 billion in 10 years. and part of that money when you talk about deportation could be used for asylum process, to improve that, part of it could be used to help

those northern triangle countries, and allow people to seek asylum in theountthe heinous practice of separating kids from their parents at the border. >> brennan: i want to ask you about race. michael bloomberg has come under crit zuchl for stop and frisk, and past comments viewed as insensitive to say the least. you said there's racial disparitys, and if you look at the black and white prison rates where you serve, there's disparitys. for you as a candidate, do you have regrets about your tenure? >> i think anyone involved in the criminal justice system, including me -- we know that it must be changed. i back then knew that there were issues. we actually saw a 12% reduction in african-american

incarceration rates during my eight years of being in office that handled 10 to 18,000 cases a year. i reduced discrimination. i reviewed all the dna serious cases to check to make sure there were not issues with those cases and diversified the office. what michael bloomberg did, stop and frisk is unconstitutional. i'm on your show answering tough questions. where is he? he just keeps running a bunch of ads. he'll have more ads during your show than i'm answering questions. he can't hide behind the money. he has to come on the shows and be on the debate show. i'm never going to beat him on theair airwaves.

>> brennan: thank you. we'll be right back with more "face the nation".
