norah. >> o'donnell: nancy cordes at the white house, thank you. now to some sad news to report.r senator bob dole revealed today that he has stage four lung cancer and will begin treatment on monday. dole is 97 years old. he suffered serious wounds in world war ii, then served kansas in the house and senate for more than 35 years. remember, he ran against bill clinton as the republican nominee for president in 1996. and tonight, nasa is celebrating a big success-- the landing of its most-advanced mars rover. "perseverance" has already sent back pictures and will soon begin its mission to answer a question that scientists have pondered for ages. here's cbs' carter evans. >> touchdown confirmed. ( cheering ) "perseverance" safely on the surface of mars. >> reporter: "perseverance" stuck the landing. ( cheering ) these new images are proof of life for a mission now searching for life on mars. >> liftoff! >> reporter: the seven-month journey, leading to a frantic final seven minutes. the rover hurtling towards mars at 12,000 miles per hour, its heat shield surviving temperatures hot

let's bring in cbs' nancy cordes now. nancy, that question- and-answer portion of the trial has concluded. what did we learn from it? >> reporter: well, first off, we learned how some senate republicans are likely to vote. senator tim scott, from south carolina, for example, as part of his question, described the proceeding as a "political show trial." that's a pretty good hint that he is leading towards acquittal. we also learned the president's lawyers haven't spent much time, if any, talking to their client, because not only did they have no idea what actions he took-- if any-- to stop the violence once it started on january 6, but they also couldn't answer that question about why mr. trump was still tweeting criticisms of his own vice president that day, even after he had been told the v.p. had to be evacuated from the senate chamber because the mob was closing in, norah. >> o'donnell: and, nancy, it's unlikely at this hour that there are going to be 17 republicans who will vote to convict trump. so what does that say

let's bring in our panel of nancy cordes, major garrett, and ed o'keefe. and, nancy, there were some-- there were some claims made that i think we're going to have to fact check, that were just made by the president's defense attorney. >> sure. you know, starting with the fact that he said that the president never-- never encouraged violence, that he never knew that this could possibly happen, when what we've seen laid out by the house impeachment managers is that the president often embraced his supporters who were violent. he reretweeted them. he invited them to the oval office. he often held meetings with them at the white house, as major well knows, and often turned a blind eye to that violence, even when supporters of his, for example, concocted a plan to kidnap the governor of michigan. the fact that this-- this defense was so brief, norah, was really striking, because they basically ignored enormous swaths of the prosecution's case. they never addressed things like why he so often condoned violent groups or why he pushed a conspiracy for months that

let's bring in cbs's nancy cordes who was there at the capitol during the assault. ncy, it was stunning to see that video, to see just how close those rioters came to the senators. >> reporter: right, and really hard to watch, the security video and bodycam video of these police officers being pummeled with flagpoles and fire extinguishers and bullhorns and really, anything these rioters could get their hands on. and that was meant to be tough to watch, especially for the senators who were sitting there as part of the jury today. the message was, look at what these men and women went through, because of the lies that the president told, that this crowd believed. and look at what could have happened to you, senators, if these men and women hadn't laid down their lives to protect you. >> o'donnell: on that very point that the senators lives could have been in danger, that image of course of that man in full tactical gear holding the plastic zip ties that could have been used as handcuffs on the senators-- could any of evidence or the images shown convince those 17 repu

i want to bring in now cbs' nancy cordes. and, nancy, those impeachment managers branded the former president as a clear and present danger to american democracy. i guess the question is did they make their case and were they able to convince 17 republican senators? >> reporter: norah, i think it was enough to convince some of them, but based on what we're hearing from republicans after this trial broke up for the day, 17 is going to be pretty difficult. marco rubio of florida said impeachment is inappropriate because president trump is a private citizen now. roy blunt of missouri said his view is unchanged. john cornyn of texas told reporters "i have concerns about impeaching a former officeholder." these are the kinds of republicans who would need to be on board in order to get a two- thirds vote to convict. that's a vote that would be highly unpopular with their base, and at this point, at least, it appears they're leaning against it, norah. >> o'donnell: and looking ahead to tomorrow, the president's legal team making thei

cbs's nancy cordes reports from the white house. >> the federal government has to chip in, make sure we get this done. >> reporter: president biden pushing his relief bill argues it will help schools reopen sooner. >> the goal will be five days a week. >> reporter: that goal is more ambitious than the 100-day goal the white house laid out just last week, of in-person schooling at least one day a week for children in k-8. >> that's not true. it was a mistake in the communication. >> reporter: white house press secretary jen psaki. >> certainly when i said one day a week it was our floor, not our ceiling. >> reporter: one key will be getting teachers their shots. >> in-person teaching must be safe for everyone. e a blic pushconnecticut today. the president supports prioritizing teachers. >> we should move them up in the hierarchy. >> reporter: it is a view he shares with 76% of americans. but right now the white house is leaving it up to the states. can't you mandate that states prioritize teachers? >> we can provide federal guide lines, which is exactly what we have done. but that is

here's cbs' nancy cordes. >> america is back. >> reporter: in his first, virtual, foreign address,t bide president biden made this vow to european partners: >> an attack on one is an attack on all. >> reporter: he said the trump era had strained the trans-atlantic alliance. >> many countries owe us a tremendous amount of money. >> reporter: and he promised to begin mending fences. >> the united states is determined to earn back our position of trusted leadership. >> reporter: as proof, he pledged $4 billion to covax, global vaccine initiative. and the u.s. officially rejoined the paris climate agreement today, a move hailed by u.s. allies. >> it's great, by the way, that joe has brought the united states back into the paris climate change accord. >> reporter: mr. biden took a tough stance on russia today, accusing it of undermining democracy itself. >> that's why addressing recklessness, russian recklessness, and hacking into computer networks in the united states and across europe and the world, bcritoot our collective bide standing by his embattled pick for white house budget director

let's bring in our chief white house correspondent, cbs's nancy cordes.there at the capitol on january 6. we really got a preview today of what we're going to hear in these coming arguments. >> reporter: right. it's clear that the house impeachment managers want these senators to remember the full horror of that day, when they were hiding below their desks instead of sitting at them, like they are during this trial. they're trying to argue that this is a assault on democracy itself, and that these senators have a duty to posterity to repudiate it, even if it means taking a tough vote. as for the president's lawyers, they say, yes, what happened at the capitol, the bloodshed, was terrible, but the president, they argued, just didn't have anything to do with it. they say when he told his supporters repeatedly to fight, he didn't mean it literally. >> o'donnell: and what about president joe biden? much of his agenda now stalled as this impeachment trial is happening. what is the president keeping busy with? >> reporter: well, he says he's got a job to do. he

norah. >> o'donnell: nancy cordes, thank you.r into the pandemic, health care workers are still clamoring for n95 masks, and tonight, federal agents have seized a warehouse full of them-- all fake. turns out, millions have been sold to unwitting hospitals around the country. cbs's jeff pegues with more on the investigation. >> reporter: today, l agents seized one million counterfeit masks in this western maryland warehouse. what they uncovered is pallets full of fake n95 masks that were headed to the front lines in the battle against covid-19. washington state's hospital system spent $8 million on n95 masks that turned out to be fake. they actually passed their inspections process because they looked like the real thing. >> they are really, really good fakes. they look, they fit, they breathe, they wear like a real 3m, n95 mask.n cent weeks, proxim11 milon counterfeit n95 masks have been seized in five states, and while the packaging says that these are the coveted 3m, n95 >> reporter: if you put them side-by-side, the only way t

cbs' nancy cordes reports tonight from the white house. >> reporter: president biden returned from camp david to a city still shaking off the specter of impeachment. >> he's not guilty as charged. >> reporter: the senate failed to meet a two thirds threshold this weekend to convict his predecessor, but seven republicans who voted with democrats are now facing their own reckoning. >> mr. cassidy, guilty. >> reporter: senator bill cassidy was censured by louisiana's republican party on saturday. tonight north carolina's republican party voted to censure senator richard burr. >> i think that's an appropriate act. >> reporter: dan bishop supported the move. >> senator burr senator burr has served north carolina in congress for 25 years. doesn't he have the right to cast a vote as he sees fit? >> i like senator burr, i'm friendly with senator burr but this was an error and the friendly w republican party is correct in my judgment to express that view. >> reporter: mr. trump, who waved to supporters in west palm beach today, is still facing an election-related investigation in georgia and a f

major garrett, and chief white house correspondent nancy cordes are with us here again. but the fact of it is still reverberating. even today, the capitol is a fortress. that security costs tens of millions of dollars. you have still got many national guard members who are there at the capitol, and that people are still suffering emotionally and physically from what they went through. and they're going to juxtapose that against what we heard, if anything, from president trump about this. has he shown any regret, any remorse? "maybe i should have toned things down. maybe i shouldn't have told thosealize for so many months." spoiler alert: he hasn't said anything like that. to this point he has not officially conceded the election. he never said out loud, "i lost, president biden won." he skipped town before biden was even inaugurated. so they are going to argue that that is further evidence that what we saw on january 6 was exactly what he wanted to happen. >> o'donnell: some of that never-before-seen videos showed senators literally running for their lives. >> reporter: r

nancy cordes is on capitol hill. nancy what can we expect to see and hear today?he president, the former president incited the insurrection we saw here on january 6th. they're going to make that case using mr. trump's own tweets before, during and after the assault, and the many speeches he gave in the months leading up to the assault in which he insisted that the election had been stolen from him. and they're going to play more of that graphic video that we saw yesterday, juxtaposing mr. trump's words with the actions of his followers. now, mr. trump's lawyers are going to have a couple of days here to regroup after republicans slammed their performance yesterday. still, just six republicans voted with democrats to allow this trial to move forward. louisiana's bill cassidy was one of those republicans. he said the house impeachment managers changed his mind and convinced him at least that this trial is constitutional. >> president's trump team was disorganized. they did everything they could but to talk about the question at hand, and when they talked about it, t
