>> our house! >> reporter: once inside, emboldened, telling stunned officers that president trump had sent them to do this. >> you are outnumbered. there's a [ bleep ] million of us out there and we are listening to trump, your boss. >> knock, knock. we're here. >> is this the senate? >> reporter: and the chilling search for speaker nancy pelosi. >> where the [ bleep ] is nancy? >> reporter: inside the senate chamber -- insurrection. >> there's got to be something in here we can [ bleep ] use against them. >> i think cruz would want us to do this, so -- >> yeah, absolutely. >> i think we're good. >> reporter: for the first time, we see a lone capitol police officer in the chambers. >> okay, i just want to let you guys know, this is, like, the sacredest place. >> hey, no, i'm going to take a seat in his chair, because mike pence is a [ bleep ] traitor. >> reporter: the qanon follower, jacob chansley, leaving that ominous message on mike pence's desk. >> it's only a matter of time. justice is coming. >> reporter: "it's only a matter of time. justice is coming." and another newly released video shows a capitol police officer wearing a maga hat, begging rioters to help him get to the officers he says are trapped inside the capitol. >> they can stay there, i just need to get the other officers out. >> reporter: the two men guide the officer into the capitol building -- >> clear a hole! let them leave. >> reporter: the crowd letting the officers pass through safely. and with news that at least one off-duty national guardsman has been arrested for storming the capitol and other veterans part of the siege, all of the guardsmen are being vetted for possible insider threats. >> the fbi is part of it, the secret service is part of it and once they are certain that there's no insider threat, then that soldier, guardsman or airman is given a credential. >> reporter: meanwhile, federal law enforcement continues to round up rioters. jon schaffer, an indiana heavy metal musician, turning himself in sunday. a former acquaintance of riley june williams, authorities say that's her in the green t-shirt, told them williams was trying to sell a computer taken from nancy pelosi's office to russian intelligence. authorities say she's still on the run. and couy griffin, a new mexico county commissioner who leads the group cowboys for trump, promised in this meeting to return to d.c. with guns. >> i'm going to leave either tonight or tomorrow. i've got a .357 henry big boy rifle, lever-action, that i've got in the trunk of my car. >> reporter: the fbi says griffin was, indeed, found blocks from the capitol on sunday, with his guns. and wesley allen beeler was arrested friday with a gun in his truck at a security checkpoint. he was trying to get to work at a security job and forgot to leave his gun at home in virginia. >> so, let's bring in martha raddatz back with us again tonight. martha, i know hundreds of thousands of tips have now come in and what's also notable, many of the people actually tipping authorities off. >> reporter: david, there have been more than 200,000 digital tips and many from family and friends of those who stormed the capitol. and as you said earlier, david, the rehearsal will continue. we are surrounded by armed troops here on the ground, but several thousand ceremonial troops took part in that inauguration rehearsal today and it will go on as planned. david? >> and you'll be right here with us all week long. martha, thank you. meanwhile, president trump tonight with 36 hours left in office. what our team is now learning about how many pardons are still expected and will there be a self-pardon or pardons for his children? here's our chief white house correspondent jonathan karl. >> reporter: while president trump was once again nowhere to be seen, first lady melania trump today offered her farewell message to the nation. >> my fellow americans. >> reporter: in the pre-recorded video, she seemed to allude to the attack on the u.s. capitol by supporters of her husband. >> be passionate in everything you do, but always remember that violence is never the answer. and will never be justified. use every opportunity to show consideration for another person. >> reporter: but mrs. trump will be the first first lady in modern history not to invite her successor to the white house before the inauguration, denying a courtesy to dr. jill biden that michelle obama extended to her. of course, president trump isn't extending that courtesy to joe biden, either. some of trump's advisers have been pleading with him to at least call biden and to leave him a note in the oval office, a longstanding tradition for outgoing presidents. shortly after taking office, trump showed david the note barack obama left him. >> and this was the letter given to me by president obama. >> we saw that image of him, >> we saw that image of him, the final morning that he was here, putting the letter on the desk. >> which was, i won't show it to you, read it to you, but just a -- a beautiful letter. >> is there a line you can share that struck you most? >> there were numerous lines, so well-written, so thoughtful. >> reporter: george h.w. bush famously left bill clinton a note, saying, quote, "you will be our president when you read this note. your success is now our country's success. i am rooting hard for you." trump is instead planning a farewell ceremony for himself at joint base andrews, with great military fanfare. then he'll board air force one for the last time and head to mar-a-lago, where moving trucks were spotted today. before he goes, trump is expected to announce about 100 pardons. but sources tell abc news, the president is not expected to pardon himself or any members of his family or any close associates. and then there's the matter of his impeachment trial. who will lead his defense is up in the air. it had been expected to be rudy giuliani, but giuliani told abc over the weekend that he's out, because he, too, spoke at the rally before the riot. >> let's have trial by combat! >> reporter: giuliani says that makes him a potential witness. >> all right, so, let's get right to jon karl, live at the white house tonight. and jon, you showed that moment and boy, it took me back. in the oval office, right off the last inauguration. president trump was really so proud of that letter president obama had left for him. but i guess the question, jon, is that tradition of leaving letters for the next president now over? >> reporter: well, we'll see, david. i can tell you that several people close to president trump have urged him to leave a letter to president-elect biden. whether or not he does remains to be seen. but this much is already clear, donald trump will be the first president, the first outgoing president in more than 150 years, not to attend the inauguration of his successor. >> in 150 years. all right, jon karl, our thanks to you, as well, tonight. in the meantime, president-elect joe biden tonight, what he now plans to do on day one of his presidency. here's mary bruce on that. >> reporter: as washington prepares to usher in the biden era, with less than 48 hours to go, the president-elect is putting the finishing touches on his big speech. >> sir, how's the speech writing going? have you finished your speech? >> good. >> reporter: biden, spending this martin luther king holiday packing boxes at a food pantry in wilmington with the soon to be first lady, jill biden. his team is laying out the plan for day one. biden expected to sign roughly a dozen executive orders, undoing some of donald trump's most controversial moves. he will immediately rejoin the paris climate accord, reportedly cancel the keystone pipeline and will reverse the so-called muslim travel ban. and take the first step in his fight against covid -- mandating masks on federal lands and extending the pause of student loan payments. but biden's big ticket items, like that massive $1.9 trillion stimulus plan, will require congressional approval. >> there is a lot to do. some would say that ours is an ambitious goal. but we do believe, with hard work and with the cooperation and collaboration of the members of the united states congress, that we can get it done. >> reporter: kamala harris will make history this week as the first black woman and the first asian-american sworn in as vice president. administering the oath, justice sonia sotomayor, the first woman of color on the supreme court. and it will happen on the same spot where that mob of trump supporters stormed the capitol. harris today asked if she had any security concerns. >> i am very much looking forward to being sworn in as the next vice president of the united states, and i will walk there, to that moment, proudly, with my head up and my shoulders back. >> and she will make history. mary bruce, president-elect joe biden's inaugural address will also be historic, they all are. but this one will be delivered amid a pandemic, this economy, a racial reckoning and just days after the deadly riot. so, what are you learning tonight? what does he hope to accomplish before the american people on wednesday? >> reporter: well, david, there's no question, this will be the most consequential speech of biden's life. he will be speaking to millions of americans who are hurting, hard-hit financially and grieving, to many who are just plain angry, including many of president trump's supporters. he'll be reaching out directly to them, too, as biden outlines his vision and plan to try to unite and heal this country. david? >> all right, mary bruce, with us all week, as well. thank you, mary. and now to the coronavirus. the first case reported in this country was one year ago this week. and tonight, the nation now nearing that milestone, 400,000 lives lost. and news on the vaccination effort. here's abc's steve osunsami now. >> reporter: this week now marks a whole year since covid-19 first appeared in this country, when the president was saying the disease would be handled. >> we have it totally under control. it's one person coming in from china and we have it under control, it's going to be just fine. >> reporter: but the new numbers tonight aren't fine. the number of americans killed by the coronavirus is now nearly 400,000. and the cdc warns that another 100,000 could die in the next month. the disease is overwhelming funeral homes tonight in los angeles county. the cemeteries can't keep up. manuel lopez marquez died last week, but his family says they might not be able to bury him for another month and a half. >> when we called the cemetery, we were 102 on the waiting line. and it took about six to seven hours to get through to the mortuary. >> reporter: in hard-hit communities, like this one in yuma, arizona, they're waiting on new supplies of the vaccine, because they don't have enough doses for everyone who is eligible to get one. pat parker in texas is one of the many who says she's desperate to get the shot. >> i don't want to die of covid. it's that simple. i don't want to die of covid. >> reporter: in california, they're working through a setback. more than 330,000 doses are on hold until health officials can figure out why a small number of people at a single vaccination center suffered possible allergic reactions after getting the shot. >> the risk, which is so small of a severe allergic reaction, particularly in somebody who's never had a history, really is minute compared to the risk of just having covid. >> reporter: diana says it could have been something else that caused her reaction and says she doesn't want other americans to avoid the vaccine. >> i do have a lot of friends that have heard my story and still went and got their vaccine and i think that's amazing. >> reporter: health officials here at the cdc are now tracking variants of the coronavirus that are more contagious. they point out that the vaccine works against all of this, which is why they underline that an overwhelming number of americans need to get vaccinated. david? >> all right, steve osunsami. steve, thank you. overseas tonight, vladimir putin's fiercest critic, alexei navalny, who was nearly poisoned to death, returning to russia and immediately detained. well tonight, his message, and james longman now from london. >> reporter: a dangerous gamble for one of vladimir putin's most vocal critics. and he was arrested minutes after arriving in moscow, kissing his wife good-bye. and tonight, alexei navalny has now been detained for at least 30 days, prompting outrage around the world. with his supporters outside, russia's leading opposition activist was brought before a hastily-arranged hearing at the police station itself. the judge ruling navalny violated parole for an earlier charge. he spoke today in the court, saying, "you just tore up all the criminal procedure laws and threw them in the trash." navalny nearly died last year after being poisoned with the extremely toxic chemical weapon novichok. he fell ill on an airplane, blaming the kremlin for the attack, something they deny. he had this message for his supporters. "don't be afraid. take to the streets. don't go out for me. go out for yourself and your future." navalny is being held until a parole hearing later this month, which could mean years of additional jail time. david? >> all right, james longman in london tonight. james, thank you. and when we come back here, the arrest at a major american airport. the man allegedly hiding there for three months. llegedly hidin llegedly hidin for three months. oh i got to tell everyone. hey, rita! you now earn 3% on dining, including takeout! bon appetit. hey kim, you now earn 5% on travel purchased through chase! way ahead of you! hey, neal! you can earn 3% at drugstores. buddy, i'm right here. why are you yelling? because that's what i do! you're always earning with 5% cash back on travel purchased through chase, 3% at drugstores, 3% on dining including takeout, and 1.5% on everything else you buy. chase. make more of what's yours. next tonight next tonight here, the man arrested for allegedly living at chicago's o'hare airport. prosecutors say aditya singh was too afraid to fly back to los angeles because of the coronavirus and that he'd been living inside a secure area for three months using an airport worker's misplaced credentials. when we come back here tonight, the nfl's two oldest quarterbacks making history, and now the moment after the game. now the moment after the game. e. ♪ here's to the duers. to all the people who realize they can du more with less asthma thanks to dupixent, the add-on treatment for specific types of moderate-to-severe asthma. dupixent isn't for sudden breathing problems. it can improve lung function for better breathing in as little as 2 weeks and help prevent severe asthma attacks. it's not a steroid but can help reduce or eliminate oral steroids. dupixent can cause serious allergic reactions including anaphylaxis. get help right away if you have rash, shortness of breath, chest pain, tingling or numbness in your limbs. tell your doctor if you have a parasitic infection and don't change or stop your asthma treatments, including steroids, without talking to your doctor. are you ready to du more with less asthma? talk to your asthma specialist about dupixent. if your financial situation has changed, we may be able to help. - i'm norm. if your- i'm szasz.ituation has changed, [norm] and we live in columbia, missouri. we do consulting, but we also write.
