And now a new day at the white house. There's a live look where Joe Biden will begin his first full day as America's 46th president. The inauguration unusual in so many ways, everyone in masks surrounded by troops at a capitol still scarred by that siege two weeks ago. Biden urged empathy, pledged to put his whole soul into uniting our country and promised action starting with the pandemic. Biden's new chief medical adviser Dr. Anthony Fauci will join us live later this morning. Chief white house correspondent Cecilia Vega starts us off. Reporter: Good morning to you. After a nearly 50-year-long political career, two failed presidential runs before this one, Joe Biden is finally waking up right here behind me in the white house with the job that he has always dreamed of, president. This morning, Joe Biden waking up in the white house after that celebration overnight, fireworks lighting up the nation's capital. It followed a swearing in like none this country has ever seen. Surrounded by their families, president Biden and vice president kamala Harris making history, three past presidents there to witness it. One glaringly absent. The crowd small, socially distanced and masked. The ceremony held at the very site of that deadly insurrection just two weeks ago, the day both solemn and celebratory. I, kamala devi Harris, do solemnly swear. Reporter: Harris being named vice president sworn in by another first, justice Sonia Sotomayor, the first Latina on the supreme court. So help me god. Reporter: Sharing a fist bump with another history maker, former president Barack Obama and a moment with Mike pence, the man she replaced. Joe Biden then taking the oath that he's dreamed of his entire life placing his hand on the bible that's been in his family for more than 100 years. I Joseph robin internet, Biden, Jr., do solemnly swear. I, Joseph Robinette Biden Jr., do solemnly swear. That I will faithfully execute. That I will faithly execute. The office of president of the United States. The office of president of the United States. So help you god. So help me god. This is America's day. This is democracy's day. A day of history and hope, of renewal and resolve. We've learned again that democracy is precious, democracy is fragile and at this hour, my friends, democracy has prevailed. Reporter: And calling for unity against the challenges facing this country. To overcome these challenges, to restore the soul and secure the future of America requires so much more than words. It requires the most elusive of all things in a democracy, Reporter: In his 21-minute address, Biden demanding an end to what he called an uncivil war pinning red against blue. On this January day, my whole soul is in this, bringing America together, uniting our people, uniting our nation and I ask every American to join me in this cause. Reporter: He never mentioned Donald Trump by name, but he did speak directly to the 74 million Americans who voted for him. To all those who did not support U. Let me say this, hear me out as we move forward. Take a measure of me and my heart. I promise you, I will fight as hard for those who did not support me as for those who did. Reporter: Saying the only way to get through these struggles is to get through them as one. We have never ever ever failed in America when we acted together. Reporter: A message echoed over and over from this rare joint appearance from three former presidents. Everybody needs to get off their high horse and reach out to their friends and neighbors. Reporter: To the youngest ever inaugural poet and her poem "The hill we climb.." We will rebuild, reconcile and recover in ef a known nook of our nation and our people diverse and beautiful will emerge battered and beautiful. Reporter: Former president trump throwing his own send-off at joint base Andrews instead. So have a good life, we will see you soon. Thank you. Reporter: But now it's down to business for president Biden who made this promise overnight. There are moments in our history when more is asked of us as Americans, the question is, are we up to it? Will we meet the moment like our forbearers have? I believe we must and I believe we will. Thank you for this honor. I will give my all to you. May god bless America and may god protect our troops. Reporter: A promise to all Americans there. Now, Joe Biden has been in the oval office countless types before but this is his office now at least for the next four years and let me show some of the personal touches he's made. A bust there of the Latino civil rights leader Caesar Chavez. It was a request directly of the Biden administration transition team. A portrait of fdr, a clear nod to another president who helped the country face during a moment of crisis and behind the resolute desk, George, a number of Biden family photos including one of his late son beau right there who clearly was on the president's mind every step of the way yesterday. Always top of mind and seemed like everything they were doing at the white house yesterday after that inaugural address was designed to signal a new start including that first white house press briefing last night. Reporter: First white house press briefing, everything about it was different. Press secretary Jen psaki said she will share the truth even when it is hard to hear, a quote. There were questions about answers in policy and something else that's new, even people who have to come on to the white house ground have to get tested now for covid every day. Everyone wearing masks all the time. Thanks very much.
