Biden remembered those who were killed and called for unity going forward.
Former President Donald Trump's historic second impeachment trial ended with a 57-43 vote to acquit in the Senate. He faced a single charge of incitement of insurrection over his actions leading up to the Jan. 6 riot at the U.S. Capitol.
Half of the four impeachment trials of U.S. presidents belong to Trump, and he is the only president to not have witnesses heard from at his trials.
Witnesses at the four impeachment trials of presidents:
Andrew Johnson in 1868: 41
Bill Clinton in 1999: 3
Donald Trump in 2020: 0
Donald Trump (after he left office) in 2021: 0

After an 11-hour scramble, the Senate has determined it will be calling no witnesses in Trump's impeachment trial.
The written testimony of Rep. Jaime Herrera Beutler, R-Wash., -- one of ten House Republicans who voted to impeach Trump -- was admitted into evidence, instead of moving further with the process for hearing from witnesses.
Neither the Trump legal team nor the House impeachment managers made any further motions. The parties mutually came to the agreement to admit Herrera Beutler's statement and not request further witnesses.
Closing arguments are underway, for which each side is allotted two hours.

The Senate has returned from a roughly one-hour recess after voting 55-45 to hear from witnesses in Trump's second impeachment trial.
Senate leaders were meeting during the break on drafting a resolution for calling witnesses following that unexpected vote. The resolution, ultimately, could call for no witnesses at all.
Before the chamber was gaveled back into session, Senate Majority Leader Chuck Schumer, Senate Majority Leader Mitch McConnell, House managers and Trump's defense team appeared to have an identical typed page -- with the parliamentarian studying the same sheet.
The decision to call witnesses revolves around the question of what Trump knew and when.
Lead impeachment manager Rep. Jamie Raskin, D-Md., had called to subpoena Rep. Jaime Herrera Beutler, R-Wash., who tweeted out a statement overnight reiterating comments she has made that House Minority Leader Kevin McCarthy tried to get Trump to call for a stop to the violence and that Trump told McCarthy, "'Well, Kevin, I guess these people are more upset about the election than you are.'"
Trump adviser Jason Miller has walked back and forth on Capitol Hill with a stack of papers he says is a witness list and has 301 names -- "SO FAR," the top page reads.
He told ABC News he’s not ready to share the whole thing yet because it’s a work in progress, but it signals Trump's team will match Democrats' call to have witnesses by potentially inundating the trial with them.
Miller's pacing comes as Republican Sen. Lindsey Graham has doubled down on his call for multiple witnesses -- if any are ultimately called with the resolution.
"It is my firm belief that the House Managers are trying to investigate the case AFTER it was brought to the Senate. It is better for the country to go to a final vote," Graham tweeted. "However, if the body wants witnesses, I am going to insist we have multiple witnesses."
Graham said the Senate could start with House Speaker Nancy Pelosi -- a sentiment floated by Trump defense attorney Michael van der Veen on the floor Saturday when he called for the trial to end "today."
The scramble for party leaders to work on a trial resolution for witnesses comes after the unexpected vote and call from House managers to subpoena Republican Rep. Jaime Herrera Beutler, who has said she has information on an intense call House Minority Leader Kevin McCarthy had with Trump during the Capitol attack, in which Trump sided with the mob while violence was underway.
