Trump impeachment trial live updates: Biden says charge 'not in dispute' in 1st comments on acquittal

Lead House impeachment manager Rep. Jamie Raskin, D-Md., warned after an afternoon break that managers would soon present video footage viewers may find disturbing.

"I want to alert everyone there is very graphic violent footage coming, just so people are aware," Raskin said, after warning teachers earlier in the day and members of the public watching from home of the graphic footage to come.

He then handed the floor to Congresswoman Stacey Plaskett of the Virgin Islands to present the material.

The Senate has returned from a nearly 25-minute break to resume arguments from the House impeachment managers.

Rep. Madeleine Dean, D-Pa., one of the House impeachment managers momentarily lost her composure when talking about her experience in the Capitol during the Jan 6 riots.

"I stood with colleagues in the gallery above the House floor to observe the Arizona challenge. Moments later, police radios reported a breach of the Capitol grounds. Someone shouted up to us: 'duck,' then 'lie down,' then 'ready your gas masks.' Shortly after, there was a terrifying banging on the chamber doors. I will never forget that sound. Shouts and panicked calls to my husband and to my sons, instructions to flee and then the constant worrying of the gas masks filtering the air," Dean said. "The chamber of the United States House of Representatives turned to chaos."

Dean then criticized the speech made by Trump made to protesters right before they stormed the Capitol and she showed videos of how crowds of rioters reacted to the former president's remarks.

"He'd assembled thousands of violent people, people he knew were capable of violence, people he had seen be violent," Dean said. "They were standing now in front of him, and then he pointed to us, lit the fuse, and sent an angry mob to fight the perceived enemy, his own vice president and the members of Congress, as we certified an election."

Dean laid out a timeline of the events after the rally and emphasized that it was just one hour after Trump's speech that rioters breached the Capitol.

"At 1:10, the president ended his speech with a final call to fight and a final order to march to the Capitol. At 1:45, the president's followers surged past Capitol Police, shouting: "this is a revolution." Just after 2:10, an hour after President Trump ended his speech, the insurrectionist mob overwhelmed Capitol security and made it inside the halls of Congress. Because the truth is, this attack never would have happened but for Donald Trump. And so they came, draped in Trump's flag, and used our flag -- the American flag -- to batter and to bludgeon. And at 2:30, I heard that terrifying banging on House chamber doors," Dean said. "For the first time in more than 200 years, the seat of our government was ransacked on our watch."

The Senate is taking another roughly 15-minute break before continuing with arguments from the House impeachment managers.
