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

Rep. Joaquin Castro, D-Texas, continued to present the House impeachment managers' detailed timeline of the events at the Capitol and White House on Jan. 6, and said Trump did nothing to quell the protests even as those close to him asked for him to do so, suggesting Trump was the only one who could stop the siege. Instead, Castro said, Trump continued to incite the mob with tweets as violence was already underway.

"As this was unfolding and the crowd grew more violent, the president, of course, was not alone at the White House. And the people closest to him, his family, his advisers who saw this unfolding in real time, begged him -- implored him to stop the attack," Castro said, showing tweets and playing media appearances of both former and current Trump officials and lawmakers as they called on Trump, during the attack, to ask his supporters to go home.

Castro highlighted how Trump tweeted -- over an hour and a half into the attack at 2:24 p.m., while Pence was still sheltered inside the Senate chamber -- that Pence did not have "courage" to overturn the results as some rioters repeated the tweets on megaphones outside like marching orders. He then recounted how Trump tweeted at 3:13 p.m. to his supporters, still storming the Capitol, to "remain peaceful" and ended his tweet with a "Thank you!"

"Thank you for what? Thank you for shattering the windows and destroying property? Thank you for injuring more than 140 police officers?" Castro said.

The Texas representative also drew a clear distinction between Trump and Pence, despite his personal politics not matching to either.

"Mike Pence is not a traitor to this country. He is a patriot. And he and his family, who was with him that day, didn't deserve this, didn't deserve a president unleashing a mob on them. Especially because he was just doing his job," Castro said.

Rep. David Cicilline, D-R.I., argued that even as the violent protests broke out at the Capitol, Trump was not working to quell the violence or helping to prevent his supporters from rioting despite requests from members of his administration and Congressional leaders.

"This wasn’t partisan politics. These were Americans from all sides trying to force our commander-in-chief to protect and defend our country. He was required to do that. Now, the extent of how many people tried to reach the president, to get him to act, is not known. But what is clear, what we know without any doubt, is that from the very beginning, the people around Donald Trump lobbied him to take command," Cicilline said. "What’s also clear is what Donald Trump our commander-in-chief did in those initial hours to protect us -- nothing, not a thing."

Cicilline also criticized a call Trump made to Sen. Tommy Tuberville, R-Ala., during the riots asking him to object to more aspects of the election's certification rather than working to quell the ongoing violence.

"This was a breathtaking dereliction of his duty, ... of his oath as our commander-in-chief," Cicilline said. "These attackers stood right where you are. They went on that rostrum. They rifled through your desks and they desecrated this place. And literally, the president sat delighted -- doing nothing to help us, calling one of you to pressure you to stop the certification."

Minutes before the trial resumed, Republican Sen. Mitt Romney of Utah was seen talking to Capitol Police Officer Eugene Goodman.

Earlier, Romney -- and the public -- for the first time saw security footage presented by House impeachment managers of Goodman directing the senator -- often and publicly criticized by Trump -- away from the mob during the Jan. 6 attack.

Romney told reporters after seeing the video that he planned to thank Goodman.

"Obviously very troubling to see the -- the great violence that our Capitol Police and others are subjected to. It tears you at your heart and brings tears to your eyes. That was overwhelmingly distressing and emotional," Romney said.

As he was exiting the chamber for the dinner break, Romney said that he didn't know it was Goodman who helped him until the recording was played.

Goodman gained public notoriety for directing rioters away from the Senate chamber. He later escorted Vice President Kamala Harris to the inauguration.

Three members of Congress introduced a bill last month to honor Goodman with the Congressional Gold Medal "for his bravery and quick thinking."
