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

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."

The impeachment trial continues after the Senate recessed for a dinner break. House impeachment managers will continue to deliver arguments.

The timestamp on security footage presented by House impeachment managers shows Vice President Mike Pence being evacuated from the Senate chamber at 2:26:02 p.m.

Trump, meanwhile at the White House, posted an attack on Pence to Twitter just two minutes earlier at 2:24 p.m.

"Mike Pence didn't have the courage to do what should have been done to protect our Country and our Constitution, giving States a chance to certify a corrected set of facts, not the fraudulent or inaccurate ones which they were asked to previously certify. USA demands the truth!" Trump tweeted, while the Capitol building was still under attack.

House impeachment managers in arguments on Wednesday sought to lay out a comprehensive timeline of the Capitol attack.
