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

ABC News' Chief White House correspondent Jon Karl talked about the video released Wednesday showing former Vice President Mike Pence being evacuated from the Senate floor during the violent riots on Jan 6, after protestors made threats on his life.

"They wanted to get there, they wanted to stop the certification and they wanted to get at Mike Pence because they saw him as a traitor because he was unwilling to do Donald Trump's bidding at this," Karl said.

Karl also noted that just two minutes before the video of Pence being evacuated from the Hill, former President Donald Trump had tweeted about him lacking the courage to change the results of the election.

"I really think it's one of the most damning pieces of evidence we saw today, on a day when there were obviously many damning pieces of evidence," Karl said.

ABC News' Senior National Correspondent Terry Moran said the House managers' arguments were "intense," and that they had clearly prepared the case they presented in the Senate chamber.

"Their presentation was both methodical and infuriating. It was organized and terrifying at times," Moran said.

Moran added that the timeline that the House managers presented spanned from well before the election to the Capitol riots on Jan. 6.

The Senate has recessed for the day after roughly eight hours of arguments from House impeachment managers.

The House managers will continue laying out their case charging Trump with "incitement of insurrection" at noon on Thursday.

Trump's legal team will have its turn to respond to the House impeachment managers' arguments on Friday and, if more time is needed, on Saturday.

Moments before the Senate was to adjourn for the evening, there was confusion in the chamber as Sen. Mike Lee, R-Utah, challenged comments made by Rep. David Cicilline, D-R.I.

Lee said that the account of a phone call Cicilline described was not "factual," and argued that as the witness he should be able to have the remarks stricken from the record.

However, the senators are not supposed to speak on the floor during impeachment proceedings. If they have questions, they are supposed to be submitted in writing. Lee's request prompted confusion on the dais and from the floor where several senators were unclear what was happening.

Rep. Jamie Raskin, D-Md., was acknowledged and returned to the microphone to withdraw that portion of Cicilline's remarks.

"The impeachment manager Mr. Cicilline correctly and accurately quoted a newspaper account which the distinguished senator has taken objection to, so I am happy to withdraw it, but on the grounds that it is not true -- we will withdraw this evening and without any prejudice to resubmit it, and we can debate if we need to, but this is much ado about nothing because it's not critical in our case."
