Danger To Lawmakers, Republican Reaction: Takeaways From Impeachment Trial Day 2

On Wednesday, House impeachment managers had senators riveted to disturbing new security camera video that showed just how close the rioters that breached the U.S. Capitol came to lawmakers in the House and Senate chambers.

Wednesday's images, from several angles outside the chambers and in hallways outside leadership offices, showed one Capitol police officer run past Utah Republican Sen. Mitt Romney and direct him to turn around and run, as rioters were closing in on that location just off the Senate floor.

Ominously, the video also showed staffers for House Speaker Nancy Pelosi move to hide behind a door in what is typically a secure office suite that minutes later was overrun by a mob that repeatedly tried to break down that same door.

Wednesday was the first of two days for the nine managers to present their case. After they finish on Thursday, the floor turns to Trump's defense.

One by one, the impeachment managers have been methodically re-creating a timeline. They went back months to try to show that former President Donald Trump not only incited rioters at the rally on Jan. 6, but that he laid the foundation to sow doubt in the outcome of the election that led to violence.

They argued that Trump repeatedly claimed any loss on Nov. 3 meant the election was "rigged" in rallies, tweets and speeches, and that he knew those who organized and attended the rally backed his effort to "stop the steal." The House members walked through how after various failed efforts to undermine the elections — including pushing state officials to overturn results, legal challenges and other attempts at intimidation — Trump was left with the focus on the last day, the day Congress met to count and certify the electoral votes.
