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

While House impeachment managers shared some of the most intense video and dispatch audio, much of which had never been seen publicly before. Reporters noted that senators on both sides of the aisle were listening and watching the videos intently.

Sen. Mitt Romney, R-Utah, didn’t move and watched intently when they showed the video of U.S. Capitol Police Officer Eugene Goodman directing him away from rioters.

When the new videos were playing, there were a handful of empty seats, Sen. Lindsey Graham, R-S.C., was one who was not at his desk. Some GOP senators opted to watch the proceedings from their cloak room. Reporters can't see them in there so it is unknown if they were watching it.

Rep. Eric Swalwell, D-Calif., continued presenting chilling security footage as part of House impeachment managers' case charging Trump with "incitement of insurrection" and also shared a personal text he sent while the building was under siege.

"Uncertain what would happen next, I sent a text message to my wife. 'I love you and the babies. Please hug them for me,'" Swalwell said. "I imagine many of you sent a similar message."

Security footage showed those who broke intro the Capitol overwhelmingly wearing Trump flags and merchandise and, separately, showed members of Congress being evacuated from their chambers.

"Throughout this presentation, we've been careful not to show where representatives got out," Swalwell added, "But that issue was under discussion by the insurrectionists themselves."

"One example comes from an FBI affidavit which stated the leader of a militia group known as the Oath Keepers received messages while at the Capitol. The leader was given directions to where representatives were thought to be sheltering and instructions to quote 'turn on gas, reel them in,'" Swalwell said.

Notably, video has surfaced showing Trump's longtime adviser Roger Stone in Washington on the morning of Jan. 6, flanked by members of the Oath Keepers militia group just hours before the deadly insurrection at the Capitol building.

Del. Stacey Plaskett, D-Virgin Islands, described rioters intent on finding and killing former Vice President Mike Pence and House Speaker Nancy Pelosi during the violent protests.

"They were talking about assassinating the vice president of the United States. During the course of the attack, the vice president never left the Capitol, remained locked down with his family -- with his family -- inside the building. Remember that as you think about these images and the sounds of the attack," Plaskett said. "Vice President Pence was threatened with death by the president’s supporters because he rejected President Trump's demand that he overturn the election."

Plaskett showed videos of rioters running through the hall screaming "Nancy, where are you?" The House managers also showed security video showing staffers in Pelosi's office running into a conference room, where Plaskett said they barricaded themselves in an inner chamber. Just seven minutes later, she said, the video shows rioters entered the speaker's office, where they destroyed property and searched for Pelosi.

"The vice president, the speaker of the house, the first and second in line to the presidency, were performing their constitutional duties, presiding over the election certification. And they were put in danger, because President Trump put his own desires -- his own need for power -- over his duty to the Constitution and our democratic process," Plaskett said. "President Trump put a target on their back and his mob broke into the capitol to hunt them down."

Congressman Stacey Plaskett, D-Virgins Islands, presented disturbing evidence that had not been made public before of security footage inside the Capitol on Jan. 6 and of audio of 911 calls from law enforcement officers in distress.

"They're throwing metal poles at us," one officer said on a 911 dispatch. "13:49 hours. Declaring it a riot," said another.

"At 12:53 p.m., senators, members of Congress, Vice President Pence were in their respective chambers. Outside rioters, including some linked to the Proud Boys, broke through the outer barricade surrounding the lawn of the Capitol," Plaskett said, laying out the timeline of the attack.

She played "never-seen-before" security footage from inside the Capitol around the time Vice President Mike Pence was whisked out of the Senate chamber which showed rioters ramming through the doors of the Capitol, shattering glass and overcoming Capitol Police.

She said rioters were "within 100 feet" from the vice president and that it wasn't until 2:26 p.m. when he was evacuated.

"While Vice President Pence was being evacuated from the Senate chamber, rioters were, at that time, breaking into the Capitol," Plaskett said. "When I first saw this, that was created for this, I thought back to Sept. 11," she added of the video exhibits.

Plaskett went on to show security footage of Officer Eugene Goodman directing Republican Sen. Mitt Romney of Utah to turn around in order to get to safety to avoid the mob heading straight in his direction.

She said it was clear Pence was a target "for his patriotism" -- for following through with his duty to certify election results -- and had rioters gotten ahold of him, they would have hurt or killed him, she said, citing their own chants of, "Hang Mike Pence."
