Jan 6. Hearing Live Updates and Analysis: Committee Lays Out Case Against Donald Trump

U.S. Capitol Police and loved ones of officers who died after the Jan. 6 riot watched graphic video footage of the attack in the hearing room Thursday night with their arms around each other.

Officer Harry Dunn, who testified under oath at a previous hearing, could be seen comforting Sandra Garza, the long-time partner of Capitol Hill Police Officer Brian Sicknick, who died shortly after the riot.

Also in the audience of the hearing Thursday is a group of Democratic lawmakers who call themselves the “gallery group.”

These lawmakers were briefly trapped in the gallery of the House chamber when the Capitol was breached and the doors in the chamber were locked. They crawled over bannisters and helped each other to get to an unlocked door and escape.

Rep. Dean Phillips (D., Minn.) tweeted a photo of the ones in attendance.

“It’s just shocking and infuriating, a year and a half later,” said Mr. Phillips, during a break in the hearing.

He praised Republican Rep. Liz Cheney of Wyoming, the vice chair of the committee, for her opening statement, calling her a “national savior.”

“The narrative that she just presented was crisp and clear, and unambiguous, and extremely courageous,” he said.

Mr. Phillips said he hoped Americans were paying attention. “God I hope so,” he said.

Rep. Pramila Jayapal (D., Wash.) broke down in tears when reporters asked her how it felt to watch the video after being trapped with other lawmakers in the House gallery as the mob tried to break in.

“I never imagined that in doing our jobs, that we would not be safe to do our jobs, and that we would feel so helpless in that moment to protect our democracy,” Ms. Jayapal said, her voice shaking.
