Capitol Police officer Caroline Edwards told lawmakers that her patriotism was called into question as she pushed back against rioters, sustaining a serious head injury in the process.

"I was called Nancy Pelosi's dog, called incompetent, called a hero and a villain," Edwards testified. "I was called a traitor to my country, my oath and my Constitution. In actuality, I was none of those things."

She continued, "I was an American standing face to face with other Americans asking myself how many times -- many, many times -- how we had gotten here."

Edwards recounted her own grandfather's experience fighting in the Korean war, telling lawmakers she will "gladly sacrifice everything to make sure that the America my grandfather defended is here for many years to come."

Among several clips of taped testimony with Trump aides, Rep. Liz Cheney, R-Wyo., played one of Jared Kushner telling the committee that he dismissed White House counsel Pat Cipollone's "multiple" threats to resign when asked if he was aware on any instances.

"Like I said, my interest at that time was on trying to get as many pardons done, and I know that he was always, him and the team, were always saying oh we are going to resign," Kushner said. "'We are not going to be here if this happens, if that happens' … . So, I kind of took it up to just be whining, to be honest with you."

Cheney slammed Kushner's response.

"Whining," she repeated.

"There is a reason why people serving in our government take an oath to the Constitution," she said. "And that oath must mean something."

The House select committee played a 10-minute video compilation including never-before-seen footage of rioters violently breaching the Capitol overlaid with law enforcement officers calling for backup, and Trump calling the crowd "loving."

In chronological order, the video followed the timeline of the day: from Trump speaking at his "Save America" rally to the joint session of Congress being gaveled in -- leading up to rioters clashing with police and storming the Capitol, prompting lawmakers to take cover.

Capitol Police Officer Harry Dunn, one of several officers in the hearing room who defended the Capitol, was seen wiping away tears before Chairman Bennie Thompson called a short recess.

Some members of Congress watching in the public seats teared up, clearly rocked with emotion by the horrific memory.

Rep. Pramila Jayapal, D-Wash., held tissues in her hands. Around the hearing room, people shook their heads yet intently watched the footage.

Rep. Liz Cheney, R-Wyo., said for the first time publicly that multiple Republican members of Congress reached out to the Trump White House to ask for presidential pardons in the wake of the Jan. 6 attack, including Rep. Scott Perry, R-Pa.

"Multiple other Republican congressmen also sought presidential pardons for their roles in attempting to overturn the 2020 election," she added.

As with other House Republicans, Perry has refused to cooperate with the committee's investigation through voluntary requests and a congressional subpoena.
