In her closing statements, committee vice chair Rep. Liz Cheney, R-Wyo., acknowledged the testimony from dozens of Republican witnesses throughout its investigation.

"The case against Donald Trump in these hearings is not made by witnesses who were his political enemies," she said. "It was, instead, a series of confessions by Donald Trump's own appointees."

That included those who served Trump loyally for years and his own family members, she said.

She thanked the witnesses -- including ex-staffers Sarah Matthews, Matthew Pottinger and Cassidy Hutchinson -- for their bravery in speaking out publicly before millions of Americans.

"[Hutchinson] knew all along that she would be attacked by President Trump and by the 50-, 60- and 70-year-old men who hide themselves behind executive privilege," Cheney said.

Rep. Adam Kinzinger said one area where all Americans must agree is on Trump's behavior on Jan. 6.

"Whatever your politics, whatever you think about the outcome of the election, we as Americans must all agree on this: Donald Trump's conduct on Jan. 6 was a supreme violation of his oath of office and a complete dereliction of his duty to our nation," the Illinois Republican said.

"It is a stain on our history," Kinzinger continued. "It is a dishonor to all those who have sacrificed and died in service our democracy."

The House select committee shared never-before-seen raw footage of outtakes from former President Donald Trump's recorded message on Jan. 7, in which he "still could not say that the election was over," Rep. Elaine Luria, D-Va., said.

"This election is now over. Congress has certified the results," Trump starts to say, then adding, "I don't want to say the election is over."

"I just want to say Congress has certified the results, without saying the election is over, OK?" he continues.

Trump had refused to record the address for hours, Luria said, but ultimately relented "because of concerns that he might be removed from power by threats of the 25th Amendment."

The 25th Amendment lays out the procedures for replacing the president in the event of death, removal, resignation or incapacitation.

Rep. Elaine Luria, D-Va., introduced what she called "never-before-seen" photos and videos of what lawmakers were doing during the attack.

Congressional leaders called then-acting Secretary of Defense Chris Miller at 4:45 p.m. that day to regain control of the Capitol.

"We're not going to let these people keep us from finishing our business," GOP Sen. Mitch McConnell can be heard saying in a huddle of lawmakers. "So, we need you to get the building cleared, give us the okay so that we can go back in session and finish the peoples' business as soon as possible."

Sen. Chuck Schumer, D-N.Y., then asked Miller if he agreed with one assessment that it was going to take "several days" to secure the area. Miller disagreed, stating it would take four to five hours.

At one point, Schumer, House Speaker Nancy Pelosi and House Majority Steny Hoyer grouped together taking a phone call about securing the Capitol.
