WASHINGTON The House committee investigating Donald Trump s attempted coup to remain in power wrapped up its summer series of public hearings Thursday night, going through a minute-by-minute account of his refusal to tell the violent mob he had called to the U.S. Capitol to stand down.

Donald Trumps conduct on Jan. 6 was a supreme violation of his oath of office and a complete dereliction of his duty, said Rep. Adam Kinzinger, an Illinois Republican. It is a stain on our history.

Kinzinger pointed out that Trump did not send out his eventual message telling his followers to go home until 4:17 p.m. EST that day, when it was clear that his effort to pressure Vice President Mike Pence and lawmakers to simply declare him the winner of the 2020 presidential had failed and that law enforcement officers were regaining control of the building.

Liz Cheney, a Wyoming Republican and the committees vice chair, went back through evidence from the previous seven hearings, including Trumps claims that millions of illegal votes were counted, that voting machines were somehow controlled by a foreign power and that election workers had manipulated the totals with data off of flash drives.

All complete nonsense, she said. We cannot abandon the truth and remain a free nation.

The committee members, absent chair Bennie Thompson (D-Miss.), who attended the meeting remotely after coming down with COVID-19, filed into the room and face witnesses Sarah Matthews and Matt Pottinger, two former Trump White House aides who were both in the White House on Jan. 6, 2021.

Cheney presided over the hearing, gaveling it into session at 8:01 p.m. Eastern time in the soaring-ceilinged Cannon Caucus Room, packed with extra rows of seats to accommodate the heightened interest.

She immediately announced that because of the new information the committee has been receiving and progress with litigation, the panel would resume hearings in September. The dam has begun to break, Cheney said.

The committee began with confirmation of some of the most dramatic testimony by former top White House aide Cassidy Hutchinson about an irate Trump in the presidential SUV demanding that his Secret Service detail take him to the Capitol so he could lead his followers.
