The ex-White House lawyer's input was described by the House as "reinforcing" alleged wrongdoing by the former president.

The idea that the former White House counsel Pat Cipollone might have confirmed others witnesses' damning accounts in his much-awaited private interview Friday was initially mitigated by the possibility that he may have invoked executive privilege, a legal concept meant to allow presidents to speak freely with legal advisers.

A spokesman for the committee suggested a different story after it was reported that Cipollone invoked the privilege.

"In our interview with Mr. Cipollone, the Committee received critical testimony on nearly every major topic in its investigation, reinforcing key points regarding Donald Trump's misconduct and providing highly relevant new information that will play a central role in its upcoming hearings."

This includes information about Donald Trump's failure to fulfill his duty.

Late Saturday, Trump and his representatives didn't reply to a request for comment.

Mulvey didn't deny or confirm the reports on privilege, but he did say that Cipollone was never told to avoid potentially privileged information.

In Cipollone, the committee got another voice to back up some of the testimony of Cassidy Hutchinson, an assistant to MarkMeadows.

She testified that on January 6, 2021, Trump was filled with rage and ordered his Secret Service detail to take him to the Capitol so he could join his supporters who would eventually enter the complex and attack police.

The president lunged for the steering wheel from behind the front seats and tried to grab the throat of an agent, but he denied it.

She testified that Trump didn't show any sympathy for the vice president as the rioters were getting close to him and that he had the power to call them off. This has been denied by the former president.

According to Mulvey, Cipollone "corroborated key elements of Cassidy Hutchinson's testimony."

There will be a hearing on Tuesday.
