Liz Cheney said that Donald Trump's storing of highly classified documents at his Mar-a-Lago estate shows how destructive he has been to the GOP.
Cheney called out senior members of the GOP who are going through contortions to support Trump, such as those who slammed federal agents who executed a search warrant at his Florida residence on August 8.
"I think it's the latest example of how fundamentally destructive Donald Trump has been and part of the destruction that he's caused is the behavior that my party apparently now will accept," she said.
One of the few GOP critics of Trump has been the vice chair. She gave her congressional seat to a Trump supporter.
During the interview, Cheney said that there will be new information during the meeting in Washington, DC.
Cheney said she is hopeful that former Vice President Mike Pence will testify.
She said that the vice president played a key role in the events of January 6, when he refused to reverse the result of the election.
In one of her first speeches since her primary defeat, Cheney said that Pence was the president for most of the day.
