Rep. Liz Cheney says Jan. 6 committee has conducted more than 150 interviews

WASHINGTON – The House select committee investigating the events leading up to, and surrounding, the insurrection attempt on the U.S. Capitol is making significant behind-the-scenes progress, according to its members.

Rep. Liz Cheney, R-Wyo., co-chair of the committee, told reporters the committee has conducted more than 150 interviews so far, according to an aide. 

"That just gives you a sense. It is a range of engagements — some formal interviews, some depositions," said Cheney to Politico, which first reported the story. "There really is a huge amount of work underway that is leading to real progress for us.” 

The chair of the committee, Rep. Bennie Thompson, D-Miss., has signed 20 additional subpoenas that could be issued imminently, according to a select committee aide.

The committee has made very few moves in the public eye. The committee has only held one public hearing, where they heard harrowing accounts from police offers who were beaten by protesters that day, who had been spurred by former President Donald Trump's false claims of a stolen election.

In mid-October, the committee voted unanimously to hold former Trump adviser Steve Bannon in contempt after he refused to cooperate with the panel's subpoena.

Soon after, the House of Representatives voted to hold him contempt, sending the contempt report to the Justice Department, which has final say on whether to prosecute Bannon.

The committee has subpoenaed well-known people in Trump's world, including former White House chief of staff Mark Meadows, former deputy chief of staff Dan Scavino and former Trump adviser Kash Patel.

The committee is also attempting to hear from lesser-known characters in the Jan. 6 events, like Amy and Kylie Jane Kremer, the mother-daughter duo who formed a viral Facebook group urging "boots on the ground" on Jan. 6 to disrupt the counting of electoral votes.
