According to Rep. Lofgren, the House January 6 committee expects former White House strategist Steve Bannon to testify.
According to Lofgren, the committee has not had a chance to discuss the letter yet, but there are many questions they have for him.
Bannon is willing to testify at a public hearing if Trump waives executive privilege, according to the letter.
According to Forbes, Trump wrote in an earlier letter to Bannon that he would be willing to waive executive privilege, a legal doctrine which allows presidents to keep some internal communications secret.
Lofgren said that the deposition would likely be behind closed doors.
He was subpoenaed by the committee in September over his alleged connection to the Capitol riot by backing Trump's false claims of voter fraud and meeting with other Trump allies in the week leading up to the attack. Trump invoked executive privilege even though he wasn't a member of the administration when he refused to testify. In October, the House of Representatives voted to hold Bannon in contempt, and in November he was indicted on two counts of contempt of Congress. A not guilty plea has been entered by Bannon.
The trial is scheduled to start on July 18 but another attorney for Bannon, David Schoen, wants the trial to be delayed until January 6. It is not clear if his trial will continue if he testifies.
The committee subpoenaed Pat Cipollone at the end of June and he sat for an hours-long deposition on Friday. Lofgren said on CNN that the committee will play excerpts of his testimony during hearings this week and that he provided information on Trump's "dereliction of duty"
The judge rejected the motion to toss the contempt charges.
Not Guilty To Contempt of Congress, Says Bannon.
Steve Bannon was indicted for contempt of congress after he refused to comply with the subpoena.
Pat Cipollone agreed to testify before the committee after the subpoena.
