Attorneys for Steve Bannon are asking a judge to throw out his contempt of Congress guilty verdict because of the judge’s pretrial decision to prevent Bannon from calling members of Congress as witnesses.

The decision by District Judge Carl Nichols of the District of Columbia to quash Bannon’s subpoena to House Jan. 6 select committee chair Rep. Bennie Thompson and other committee members denied Bannon his “right to due process of law, his right to compulsory process, his right of confrontation, his right to effective assistance of counsel and to a fair jury trial,” his attorneys wrote in a court filing Friday.
