Bannon has refused to cooperate with the House of Representatives select committee seeking testimony and documents from him, citing Trump's insistence — already rejected by one judge — that he has a right to keep the requested material confidential under a legal doctrine called executive privilege.
Bannon, 67, was charged with one count of contempt of Congress for refusing to appear for a deposition and a second count for refusing to produce documents. Contempt of Congress is a misdemeanour punishable by up to one year in jail and a maximum fine of $100,000.
Justice Department spokesperson Bill Miller said Bannon is "expected to self-surrender" on Monday in Washington and make his first court appearance in the case that afternoon.
