Former White House Chief of Staff Mark Meadows filed a lawsuit against House Speaker Nancy Pelosi and members of the lower chamber’s Select Committee on Jan. 6 Wednesday.

Meadows, who initially cooperated with the committee before pulling back, faces imminent contempt charges after the former President Trump chief failed to show for a scheduled deposition.

“The select committee is left with no choice but to advance contempt proceedings and recommend that the body in which Mr. Meadows once served refer him to criminal prosecution,” wrote Select Committee Chairman Bennie Thompson, D-Miss., in a letter to Meadows’ attorney, according to The New York Times.
