Peter Navarro, a top former White House adviser to Donald Trump, was indicted by a federal grand jury on Friday on two counts of contempt of Congress after he defied a subpoena issued by the House select committee investigating the January 6 Capitol attack.

The justice department said in a news release that Navarro was indicted with one count for refusing to appear at a deposition and another for refusing to turn over documents as required by the panel's subpoena.
