WASHINGTON - White House acting Chief of Staff Mick Mulvaney plans to file his own lawsuit over the House impeachment inquiry rather than join an existing one brought by one of the president's former advisers.

That's according to a court filing Monday evening withdrawing Mulvaney's earlier motion to join a lawsuit from Charles Kupperman. The motion followed a private telephone conference call with a judge.

Kupperman, the former deputy national security adviser to President Donald Trump, asked a judge to decide whether he had to comply with a subpoena from the House or an order from the White House directing him to not testify.

Lawyers for Kupperman and House Democrats opposed Mulvaney's effort to join the suit, saying his case presented some different issues.
