WASHINGTON (AP) — White House acting chief of staff Mick Mulvaney says he won’t sue over the House impeachment proceedings after all. It’s the latest reversal in position by Mulvaney, who last week asked to join an existing lawsuit before saying Monday that he intended to bring his own case. In a court filing Tuesday, Mulvaney says he’ll rely on the direction of President Donald Trump and won’t cooperate with the impeachment proceedings.
