In reversal, Mulvaney says he won't sue over impeachment probe subpoena

White House acting chief of Staff Mick Mulvaney on Tuesday said in a court filing that he would not bring a lawsuit challenging a subpoena for his testimony in the impeachment probe into President Donald Trump, adding that at the direction of the president he would not cooperate with the investigation.

The move was a reversal for Mulvaney, who on Monday said in a court filing that he planned to bring a lawsuit.
