Mick Mulvaney on Tuesday said he would defy a U.S. congressional subpoena seeking his testimony as part of the impeachment inquiry, abruptly dropping plans to file a lawsuit to confront whether House Democrats could force him to sit for questioning.

The about-face came a day after Mulvaney’s lawyer, William Pittard of Washington’s KaiserDillon, told a Washington federal trial judge that the acting White House chief of staff would file his own suit confronting the power of House Democrats to compel top Trump officials to testify.
