White House national security aide declines Democrats' invitation to testify in impeachment proceeding

A top White House national security aide will not testify to Congress in the House Democrats’ impeachment investigation of President Trump’s dealings with Ukraine.

Robert Blair, a national security staffer and ally of acting White House chief of staff Mick Mulvaney, declined a Democrat invitation to give testimony in the House “pursuant to direction from the White House, which is based on advice from the Department of Justice,” Blair’s attorney, Whit Ellerman, told Politico. Blair was scheduled to testify on Monday.
