The Intelligence Community whistleblower complaint at the center of a controversy centered on whether President Trump improperly pressured Ukraine’s leader to investigate a political rival has been released.

Its disclosure by the House Intelligence Committee on Thursday morning sets the stage for a rare open hearing in which members of the House Intelligence Committee will ask questions of acting Director of National Intelligence Joseph Maguire, the official who under guidance from the Justice Department and the White House blocked the complaint’s release up until now.
