The top federal prosecutor for the Northern District of Georgia abruptly resigned on Monday.

U.S. Attorney Byung “BJay” Pak previously signaled that he would stay in his position until Jan. 20, Inauguration Day, but that changed after a recording made public on Sunday revealed President Trump complaining of a “never-Trumper U.S. attorney there” during a phone conversation with Georgia Secretary of State Brad Raffensperger.
