In a monumental development for former President Donald Trump‘s Georgia election interference indictment, a judge ruled Fulton County District Attorney Fani Willis can remain on the case, teeing up a new chapter as prosecutors and defense attorneys prepare their next moves.

Superior Court Judge Scott McAfee wrote in his order Friday that either Willis and her office or her appointed special prosecutor, Nathan Wade, would have to leave the case after finding that a previously undisclosed romantic relationship with Wade resulted in an “appearance of impropriety.”
