The former general counsel of the U.S. Department of Homeland Security on Thursday joined the defense team of accused leaker Reality Winner.

Joe D. Whitley, a partner at Atlanta’s Baker Donelson, filed a motion for permission to appear on Winner’s behalf. Whitley has a long history of government service. President Ronald Reagan named Whitley as U.S. attorney for Middle District of Georgia in Macon, and President George H.W. Bush appointed him to serve as U.S. attorney for the Northern District of Georgia in Atlanta.
