Lawyers defending accused media leaker Reality Winner are appealing a magistrate judge’s decision to bar them from issuing 40 subpoenas to federal agencies and states targeted by Russian hackers.

Winner’s defense team, led by the former general counsel of the U.S. Department of Homeland Security, has petitioned the chief judge of the Southern District of Georgia to reverse an April 28 decision by U.S. Magistrate Judge Brian Epps to halt the subpoenas’ issuance.
