The presiding judge overseeing the prosecution of a U.S. Air Force veteran accused of leaking information about Russian hacks of state election systems has issued an order threatening lawyers with contempt if they talk publicly about the case.

Randal Hall, chief judge of the U.S. District Court for the Southern District of Georgia in Augusta, issued the order June 7 on his own motion. In it, he warned “all present and prospective attorneys” that no violations will be tolerated of a local rule largely barring attorneys’ public comment in ongoing criminal cases. Violation of the rule, Hall wrote, “may result in contempt proceedings or other measures.”
