WASHINGTON (AP) — Massachusetts Air National Guard member Jack Teixeira, who pleaded guilty to federal criminal charges for leaking highly classified military documents about the war in Ukraine and other national security secrets, will face a military justice proceeding later this month, officials said Wednesday.

Teixeira, of North Dighton, Massachusetts, faces two charges in the military justice system, including obstructing justice and failing to obey a lawful order, Air Force officials said. Prosecutors will present evidence during the military proceeding on May 14 at Hanscom Air Force Base in Massachusetts. The case could then move to a court-martial, if it’s determined that there’s sufficient evidence of the charges.

The military proceeding comes nearly two months after Teixeira pleaded guilty in federal court to six counts of willful retention and transmission of national defense information under the Espionage Act. That was close to a year after he was arrested in the most consequential national security leak in years.
