Jack Teixeira, the Massachusetts Air National Guardsman convicted of federal offenses for leaking sensitive information online, pleaded guilty Thursday to a military charge of obstructing justice, a spokesperson for his family confirmed.

A military court-martial convened this week at Hanscom Air Force Base in Massachusetts on charges alleging Teixeira violated the Uniform Code of Military Justice.

Teixeira pleaded guilty to the obstruction charge at the court-martial on Thursday, his family spokesperson confirmed. A second charge of disobeying orders was dropped as part of a plea agreement, which calls for dishonorable discharge and no confinement, according to the spokesperson.

He is expected to be sentenced later Thursday, according to the spokesperson.
