BEDFORD, MASS. (WHDH) - Jack Teixeira, the Massachusetts airman who pleaded guilty to charges in connection with a top secret leak of classified military documents, appeared at Hanscom Air Force Base Tuesday to face charges that could lead to a court-martial.

While his federal case moves toward sentencing, Teixeira has also been charged in the military justice system with one count of failure to obey an order and two counts of obstruction of justice.

His hearing on Tuesday was similar to a preliminary hearing for civilians and will determine whether there is enough evidence to begin a special court-martial.

Teixeira was present in military uniform surrounded by three members of his defense. His family was also in the room.

The 22-year-old from North Dighton remained stoic and only spoke when addressed by the preliminary hearing officer, who conducted the hearing virtually from D.C.

The morning started with the government laying out their evidence as to why the case should go before a court-martial.

That evidence includes transcripts, pictures and memorandums from military personnel.

A sticking point during the hearing was whether the government could present documents from Discord – the social media site Teixeira is accused of leaking that information.

But the judge ultimately decided not to consider that evidence.

Teixeira was arrested in April of last year after authorities said he shared highly-classified documents about the war in Ukraine and other national security matters on Discord. 

Teixeira pleaded guilty to federal charges in the case in March and is set to be sentenced as part of his plea deal in September. 

Teixeira is still considered an airman first class active duty pending the outcome of his potential court-martial.

If he’s found guilty of the new military justice charges, he could also face additional prison time.

The decision could be a few months away, according to an Air Force spokesperson from Washington, D.C.
