The scheduled federal detention hearing for the Massachusetts man charged with leaking military secrets to friends on a gaming-dominated social media platform has been postponed.

Jack Teixeira, 21, an E-3/Airman First Class stationed at Otis Air National Guard Base on Cape Cod, was arrested in North Dighton last week and charged in Boston federal court with unauthorized removal and transmission of national defense information and unauthorized removal and retention of classified documents or materials.

He pleaded not guilty to the charges and is being held without bail pending his full detention hearing, which was continued from Wednesday to an unspecified future date.

Teixeira is the leader of a Discord server, which is what the gaming-dominated social media platform calls individual groups or forums, with about 50 members. The feds allege that in this group he posted more than 40 images of classified documents. The images were said to have been posted to the group between December 2022 and last month.

In federal court in Boston on Wednesday, Teixeira appeared only to waive his preliminary hearing and to attest that he was doing so intelligently and that he understood what he was doing. He is represented by attorney Brendan Kelley of the Federal Public Defenders office in Boston.

The hearing was also scheduled to be a full detention hearing but that was continued at the last minute. The motion to continue and Magistrate Judge David H. Hennessy’s order granting that motion were filed in the case as many reporters were already on their way to the courtroom.

Kelley’s motion, to which prosecutors assented, asked that the hearing be scheduled two weeks later, as “the defense requires more time to address the issues presented by the government’s request for detention.”

Hennessy told counsel to confer among themselves to establish a new hearing date, which will be held in federal court in Worcester, where he normally sits.
