A hearing to determine whether a 21-year-old Massachusetts Air National Guardsman accused of leaking sensitive government documents has been rescheduled for next week in a Worcester federal courtroom.

The hearing for Jack Teixeira was originally scheduled for Thursday but it was canceled the day before without a public explanation, though it is common for court dates to move around. Teixeira is now scheduled to appear before Magistrate Judge David Hennessy at 2:30 p.m. on Tuesday, according to new court records updated Friday afternoon.

Lawyers for the federal government accuse Teixeira, a low-ranking service member who was based out of Joint Base Cape Cod, of using his top-secret security clearance to illegally leak documents on Discord, a social media platform designed for video game enthusiasts.

Prosecutors charged him with unauthorized retention and transmission of national defense information and unauthorized removal and retention of classified documents or material in connection to one document on the war in Ukraine leaked in February 2023.

And prosecutors argue Teixeira poses a “serious” flight risk because the evidence against him is “substantial and mounting.” The 21-year-old, prosecutors said, could have more classified information “that would be of tremendous value to hostile nation states that could offer him safe harbor and attempt to facilitate his escape from the United States.”

Teixeira’s defense attorneys have said the idea that other countries could provide him safe harbor is “little more than speculation that a foreign adversary will seduce Mr. Teixeira and orchestrate his clandestine escape from the United States.”
