Jack Teixeira appeared in a courtroom of a federal court in Boston mid-morning. The IT specialist at an Air National Guard base is being prosecuted for leaking classified army documents to friends in a discussion group on a video game forum.

The indictment states that he also used his clearance to conduct research on the word leak in early April, presumably to try to find out if the investigation was getting closer to him. He remains in custody pending a hearing scheduled for next Wednesday. The Justice Department will ask that he remain imprisoned until trial.
