The US Department of Justice has taken into custody a Massachusetts Air National Guard member, Jack Teixeira, who is believed to be the leader of a Discord chat group where highly classified military documents on the Ukraine war were posted. Attorney General Merrick Garland has charged Teixeira with the unauthorized removal of classified national defense information, and the FBI has taken him into custody. The US Department of Justice is continuing to investigate the incident and is urging anyone with information to contact the FBI.
