Pentagon leaker Jack Teixeira to be sentenced for violating Espionage Act

Former Massachusetts Air National Guardsman Jack Teixeira, who admitted he illegally posted sensitive military information to online chat rooms in what prosecutors called one of the "most prolific" and "rare" government leak operations, is set to be sentenced in a Boston courtroom on Tuesday. 

Teixeira, a 22-year-old Massachusetts native, pleaded guilty in March to six counts of violating the Espionage Act, acknowledging he was behind the yearlong distribution of dozens of classified government documents — including some marked "top secret" — on Discord, a social media platform. The classified documents involved in the leak touched on a number of sensitive issues, but the most notable were about Russia's war in Ukraine, detailed troop movements and timelines for Western weapons deliveries to the war-torn country, investigators said. 

Federal law enforcement arrested Teixeira at his family's Massachusetts home after a weekslong probe into how sensitive Pentagon records were ending up online.
