A 21-year-old Air National Guardsman faces federal charges for leaking classified documents, and an Illinois Senior Senator is frustrated.

Democratic Whip Dick Dubin says this is not the first-time classified documents were leaked to the public.

Earlier this week, the Department of Justice charged Jack Teixeira for allegedly leaking hundreds of intelligence documents about Russian efforts in Ukraine. Federal prosecutors say Teixeira allegedly leaked the documents on Discord's gaming chat site. Teixeira was serving in the Massachusetts Air National Guard when the documents were leaked.
