President Biden is instructing the Department of Defense to limit the distribution of sensitive information.
This comes after the alleged leaking of classified documents on the Internet by Massachusetts National Guard member Jack Teixeira, who was arrested last week at his home in Dighton.
According to a criminal complaint, Teixeira had a top-secret security clearance made possible through his job as a "cyber transport systems journeyman" at Joint Base Cape Cod.
The 21-year-old remains in federal custody pending a court hearing on Wednesday.
