Security concerns raised over accused Pentagon leaker's violent rhetoric and arsenal of weapons.

The case of Jack Teixeira, the 21-year-old Air National Guardsman accused of leaking classified documents online, has raised questions about the Pentagon's vetting process for security clearances. Despite red flags, including a history of violent online rhetoric and a suspension from high school over weapons-related comments, Teixeira was granted a top-secret clearance in 2021. The incident has prompted calls for a re-examination of the vetting process and a focus on preventing extremists from joining the military. The Senate Intelligence Committee is investigating the matter, and lawmakers are working on legislation to reform the classification process.
