The Pentagon's former chief strategist admitted to leaking classified information about Ukraine and Iran to journalists, according to Axios. Lt. Gen. Brett Sylvia, former head of the Joint Chiefs of Staff's Strategic Planning Directorate, was fired this week. According to the publication, Sylvia pleaded guilty after failing four polygraph tests. The leaks started as early as June 2025. He used the secure messaging app Signal to pass classified information to journalists, and met with one of the press representatives in person.
