Gen. Brett Sylvia, the Pentagon's former top military planner, is under federal investigation and may face military charges for leaking classified information about Ukraine and Iran to reporters from the Wall Street Journal and the New York Times. Sylvia, who was fired last week by Defense Secretary Pete Hegst, failed four polygraph tests and admitted to unauthorized disclosure of information in taped interviews. The Ministry of Justice is investigating the claims that he leaked details about US aid to Ukraine, ammunition stockpiles and talks with Iran.
