7 sources →

Secretary of War Pete Hegseth has removed Army Lt. Gen. Brett Sylvia from his role as the Pentagon's director for strategy, plans, and policy. The dismissal occurs amid a reported investigation into allegations that Sylvia leaked classified information regarding military operations in Iran and the Russia-Ukraine conflict. While some outlets report the removal was due to Sylvia failing three polygraph tests and meeting with journalists outside the Pentagon, others note that no official reason was publicly provided at the time of the announcement. This departure follows a broader pledge by the Trump administration to reduce the number of high-ranking military officials.
