War Secretary Pete Hegseth fired one of the Pentagon’s senior strategic planners amid an investigation into allegations he leaked classified information to journalists about the Iran war, Russia’s war in Ukraine and other sensitive matters, a Department of War official told Fox News.
The official said Lt. Gen. Brett Sylvia failed three polygraph examinations related to alleged disclosures of classified information. The investigation has been referred to the Justice Department.
Sylvia is also accused of meeting journalists outside the Pentagon with the alleged intention of leaking classified material after Hegseth imposed new media restrictions requiring reporters to be escorted inside the building.

Fox News Digital has reached out to the DOJ and Sylvia for comment but did not hear back at time of publication.
Sylvia served as director of the Joint Staff’s Directorate for Strategy, Plans and Policy, known as the J5, a senior role responsible for developing military strategy and advising the chairman of the Joint Chiefs. The J5 has been sidelined from that role since the spring, according to well-placed sources who spoke to Fox News.
The official stressed that Sylvia was not a central planner of the Iran war, which falls under U.S. Central Command and its commander, Adm. Brad Cooper.
The Atlantic first reported Sylvia’s ouster Wednesday night, citing sources who said Hegseth had lost confidence in the three-star general amid tensions with Pentagon policy chief Elbridge Colby.

Sylvia is the second officer leading the J5 to be removed under Hegseth, following Lt. Gen. John McGee. Hegseth also removed Lt. Gen. Douglas Sims, then director of the Joint Staff, earlier this year.
The abrupt removal comes as the Pentagon reportedly weighs renewed military action against Iran.
U.S. officials have reportedly warned allies in the Middle East to prepare for possible renewed strikes after next week’s midterm elections and potential Iranian retaliation, while additional U.S. forces are moving into the region.

A 1994 West Point graduate, Sylvia has served more than three decades in the Army, including multiple deployments to Iraq and Afghanistan, and was wounded in combat. Before taking over the J5 in December, he commanded the 101st Airborne Division at Fort Campbell and had previously served as the J5’s vice director.

Sylvia’s removal is the latest in a broader turnover of senior military leadership under Hegseth, with nearly two dozen generals, admirals and other senior leaders fired, pushed out or otherwise departing during his tenure.
