Secretary of War Pete Hegseth has abruptly fired one of the Pentagon's top military strategists, curiously at a sensitive moment which has seen the Trump administration draw up options for a renewed, intensified Iran war - likely to come after the midterm elections.

Army Lt. Gen. Brett Sylvia has been dismissed from his post as director for strategy, plans, and policy (J5) on the Joint Staff, a Pentagon spokesperson confirmed late Wednesday.

This marks the second turnover in that key position within about a year, after Sylvia's predecessor, Lt. Gen. Joseph McGee, was initially removed.

Since Trump took the White House, Hegseth has pushed some two dozen senior military and civilian officials out of top command positions.

But what makes Gen. Sylvia's firing more notable and alarming is that Hegseth's office is citing "severe misconduct". He's stands accused of leaking classified info related to the Iran and Ukraine conflicts. However, the Pentagon has yet to state this publicly, or to offer an official explanation.

CBS reports, "The official, who spoke on condition of anonymity to discuss sensitive personnel matters, said Army Lt. Gen. Brett Sylvia was accused of misconduct for leaking classified information related to the Iran war and the Russia-Ukraine war."

"Sylvia failed three polygraph tests about sharing classified information with the press, the official said, adding that the case has been referred to the Department of Justice," the report continues.

According to a fuller statement on the allegations from an unnamed US defense official:

"Army Lieutenant General Brett Sylvia, who was part of the Joint Chiefs of Staff, was fired by Secretary Hegseth for severe misconduct. Although Sylvia's title was director of the Directorate for Strategy, Plans, and Policy at the Joint Chiefs of Staff, known inside the military as the J5, he was NOT a central planner for the Iran War. That is the responsibility of CENTCOM and its commander Admiral Cooper. 

Sylvia is the subject of an investigation for leaking classified information about the Iran War, the war between Russia and Ukraine, and more. Due to the Pentagon's media policy requiring journalists to have escorts in the building, Sylvia began meeting with journalists outside of the Pentagon in order to leak classified information. Sylvia failed three polygraphs which questioned him about leaking classified information. The investigation into him remains ongoing and has been referred to the Department of Justice for further action. 

The extent of his leaking became so critical that Secretary Hegseth took immediate action and fired Sylvia in order to protect national security. Urgent action was needed and could not wait another second."
