The Pentagon said Lt. Gen. Brett Sylvia failed three polygraph examinations after Defense Secretary Pete Hegseth fired him from the Joint Staff this week, a rare public disclosure that turned an internal leak probe into a privacy-law dispute.
The timing matters because the disclosure landed the same day readers were already searching for the reason behind the ouster. Sylvia had been serving as the director of strategy, plans and policy for the Joint Staff, known as the J5, and had built a reputation as a highly decorated three-star general with a Purple Heart and six Bronze Star Medals, including one for valor.
On October 30, 2026, a Pentagon official said the failed tests were tied to allegations that Sylvia leaked classified information about Iran and the Russia-Ukraine war. Brad Moss said the Privacy Act of 1974 bars public disclosure of that kind of information from an official file without consent, and that courts have also recognized that verbal disclosures can violate the law. In that sense, the public release of a personnel detail was not a side note. It became part of the story.
There is also a sharp split inside the Pentagon’s own account. Two Pentagon sources confirmed the firing was connected to the polygraph tests, but disputed the claim that Sylvia leaked classified information. reported that Sylvia spoke to at least one journalist while on the Joint Staff but denied sharing any sensitive or classified information. Axios later reported that Sylvia admitted to leaking classified information about Ukraine and Iran to two reporters from separate news outlets over a one year period.
That leaves the central question less about the firing itself than about what the Pentagon believed it had, and why it chose to say so publicly. Polygraph results are ordinarily kept in personnel security or counterintelligence records, which is why the release immediately raised Privacy Act concerns. The investigation remained ongoing and had been referred to the Justice Department, which means the dispute over what Sylvia said, what the Pentagon knew, and what it was allowed to disclose is now moving beyond an internal personnel action.
For now, the firing is settled. The justification is not.
