Pentagon Fires Top Planner for Leaking Classified Iran, Ukraine Intel
Lt. Gen. Brett Sylvia admitted leaking classified Iran and Ukraine intelligence for over a year.
Why it matters: Leaks by senior military officials risk compromising national security and may lead to criminal prosecution, affecting legal compliance and defense operations.
- Sylvia leaked classified Iran and Ukraine information starting June 2025 via encrypted Signal messages and a meeting in Arlington, VA.
- He failed three polygraph exams related to the leaks and was dismissed by Defense Secretary Pete Hegseth in October 2026.
- The Pentagon forwarded the case to the Department of Justice for possible prosecution.
- Sylvia served 32 years, including as commander of the 101st Airborne Division until May 2025.
- He was director of strategy, plans, and policy for the Joint Chiefs of Staff before his firing.
Army Lt. Gen. Brett Sylvia, a senior Pentagon military planner, admitted to leaking classified information about Iran and Ukraine to two journalists over roughly 16 months, beginning in June 2025, according to Axios. Sylvia communicated via encrypted Signal texts and held at least one in-person meeting at a diner in Arlington, Virginia, where sensitive details were disclosed.
With 32 years of military experience, Sylvia most recently served as commander of the 101st Airborne Division at Fort Campbell, Kentucky until May 2025. He then became director of strategy, plans, and policy for the Joint Chiefs of Staff — a key advisory role overseeing military planning. Following three failed polygraph tests related to the leaks, Defense Secretary Pete Hegseth dismissed him from his post in October 2026, reports the Associated Press.
The Pentagon referred the investigation to the Department of Justice, indicating possible criminal charges. An interrogation video features Sylvia’s admissions. The Joint Staff withdrew prior commendations, acknowledging they did not reflect the full context of his conduct.
Pentagon spokesman Sean Parnell said, "Necessary personnel actions were taken to safeguard sensitive information." This incident contributes to ongoing Pentagon efforts to tighten controls around classified intel and journalist engagement under Secretary Hegseth’s tenure.
This case serves as a warning for all senior defense officials, underscoring the legal risks of unauthorized disclosures and challenging the protocols protecting sensitive military operations related to Iran and Ukraine.
By the numbers:
- 16 months — duration of Sylvia's leaking from June 2025 to October 2026
- 32 years — Sylvia's total military service length
- 3 — number of failed polygraph tests linked to the leaks
What's next: The Department of Justice is expected to determine whether to file criminal charges against Sylvia based on Pentagon referrals and investigation findings.
