Joe Kent, the former director of the National Counterterrorism Center, is under FBI investigation over questions about whether classified information was improperly disclosed, according to officials familiar with the matter. The inquiry surfaced shortly after Kent resigned from his post during a public dispute over U.S. policy toward Iran.

His resignation followed internal disagreements about the administration’s justification for military action. People briefed on the situation said Kent argued Iran did not present an imminent threat to the United States and pushed back on claims used to support the conflict.

Kent had been a visible national security figure inside the administration, and his departure quickly drew attention because it came at a tense moment in Washington. The investigation adds another layer to that debate, linking a personnel shake-up to a sensitive federal inquiry.

No public charges have been announced, and the exact scope of the investigation remains unclear. For now, the case stands as part of a larger clash over intelligence, national security decision-making, and how the administration handled one of its most contentious foreign policy crises.
