The FBI is investigating former National Counterterrorism Center Director Joe Kent over allegations that he leaked classified information, with the probe reportedly beginning before his resignation.

Kent stepped down Tuesday, citing opposition to the U.S. war against Iran, which he argued was unnecessary and violated the administration’s prior non-interventionist approach.

A senior official described Kent as a “known leaker” who had been excluded from intelligence briefings months before leaving his post.

It is unclear whether the FBI investigation relates to those prior concerns or a separate matter, Fox News has reported.

Kent, a former Army Green Beret and CIA paramilitary officer, was appointed NCTC director in early 2025 and is also a Gold Star spouse.
