Kent said on social media that Iran “posed no imminent threat to our nation, and it is clear that we started this war due to pressure from Israel and its powerful American lobby.”

Kent, a former political candidate with connections to right-wing extremists, was confirmed to his post last July on a 52-44 vote. As head of the National Counterterrorism Center, he was in charge of an agency tasked with analyzing and detecting terrorist threats. His resignation reflects unease within Trump’s base about the war and shows that questions about the justification for the use of force in Iran extend to the right of President Donald Trump’s base and to senior members of the administration.

Trump has offered shifting reasons for the strikes and has pushed back on claims that Israel forced the U.S. to act. Earlier this month, House Speaker Mike Johnson, R-La., suggested that the White House believed Israel was determined to act on its own, leaving the Republican president with a “very difficult decision.”

A spokesperson for Director of National Intelligence Tulsi Gabbard did not immediately respond to questions about Kent’s resignation. The White House also had no immediate comment on Kent’s resignation.

Before entering Trump’s administration, Kent ran two unsuccessful campaigns for Congress in Washington state. He also served in the military, seeing 11 deployments as a Green Beret, followed by work at the CIA.

Democrats strongly opposed Kent’s confirmation, pointing to his past ties to far-right figures and conspiracy theories. During his 2022 congressional campaign, Kent paid Graham Jorgensen, a member of the far-right military group the Proud Boys, for consulting work. He also worked closely with Joey Gibson, the founder of the Christian nationalist group Patriot Prayer, and attracted support from a variety of far-right figures.

During his Senate confirmation hearing, Kent also refused to distance himself from a conspiracy theory that federal agents instigated the Jan. 6, 2021, attack at the Capitol, as well as false claims that Trump won the 2020 election over Democrat Joe Biden.

Democrats grilled Kent on his participation in a group chat on Signal that was used by Trump’s national security team to discuss sensitive military plans.

Still, Republicans praised Kent’s counterterrorism qualifications, pointing to his military and intelligence experience.

Sen. Tom Cotton, the GOP chair of the intelligence committee, said in a floor speech that Kent had “dedicated his career to fighting terrorism and keeping Americans safe.”
