A former top advisor to War Secretary Pete Hegseth, who was ousted amid a high-profile leak investigation, has been hired to work under Director of National Intelligence Tulsi Gabbard, according to a source familiar with the move.
Dan Caldwell’s return to a sensitive intelligence role comes less than a year after he was publicly accused of leaking classified information — allegations that have never been publicly substantiated — and as the Trump administration navigates an escalating war with Iran.
The hiring also places a prominent advocate of a more restrained U.S. foreign policy inside the intelligence apparatus at a moment of growing internal tension.

Earlier Tuesday, National Counterterrorism Center Director Joe Kent resigned, citing opposition to the Iran war and arguing Tehran, Iran, did not pose an imminent threat to the United States — a rare public break from within the administration.
A source familiar with the move described Caldwell’s new position as an “administrative role,” focused on internal management and coordination rather than directly shaping intelligence assessments or national security policy. However, the Office of the Director of National Intelligence (ODNI) plays a central role in coordinating intelligence across 18 agencies and shaping the president’s daily intelligence briefing.

The source said Caldwell has completed a polygraph test, and passed a series of background and security checks and is currently in the onboarding process.
Gabbard’s office could not immediately be reached for comment.
A recent Quinnipiac poll found the war is dividing Americans just as it is those within the administration: 53% of those surveyed opposed the military intervention while 40% supported it.
Caldwell’s hiring signals the apparent end of a leak investigation that began in April 2025, when Caldwell and two other senior Pentagon officials, Darin Selnick and Colin Carroll, were abruptly fired and escorted out of the Pentagon. All three aides have denied any involvement in leaks, and no public evidence has been produced to support the allegations.
Hegseth said at the time the three aides would be investigated for leaking and suggested there was evidence of wrongdoing, but none of the men were ever charged, and Caldwell retains his security clearance.
The Pentagon has not disclosed whether the investigation remains active or has concluded.

Fox News Digital previously reported that the three aides had clashed with then-chief of staff Joe Kasper, who was also later removed from his role.
Hegseth continued to accuse the aides of leaking even after their departure, saying at the time: “Those folks who are leaking, who have been pushed out of the building, are now attempting to leak and sabotage the president’s agenda and what we’re doing. And that’s unfortunate.”
Caldwell, a Marine Corps veteran and prominent voice in the restraint-minded foreign policy sphere, advised Hegseth primarily on European issues and has been outspoken against prolonged U.S. military involvement overseas. His views align with a faction inside the administration that has long warned against entering another major Middle East conflict.

That debate has taken on new urgency as the U.S. enters its third week of war with Iran, and as Gabbard — who built much of her political identity opposing regime-change wars — has remained largely quiet publicly about the conflict despite overseeing the nation’s intelligence apparatus.
After his firing, Caldwell suggested the trio’s removal may have been tied to internal power struggles. “We threatened a lot of established interests inside the building and outside the building,” he said.
