SCOOP: Top Hegseth aide resigns from Pentagon after 6 months of service: 'Incredibly inspiring'

Justin Fulcher told Fox News Digital he formally resigned on Thursday evening, describing the decision as entirely his own.

Fulcher said he had originally planned to serve six months in government and, having reached that point, chose to move on "amicably." He also emphasized what he described as the "great work" being done by Hegseth "for our troops and country."

In addition to advising Hegseth on personnel and policy, Fulcher played a role in several defense initiatives during his tenure, he told Fox News Digital.

Fulcher said he contributed to reviews of major acquisition programs aimed at strengthening lethality and the U.S. industrial base, and helped streamline software procurement timelines "from years to months," modernizing key IT systems across the department.

He also said he supported Hegseth in high-level meetings across the Indo-Pacific, including the Shangri-La Dialogue in Singapore, and participated in efforts that redirected nearly $50 billion from non-lethal line items into readiness and more impactful defense programs.

"As planned, I've completed 6 months of service in government to my country," he wrote, calling the experience "incredibly inspiring."

"None of this could have happened without Secretary Hegseth's decisive leadership or President Trump's continued confidence in our team," he wrote. "I will continue to champion American warfighters in all future endeavors."

Fulcher joined the DoD earlier this year as part of Hegseth's inner circle, a cohort of loyal advisers appointed after Hegseth took the helm at the Pentagon in Trump's second term.

His departure comes amid a broader reshuffling of senior personnel inside Hegseth's office. At least six aides have left since January, though defense officials have downplayed the moves as standard transitions.

It's unclear what Fulcher's next step will be, though his statement suggests he intends to remain active in national security circles.

The Pentagon has not yet named a replacement.
