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.
Fulcher praised the "dedicated men and women of the Department of Defense," cited progress in "revitalizing the warrior ethos" and "rebuilding the military," and thanked both Hegseth and Trump for their leadership. "Still, this is just the beginning," Fulcher added.
Fulcher, who had served as a senior advisor to Hegseth since April, announced his departure Saturday afternoon in a message posted to X.
"As planned, I’ve completed 6 months of service in government to my country," he wrote, calling the experience "incredibly inspiring."

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.
