Justin Fulcher, a senior advisor to Defense Secretary Pete Hegseth, resigned from the Pentagon after six months of service, as confirmed by the Department of Defense to Fox News Digital on July 20, 2025. Fulcher described his departure as amicable and planned, stating he had intended to serve for six months. He praised Hegseth’s leadership and the progress made in revitalizing the military’s “warrior ethos,” contributing to initiatives like streamlining software procurement and redirecting $50 billion toward readiness programs. His exit is part of a broader personnel reshuffling in Hegseth’s office, with at least six aides leaving since January, though defense officials have framed these as standard transitions.
