Army Secretary Driscoll Resigns After 18 Months Amid Hegseth Tensions

Dan Driscoll submitted his resignation as Army secretary Monday night after 18 months on the job, marking another shakeup inside a Defense Department already managing an active conflict with Iran. The move comes amid reports of friction with Defense Secretary Pete Hegseth and stalled efforts to reshape the service around actual combat needs rather than legacy programs.

White House spokeswoman Anna Kelly credited Driscoll with advancing readiness and lethality priorities while assisting in Russia-Ukraine talks. She described the Army as stronger under his tenure alongside the president. Driscoll, a Yale Law School classmate of Vice President JD Vance and a former Army officer who deployed to Iraq, had been tapped by President Trump as a change agent when nominated in 2024. Colleagues like Rep. Steve Womack praised his common-sense approach to discipline and mentoring.

Behind the departure lie two main tensions. Driscoll backed the Army Transformation Initiative, which aimed to merge Futures Command with Training and Doctrine Command while trimming expensive systems such as the AH-64D Apache, M10 Booker combat vehicle, and Gray Eagle drone. Those steps ran into resistance inside the building. At the same time, Hegseth had already removed Army Chief of Staff Gen. Randy George earlier this year. George had worked closely with Driscoll on those modernization plans. Officials close to the situation described an atmosphere of suspicion directed at Driscoll, partly tied to his long-standing ties to Vance.

The timing adds pressure. U.S. forces have faced Iranian missile attacks in recent days following strikes near the Strait of Hormuz. The service now lacks Senate-confirmed leadership at both the civilian and uniformed levels during an ongoing operation. Axios reported that Driscoll spoke directly with the president about his concerns before deciding to leave, despite a request to stay through the midterms.

Driscoll earned the nickname “drone guy” for focusing on lower-cost, high-volume capabilities suited to modern fights. That approach clashed with entrenched interests that favor big-ticket platforms and sustained foreign commitments. Sources described the overall atmosphere as one of internal chaos rather than steady reform.

Driscoll’s exit follows a pattern of turnover that leaves the largest service in flux. His background as a combat veteran and outsider gave him leverage to question old assumptions about equipment and structure. The administration’s stated goal of restoring lethality now faces another test as new leadership must be confirmed and integrated while operations continue abroad.
