WASHINGTON — Army Secretary Dan Driscoll submitted his resignation to President Donald Trump on September 1, 2026. The White House announced Driscoll is stepping down after 18 months in the role.

Driscoll spoke with Trump regarding the current state of the Army before submitting his resignation. Tensions between Driscoll and Defense Secretary Pete Hegseth have been widely reported.

Hegseth fired or forced out Gen. David Hodne, Gen. James Mingus, Maj. Gen. William Green Jr. and Lt. Gen. Douglas Sims. Hegseth ousted Army Chief of Staff Gen. Randy George in April 2026.

Army Commander in Europe and Africa Gen. Christopher Donahue stepped down in June 2026. Navy Secretary John Phelan left his position in April 2026.

Gen. Christopher LaNeve serves as the Army's acting chief of staff. Under LaNeve, the Army ended a drone modernization program where a unit in Europe was building its own drones. Michael Obadal serves as the Under Secretary of the Army.

Sen. Jack Reed stated: "Secretary Driscoll worked to transform the Army for the battlefield of the future, and he engaged with Congress candidly and consistently." Reed stated: "Secretary Hegseth is cultivating a culture where dissent is punished and competence is secondary to personal allegiance."

Driscoll launched the Army Transformation Initiative in May 2025. Driscoll created the Army’s FUZE program, a venture-capital-like acquisition model. Driscoll launched the Army’s low-cost interceptor program.

Driscoll served as a key negotiator in efforts to end the war between Russia and Ukraine. Driscoll is a friend of Vice President JD Vance. Driscoll met Vance at Yale Law School.

Driscoll served as an armor officer in the U.S. Army from August 2007 to March 2011. Driscoll deployed to Iraq from October 2009 to July 2010. Driscoll ran unsuccessfully in the Republican primary for a North Carolina congressional seat in 2020, receiving approximately 8% of the vote.

Trump nominated Driscoll in 2024. The Senate confirmed Driscoll as Army Secretary in February 2025 by a vote of 66-28.

Why It Matters

The departure of Army Secretary Dan Driscoll follows a series of high-level personnel changes within the Department of Defense, including the removal of multiple general officers and the exit of the Navy Secretary. These shifts occurred alongside reports that the Pentagon hired conservative military veterans Rob Maness and Kurt Schlichter to work in the office of the undersecretary of defense for personnel and readiness. The Department of Defense published a notice on July 21, 2026, renewing the Board of Visitors, National Defense University, stating that this governance structure ensures compliance with the Goldwater-Nichols Department of Defense Reorganization Act of 1986's mandate to maintain rigorous standards for the military education of officers.

The resignation affects the continuity of Army modernization programs such as the FUZE initiative and the low-cost interceptor program. It also leaves open the question of who will succeed Driscoll as Army Secretary and how the removal of key generals will impact ongoing modernization efforts.

Timeline

In 2020, Driscoll ran unsuccessfully in the Republican primary for a North Carolina congressional seat, receiving approximately 8% of the vote. In 2024, President Donald Trump nominated Driscoll and called him "a disruptor and change agent" during his nomination.

In October 2025, Driscoll stated: "We will win with silicon and software and not our soldiers’ bodies… No one can predict the next war, but we cannot wait, we cannot fucking wait to innovate until Americans are dying on the battlefield." In November 2025, Driscoll stated: "When you look at Ukraine, [they] have not accepted the current version of a thing as sufficient, and they have MacGyvered and come up with whatever they have to do to get to an outcome they need." In April 2026, Driscoll told Congress: "That being said, the civilian leadership, the design of our system, is that they get to pick the leaders that they want."

What's New

Additional reporting indicates that Driscoll launched the Army Transformation Initiative in May 2025, created the Army’s FUZE program, and launched the Army’s low-cost interceptor program. He stated in October 2025: "We will win with silicon and software and not our soldiers’ bodies… No one can predict the next war, but we cannot wait, we cannot fucking wait to innovate until Americans are dying on the battlefield." He stated in November 2025: "When you look at Ukraine, [they] have not accepted the current version of a thing as sufficient, and they have MacGyvered and come up with whatever they have to do to get to an outcome they need."

A source familiar with the matter stated: "Driscoll brought up concerns with the administration surrounding Army transformation and readiness and Hegseth’s blocking those efforts specifically by firing the generals who were responsible." The Pentagon hired conservative military veterans Rob Maness (retired Air Force colonel with more than 135,000 X followers) and Kurt Schlichter (retired Army colonel with 620,000 X followers) to work in Anthony Tata, the undersecretary of defense for personnel and readiness, as reported on August 31, 2026. The Department of Defense (referred to as the Department of War or DoW) published a notice on July 21, 2026, renewing the Board of Visitors, National Defense University, stating that this governance structure ensures compliance with the Goldwater-Nichols Department of Defense Reorganization Act of 1986's mandate to maintain rigorous standards for the military education of officers.
