US Army Secretary Dan Driscoll resigns following Pentagon disagreements with Pete Hegseth

Resignation at the Pentagon

United States Army Secretary Dan Driscoll submitted his resignation to President Donald Trump on 31 August 2026, concluding an 18-month tenure as the service's top civilian official. Driscoll met in person with Trump on Monday to deliver his decision and discuss the state of the Army, following months of friction with Defense Secretary Pete Hegseth. Driscoll, an Iraq war veteran and technology investor who attended Yale Law School alongside Vice President JD Vance, was nominated in 2024 and confirmed to the post in February 2025. Trump had originally described Driscoll as a disruptor focused on reforming military procurement. During his time in the role, Driscoll was also assigned to assist in diplomatic negotiations between Russia and Ukraine.

White House spokeswoman Anna Kelly issued a statement commending his tenure:

Secretary Driscoll has been highly effective in advancing President Trump's agenda to Make America Strong Again at the Department of the Army by providing outstanding leadership during historic military operations, restoring an emphasis on readiness and lethality, assisting with negotiations between Russia and Ukraine, and more.

Clashes over commanders and drone strategy

The departure follows a series of personnel changes and tactical disagreements across the military's senior ranks. In April 2026, Hegseth dismissed Army Chief of Staff Gen. Randy George without public explanation, prompting Driscoll and his family to visit George at his home to offer support. Lawmakers from both parties voiced dismay at George's removal, but Driscoll testified to Congress that civilian authorities retain authority over personnel decisions:

That being said, the civilian leadership, the design of our system, is that they get to pick the leaders that they want.

In June 2026, the commander of American army forces in Europe and Africa, Gen. Christopher Donahue, also stepped down unexpectedly. Hegseth forced out at least three senior officers who had been considered potential successors to George, installing Gen. Christopher LaNeve as acting chief of staff.

Strategic priorities diverged between Driscoll and Pentagon leadership regarding weapons acquisition and technological adaptation. Driscoll had pushed the Army to acquire cheaper systems quickly, directing sharp criticism at established defense contractors:

The defense industrial base broadly, and the primes in particular, conned the American people and the Pentagon and the Army.

Under LaNeve, the service reversed course on a drone modernization program that Driscoll had championed. A European-based Army unit that had been developing its own unmanned aircraft was instructed to halt those operations and return to traditional infantry duties.

Operational strain and succession

Driscoll's exit leaves the Army without a confirmed civilian secretary or a permanent chief of staff at a time of heavy operational commitments. Army air defense units are currently deployed to protect American positions in the Middle East from Iranian missile attacks, while European command continues to supply intelligence and support to Ukraine against Russian forces. With midterm congressional elections approaching, confirming a replacement through the Senate may present logistical difficulties. Hegseth has voiced support for Pentagon chief spokesman Sean Parnell to fill the civilian vacancy, though Parnell faces scrutiny following the dismissal of three journalists from Stars and Stripes who subsequently filed a federal lawsuit against the government.
