Army Secretary Dan Driscoll submitted his resignation on August 31, 2026, ending an 18-month run atop the Army’s civilian leadership that was defined by repeated collisions with Defense Secretary Pete Hegseth. He was expected to clear out of the Pentagon within days, and once he does, the Army will be left without a single Senate-confirmed leader, civilian or uniformed.
Fox News correspondent Jennifer Griffin reported that Driscoll walked away over “concerns with the administration surrounding Army transformation and readiness and Hegseth’s blocking those efforts specifically by firing the Generals who were responsible.”
The White House offered no hint of acrimony. White House spokesperson Anna Kelly said Driscoll had been highly effective in advancing President Donald Trump’s agenda at the Department of the Army, crediting him with leadership during major military operations, a renewed focus on readiness and lethality, and a role in negotiations between Russia and Ukraine. The Army, she added, is more powerful than ever because of his work.
A Feud That Spilled Into Public View
The rupture between the two men had been building for months, and its clearest flashpoint came in April, when Hegseth dismissed Army Chief of Staff Gen. Randy George without offering a reason. Driscoll, asked about the firing during Capitol Hill testimony that month, recalled that word reached him while he was away on a family vacation in North Carolina, and that they drove straight to George’s house. “We walked right in, and we all gave him a hug,” Driscoll testified, calling George a transformational leader with 42 years of service.
George was not an isolated case. When Hegseth took over the department in 2025, the Army had 10 four-star generals on active duty; it now has five, with Hegseth elevating officers viewed as closer to him. He also blocked promotions of Black and female Army officers whom Driscoll had backed. Those personnel fights were seen as the central source of the split between the two men, though not the only one.
The Drone Portfolio He Leaves Behind
Driscoll, now 40, served as an Army officer in Iraq and worked in venture capital before Trump named him the 26th secretary of the Army. He became the youngest person ever to hold the job in 2025, at age 38, arriving with a mandate to move fast on drones and other emerging technology — a focus that earned him the informal label of Trump’s “drone guy.” On June 10, 2025, he took the stage at Fort Bragg, North Carolina, during the festivities marking the Army’s 250th birthday.
But that portfolio has been getting smaller. The Pentagon announced in August that it would break up an Army drone unit based in Europe whose work centered on how Ukrainian forces used unmanned systems against Russia — a move that ran counter to the modernization drive Driscoll had made his calling card.
The post he is leaving behind is the service’s senior civilian role, carrying responsibility for personnel, the Army budget and long-range planning. Because the position falls outside the military chain of command, Driscoll gave no orders to the troops stationed throughout the Middle East, where the Army maintains a heavy presence.
Vance Ties and Pentagon Churn
Driscoll’s political lineage traces straight back to the vice president’s office. He and Vice President JD Vance both served in Iraq and met at Yale Law School, where they became close friends, and Vance championed his selection as Army secretary. Driscoll worked as a political adviser to Vance during the 2024 campaign, and well before the resignation, the press was rife with speculation that he would eventually leave the Pentagon for a Vance campaign.
His departure lengthens the roster of top officials who have left under Hegseth, a former “Fox & Friends Weekend” host who styles himself “secretary of war.” Also shown the door were John Phelan, the former Navy secretary, along with Gen. David M. Hodne and Maj. Gen. William Green Jr. Hegseth, 46, has telegraphed political aspirations of his own, teasing a potential 2028 White House bid with an unannounced August visit to Iowa. In April, a person close to the administration said Hegseth feared being dismissed and saw Driscoll as an obvious replacement.
Filling the vacuum will not be easy. Gen. Christopher LaNeve, who previously served as Hegseth’s military aide, is acting Army chief of staff, and Hegseth would like to make the arrangement permanent — though his nomination needs the backing of every Republican on the Senate Armed Services Committee to advance. As of August 31, Driscoll’s deputy undersecretary, Dave Fitzgerald, was also expected to resign before the week was out.
The timing has attracted scrutiny of its own. Libbey Dean, a NewsNation correspondent, posted footage of Hegseth leaving Washington’s Eisenhower Executive Office Building at roughly 5 p.m., just before word of the resignation became public. Driscoll’s exit also came after reports that a number of senior generals had formally lodged “non-concurs” with Hegseth’s orders, objecting to further military action in Iran. That is the backdrop for the vacancy now sitting atop the Army: a Pentagon cycling through its senior leaders while the war in Iran continues with no end in sight.
