Army Secretary Dan Driscoll Resigns After Months of Clashes with Defense Secretary Hegseth
Army Secretary Dan Driscoll has resigned after just 18 months on the job, the White House confirmed Monday, marking the latest high-profile departure in a Pentagon leadership increasingly defined by turmoil. Driscoll submitted his resignation directly to President Donald Trump, who accepted it Monday evening, according to NPR.
The resignation follows months of reported clashes between Driscoll and Defense Secretary Pete Hegseth over the firing and sidelining of senior military officers—a conflict that sources say Driscoll repeatedly brought to the White House’s attention.
A Leadership Vacuum at a Critical Moment
Driscoll’s departure leaves the Army without a Senate-confirmed civilian or uniformed leader as the Iran war enters its seventh month. Hegseth fired Army Chief of Staff Gen. Randy George in April without explanation, and no successor has been named, as Stars and Stripes reported.
“This is a big hit to the Army,” one senior defense official said, speaking on condition of anonymity. The official told ABC News that Driscoll had served as a buffer between Hegseth and the Army, particularly by pushing back through the White House on Hegseth’s purge of senior officers—even if those efforts ultimately did little to slow it.
A Pattern of Friction
The tensions between Driscoll and Hegseth were not new. When Hegseth took office, the Army had 10 four-star generals on active duty; today it has five. More than two dozen senior U.S. military officers have been fired or sidelined by Hegseth without public explanation.
In April, Hegseth dismissed Gen. Randy George, the Army’s top officer and a close ally of Driscoll, without giving a reason. Driscoll testified before Congress that month that he learned of George’s firing while on vacation in North Carolina and drove to the general’s home with his family.
“We walked right in, and we all gave him a hug,” Driscoll said in his congressional testimony. “There is no person that has more respect for Gen. George and his 42 years of service. He was an amazing, transformational leader.”
Hegseth also blocked promotions of Black and female Army officers who had Driscoll’s support, according to multiple reports. Sources told ABC News that Driscoll had warned White House Chief of Staff Susie Wiles about what he described as Hegseth’s “widespread and seemingly indiscriminate firing of senior military officers.”
When Driscoll spoke with Trump about his resignation, he told the president that Hegseth’s chaotic removal of experienced leaders was “hurting the force and shrinking the pool of officers available for future senior commands,” according to sources familiar with the conversation. Trump appeared surprised by the extent of the problem, one source said.
An Unconventional Rise
Driscoll arrived at the Pentagon as an unconventional choice. A third-generation soldier from North Carolina, he served in the Army from 2007 to 2010 as a cavalry officer with the 10th Mountain Division and deployed to Iraq in 2009. He left the service as a first lieutenant before attending Yale Law School, where he met and befriended JD Vance.
After working in venture capital and investing in defense technology startups, Driscoll ran unsuccessfully for Congress in 2020 before serving as a political adviser to Vance during the 2024 campaign. Trump nominated him as Army Secretary in December 2024, calling him “a disruptor and change agent.”
The Senate confirmed Driscoll on February 25, 2025, by a 66-28 vote, making him the youngest-ever Army Secretary at age 38, as AP News reported at the time.
Despite his lack of national security experience, Driscoll quickly became one of the most popular figures in national security circles, earning bipartisan support on Capitol Hill. He was known as Trump’s “drone guy” for his focus on modernizing the Army through new technologies, and he worked with Democrats including Sen. Elizabeth Warren on right-to-repair reforms.
Trump also tapped Driscoll for an unusual diplomatic role—leading peace negotiations between Russia and Ukraine, a task beyond the normal scope of a service secretary. Driscoll traveled to Kyiv in November 2025 and later led talks in Abu Dhabi with a Russian delegation.
Broader Pentagon Turmoil
The resignation comes amid broader upheaval across the Department of Defense. Navy Secretary John Phelan was abruptly forced out in April. In June, Gen. Christopher Donahue, commander of Army forces in Europe and Africa, unexpectedly stepped down. The Pentagon recently announced the dismantling of an Army drone unit in Europe that had been studying Ukraine’s drone successes against Russia.
The churn has continued as the Iran war grinds on with no end in sight. As Middle East Eye reported, the heads of the Army, Navy, and Air Force, along with four-star commanders overseeing U.S. operations throughout Europe, Asia, and Latin America, have warned Hegseth that prolonging major operations would weaken America’s ability to confront other adversaries.
The war has also caused a “beyond critical” shortage of advanced missile interceptors, and the U.S. has virtually exhausted its stockpile of sophisticated long-range missiles.
Official Reactions
In a statement, White House spokesperson Anna Kelly praised Driscoll, saying he had been “highly effective in advancing President Trump’s agenda to Make America Strong Again at the Department of the Army” and noting his work “assisting with negotiations between Russia and Ukraine.”
Kelly also expressed confidence in Hegseth, saying, “The President has complete trust in Secretary Hegseth, who is doing an incredible job leading the Pentagon,” adding that results in recent military operations, including the war in Iran, “speak for themselves.”
Pentagon spokesperson Sean Parnell, an Army veteran widely viewed as a potential replacement for Driscoll, defended Hegseth’s approach, saying he “communicates with the president daily and is grateful to serve a commander-in-chief who loves our military.”
What’s Next
The Army now faces the challenge of operating without permanent civilian or uniformed leadership during an active conflict. Pentagon spokesperson Sean Parnell is widely viewed as a potential successor to Driscoll, though he would likely face a difficult confirmation fight.
Driscoll’s close relationship with Vice President JD Vance—widely considered a 2028 presidential hopeful—had long fueled speculation that he would eventually leave to join a Vance campaign. His resignation now opens the door to that possibility.
For now, the question of who will lead the Army through the Iran war remains unanswered, as does the broader question of how much longer Hegseth’s purge of senior military leadership will continue. As former Air Force Secretary Frank Kendall wrote in a recent New York Times op-ed, the silence of senior officers in the face of these changes “is a cop-out, and it is putting our democracy at risk.”
The Guardian noted that Driscoll’s exit is part of a pattern of high-level departures that have left the Pentagon’s civilian leadership in a state of constant flux, even as U.S. forces remain engaged in combat operations abroad.
