Army Secretary Dan Driscoll has submitted his resignation to President Trump after months of reported friction with Defense Secretary Pete Hegseth, leaving the Army without a single Senate-confirmed civilian leader.

The White House confirmed Driscoll's departure on Monday, with spokesperson Anna Kelly praising his record but offering no explanation for the exit. Driscoll could leave as early as September 3, the Washington Examiner reported, making him the second military service secretary to depart the Pentagon in a matter of months.

No successor has been named. But the vacuum at the top of the Army's civilian chain of command comes at a moment when the service has also lost its top uniformed leader and its commander in Europe and Africa, all since April. For a branch responsible for the largest share of America's ground combat power, the leadership churn raises a straightforward question: who is running the Army?

Driscoll raised alarms about Hegseth's general firings before walking away

The resignation did not come out of nowhere. Driscoll had raised concerns directly with the White House about Hegseth's firing of senior Army generals, the New York Post reported, citing a Trump administration official. The core complaint: Hegseth was removing the very officers responsible for Army transformation and readiness, then blocking the modernization efforts those officers had been leading.

A source familiar with the matter told Fox News that Driscoll specifically accused Hegseth of hindering Army readiness "by firing the Generals who were responsible" for those initiatives.

The most prominent casualty was Gen. Randy George, the Army's top uniformed leader, whom Hegseth ousted in April. Driscoll told Congress he had deep respect for George and his 42 years of service:

"There is no person that has more respect for General George and his 42 years of service, his Purple Heart, his wife, Patty, their grandkids, their kids. I adore them, and he was an amazing, transformational leader."

Driscoll added that he and his family drove to George's house after the general's resignation "and we all gave him a hug." But he also acknowledged the civilian chain of command: "That being said, the civilian leadership, the design of our system, is that they get to pick the leaders that they want."

That deference did not save Driscoll's position. A Trump administration official told the Associated Press that tensions between Driscoll and Hegseth had been building for months. The New York Post's source was blunter: Hegseth and Pentagon chief of staff Ricky Buria "made it so untenable for him that he felt it was best for not just him but for the people that he loved and respected in the Army to leave."

Leak accusations and internal harassment preceded the exit

Part of what made Driscoll's position untenable, the Post's source said, was an accusation that he had leaked reports about low munitions stockpiles. The allegation was made without evidence, and no serious investigation followed.

A Trump administration official dismissed the charge outright: "It was such an absurd accusation that nobody seriously investigated it or took it seriously." But the accusation itself served a purpose, it poisoned the working relationship between the Army's civilian leader and the Pentagon front office.

The pattern fits a months-long rift that had been building between Driscoll and Hegseth's inner circle. Driscoll, an Iraq war veteran and former tech investor, had arrived at the Pentagon with a mandate from Trump himself, who called him "a disruptor and change agent" when nominating him in 2024.

The Senate agreed. Driscoll was confirmed 66-28 in February 2025, following what was described as a largely unconfrontational Armed Services Committee hearing. That bipartisan margin suggested broad confidence in his ability to lead the Army.

Drone modernization program scrapped as Driscoll headed for the door

One concrete casualty of the leadership upheaval: a drone modernization program Driscoll had championed. Driscoll had worked to cut red tape for military contractors developing drones and counterdrone capabilities, a priority that aligned with lessons from the battlefields of Ukraine.

But Gen. Christopher LaNeve, who replaced George as acting Army chief of staff after George's ouster, moved in a different direction. Officials said LaNeve directed an Army unit in Europe to end its drone-building efforts and return to being a traditional infantry battalion. The decision came the same week as Driscoll's departure.

LaNeve's rapid elevation under Hegseth and his decision to reverse a Driscoll priority illustrate the broader dynamic at work. Hegseth has been reshaping the Army's officer corps to match his vision, but that vision has come at the cost of the civilian secretary who was supposed to be implementing the president's agenda.

A Pentagon losing leaders faster than it can replace them

Driscoll is not the first service secretary to leave. Navy Secretary John Phelan departed in April after the Pentagon abruptly announced his exit, making him the first head of a military service to go during Trump's second term. Driscoll is now the second.

The general-officer ranks have thinned even faster. Gen. George was ousted in April. Gen. Christopher Donahue, the Army's commander in Europe and Africa, unexpectedly stepped down in June. Hegseth removed several other generals and admirals beyond those named publicly.

Sen. Jack Reed, the ranking Democrat on the Senate Armed Services Committee, framed the departures as a loyalty test gone wrong:

"Secretary Hegseth is cultivating a culture where dissent is punished and competence is secondary to personal allegiance."

Rep. Jason Crow, a Colorado Democrat and former Army Ranger, put it more starkly: "The Pentagon right now is, in some cases, rudderless, with so many senior leaders gone. So, I'm gravely concerned about it."

Those are Democratic voices, and their framing should be weighed accordingly. But the factual premise underneath their complaints is harder to dismiss. The Army currently has no Senate-confirmed secretary, no permanent chief of staff, and has lost its European theater commander, all within roughly five months.

Hegseth is reportedly considering Sean Parnell, the assistant secretary of defense for public affairs, as Driscoll's replacement, a choice that would install a Hegseth loyalist atop the Army's civilian leadership.

Driscoll's path from Yale Law to the Army's top civilian job

Driscoll's background set him apart from the typical Pentagon appointee. He served as an armor officer from August 2007 to March 2011, deploying to Iraq from October 2009 to July 2010. His father and grandfather also served in the Army.

After leaving the military, Driscoll became a tech investor and befriended JD Vance at Yale Law School, later serving as an adviser to the future vice president. He ran unsuccessfully in a 2020 Republican primary for a North Carolina congressional seat, earning roughly 8 percent of the vote in a crowded field.

The White House statement on his departure was warm but generic. Kelly called Driscoll "highly effective in advancing President Trump's agenda" and credited him with "providing outstanding leadership during historic military operations, restoring an emphasis on readiness and lethality, assisting with negotiations between Russia and Ukraine, and more."

Kelly added: "The United States Army is more powerful than ever thanks to his work alongside the Commander-in-Chief and Secretary of War."

Whether the Army is actually more powerful is an open question. The service lost its top civilian leader, its top uniformed leader, its European commander, and a drone modernization program, all in the span of a few months. Those are not the hallmarks of an institution gaining strength.

Driscoll himself, in a statement from April, struck a different tone than a man being pushed out: "Serving under President Trump has been the honor of a lifetime, and I remain laser focused on providing America with the strongest land fighting force the world has ever seen."

The broader question of Hegseth's own tenure has been a subject of Washington speculation for months. The Pentagon referred questions about Driscoll's departure to the Army, which had not responded to requests for comment at the time of the initial reporting.

Reforming the Pentagon is a worthy goal, and presidents have every right to choose their leaders. But reform that clears the building of competent people willing to disagree is not reform, it is consolidation. And the Army, which exists to fight and win wars, deserves better than a leadership vacuum dressed up as a shakeup.
