Army Secretary Dan Driscoll has stepped down after 18 months on the job, leaving the Army without a Senate-confirmed secretary or chief of staff as leadership turnover under Defense Secretary Pete Hegseth continues to mount.
Driscoll spoke with President Trump about the current state of the Army and then submitted his resignation, a U.S. Army official told the Associated Press on Monday. The White House confirmed the departure but offered no explanation for why one of the administration's most broadly supported defense appointees, confirmed by the Senate 66, 28 in February 2025, was walking away barely a year and a half into his tenure.
White House spokeswoman Anna Kelly praised Driscoll in a statement, calling him "highly effective in advancing President Trump's agenda" and crediting 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." She added that "the United States Army is more powerful than ever thanks to his work alongside the Commander-in-Chief and Secretary of War."
The praise was generous. The silence on the reason was conspicuous. And the timing, amid months of widely reported friction between Driscoll and Defense Secretary Pete Hegseth, told its own story.
Driscoll's departure does not happen in isolation. It caps a stretch of senior leadership turnover at the Pentagon that has left the Army, specifically, without a Senate-confirmed secretary or a Senate-confirmed chief of staff. That is not a trivial gap. Newsmax reported that the resignation adds to a broader pattern of upheaval within the Defense Department under Hegseth's watch.
In April, Hegseth suddenly ousted Gen. Randy George, the Army's top uniformed leader and a Driscoll ally. Driscoll told Congress afterward that he and his family drove to George's house following the general's resignation, "and we all gave him a hug." He acknowledged the civilian leadership structure's authority, "the civilian leadership, the design of our system, is that they get to pick the leaders that they want", but the personal gesture said plenty about where his loyalties fell.
That same month, the Pentagon abruptly announced the departure of Navy Secretary John Phelan, the first head of a military service branch to leave during Trump's second term. Then in June, Gen. Christopher Donahue, the Army's commander in Europe and Africa, unexpectedly stepped down.
The pattern is hard to miss. Multiple senior Army officials have been fired or forced out under Hegseth's tenure. The Washington Examiner reported that Driscoll's resignation was driven by disagreements over Army transformation and readiness, specifically, Hegseth's decision to fire the very generals responsible for carrying out those efforts. The resignation takes effect September 3.
Driscoll was not a bureaucratic placeholder. He served as an Army armor officer from August 2007 to March 2011 and deployed to Iraq from October 2009 to July 2010. He later became a tech investor and an adviser to JD Vance, whom he met at Yale Law School. He ran unsuccessfully in a 2020 Republican primary for a North Carolina congressional seat, pulling roughly 8 percent of the vote.
When Trump nominated him in 2024, the president called Driscoll "a disruptor and change agent." The Senate agreed. His confirmation hearing was described as largely unconfrontational, and the 66, 28 vote reflected unusual bipartisan confidence. Breitbart noted that Driscoll served as the youngest-ever Army secretary.
That bipartisan goodwill showed up again in the reaction to his departure. Rep. Steve Womack, an Arkansas Republican who served in the Army National Guard, posted on X that Driscoll was "a transformative leader who brought common sense and discipline to the Department of the Army."
Womack added:
"I had the pleasure of working with him closely, and appreciated how engaged he was from mentoring cadets at West Point to leading the Army at the Pentagon. The Army is better equipped and prepared to tackle emerging threats because of his leadership that strengthened the force while putting our Soldiers first."
Even across the aisle, Driscoll drew praise. Rep. Jason Crow, a Colorado Democrat, former Army Ranger, and co-chair of the House Army Caucus, told reporters he valued working with Driscoll despite their policy differences.
"It was actually nice, I will say, having somebody who was smart, that knew the policy, that wanted to do the work, that had a background in these issues."
Crow then pivoted to criticism of the broader environment: "It's unfortunate that somebody like that can't last in this administration." He described the Pentagon as "in some cases, rudderless" and said he was "gravely concerned about it."
One concrete policy dispute illustrates the friction. Driscoll championed a drone and counter-drone modernization program, an initiative aligned with lessons from the ongoing conflicts reshaping modern warfare. But Gen. Christopher LaNeve, who replaced the ousted Gen. George as acting Army chief of staff and whose rise has been described as meteoric under Hegseth, moved in a different direction.
In August, LaNeve directed an Army unit in Europe to end its drone-building efforts and return to being a traditional infantry battalion. The decision effectively pulled the plug on a modernization program Driscoll had backed. Whether that order was a proximate cause of Driscoll's resignation is not confirmed, but the timing and the policy reversal fit the broader pattern of disagreement over the Army's direction.
Driscoll also served as a key negotiator in efforts to end the Russia-Ukraine war, a role the White House statement specifically highlighted. What happens to those negotiations now, and who, if anyone, picks them up, remains unclear.
The Washington Examiner reported that Hegseth is considering Sean Parnell, currently assistant secretary of defense for public affairs, as a potential replacement. No formal nomination has been announced.
Sen. Jack Reed, the Rhode Island Democrat who ranks as the top minority member on the Senate Armed Services Committee and is himself a former Army officer, issued a statement praising Driscoll for working "to transform the Army for the battlefield of the future" and engaging "with Congress candidly and consistently."
Reed then turned his criticism squarely on the defense secretary:
"Secretary Hegseth is cultivating a culture where dissent is punished and competence is secondary to personal allegiance."
Reed noted that "hundreds of thousands of soldiers are deployed around the world, many in combat zones." The implication was direct: leadership instability at the top of the Army is not an abstract management problem. It carries real consequences for troops in the field.
That criticism comes from a Democrat, and readers should weigh it accordingly. But the underlying facts, three senior Army leaders gone in roughly four months, a modernization program reversed, no confirmed secretary or chief of staff, are not partisan talking points. They are the documented record of a Defense Department in significant flux.
The White House statement treated Driscoll's exit as a success story. Kelly's language, "outstanding leadership," "readiness and lethality," "more powerful than ever", framed the departure as a mission accomplished. No friction was acknowledged. No successor was named.
The Pentagon, for its part, referred questions to the Army. That bureaucratic shuffle is standard, but it left the public explanation of a major leadership change in the hands of a department that now lacks a confirmed civilian leader.
Driscoll himself did not issue a public statement, at least not one captured in available reporting. His silence, combined with the White House's carefully positive framing, leaves the real reasons for his departure in the category of widely reported but officially unconfirmed. Tensions with Hegseth have been described across multiple outlets, but no one on the record has said plainly: this is why he left.
Hegseth's own political future has drawn separate attention. His recent Iowa fundraiser trip stirred speculation about post-Pentagon ambitions, raising questions about whether his management of the Defense Department is shaped by priorities beyond the military's immediate needs.
Meanwhile, the Army's leadership bench grows thinner. No confirmed secretary. No confirmed chief of staff. A drone modernization effort shelved. A pattern of internal resistance and reversed plans that has marked Hegseth's tenure from the start.
The men and women in uniform did not sign up for a revolving door at the top. They deserve steady, competent leadership, and right now, the Army does not have it.
