Dan Driscoll, the Army Secretary who won Senate confirmation with broad bipartisan support, is eyeing a departure from the Pentagon by year's end after a protracted power struggle with Defense Secretary Pete Hegseth, a clash that has already cost the Army its top general.
Driscoll has told associates he expects his tenure to last between 23 and 24 months, and sources familiar with the discussions say he plans to step down around the end of 2026. The Hill reported that the anticipated exit follows a simmering turf war between Driscoll and Hegseth that escalated late last year when President Trump tapped Driscoll, not Hegseth, to negotiate directly with Ukrainian officials in hopes of ending the Russia-Ukraine war.
The move put Driscoll, a former venture capitalist and close ally of Vice President Vance, squarely in Hegseth's crosshairs. What followed was a months-long struggle for influence inside the Pentagon that has disrupted Army leadership, stalled key confirmations, and raised questions about whether internal rivalries are undermining military readiness at a moment when the service branch is trying to modernize for the next fight.
The sharpest flashpoint came in early April, when Hegseth ousted Gen. Randy George from his post as Army Chief of Staff. George, who had been nominated under the Biden administration and confirmed by the Senate in 2023, was expected to serve a four-year term through roughly 2027. Hegseth called George and demanded his immediate retirement, telling him it was "time for a leadership change in the Army," Fox News reported.
George was not the only one pushed out. Hegseth also demanded resignations from Gen. David Hodne and Maj. Gen. William Green, moves that sources described as a targeted purge of officers perceived to be loyal to Driscoll. The New York Post reported that Hegseth's actions were driven by personal insecurity following the Signalgate episode, and by his fear that Driscoll was positioning to replace him as Defense Secretary.
An unnamed administration official put it bluntly:
"This is all driven by the insecurity and paranoia that Pete has developed since Signalgate. Unfortunately, it is stoked by some of his closest aides who should be trying to calm the waters."
A source close to the Trump administration offered a similar account, saying Hegseth "is very concerned about being fired and he knows that Driscoll is one of the top contenders, or a natural contender, to succeed him. So what Pete has been doing is taking anyone he perceives to be close with Driscoll and going after them."
Driscoll's office was reportedly caught off guard by the personnel moves. He did not sit quietly afterward. The Washington Examiner reported that Driscoll visited George at his home after the forced retirement, publicly praising the ousted general's 42 years of service.
"We walked right in, and we all gave him a hug. There is no person that has more respect for General George and his 42 years of service."
That kind of open loyalty to a general Hegseth had just fired was not subtle. Driscoll, at the time, said he had no plans to resign. Now, months later, the exit timeline has come into sharper focus.
The stakes extend well beyond personality conflicts. Driscoll and George had co-launched the Army Transformation Initiative, a sweeping effort to "deliver critical warfighting capabilities, optimize our force structure and eliminate waste and obsolete programs." The initiative focused on integrating drones and artificial intelligence into Army formations, lessons drawn directly from watching Ukrainian forces use commercial technology to devastating effect against Russian armor and infantry.
Driscoll pushed the Army to improve living conditions for service members and modernize equipment. Sources described him as "aggressive" in securing buy-in from general officers to deliver results within his limited window. He understood his time was short and moved accordingly.
But with George gone and Driscoll heading for the door, the future of that transformation effort is uncertain. The Army is already planning to phase out a battalion under the 173rd Airborne Brigade that had been studying and incorporating lessons from overseas wars, including the use of unmanned systems in the Russia-Ukraine conflict. That unit, backed by George and former U.S. Army Europe and Africa commander Gen. Chris Donahue, represented exactly the kind of battlefield adaptation the Transformation Initiative was designed to accelerate.
Shuttering a unit focused on drone warfare lessons, at a time when every serious military analyst recognizes unmanned systems as central to modern combat, raises an obvious question: Is the Army making decisions based on warfighting priorities, or on internal politics?
Hegseth and Trump moved to install Gen. Christopher LaNeve as the Army's acting Chief of Staff after George's removal. LaNeve, described as a former military aide to Hegseth, has met with senators in recent months. But his path to full confirmation is far from clear. Bipartisan lawmakers have raised objections, and the nomination remains in question.
Rep. Tom Cole, the Oklahoma Republican who chairs the House Appropriations Committee, called George's departure "a real loss to us, in my opinion", a pointed remark from a senior member of the president's own party. When GOP appropriators are publicly lamenting the removal of an Army chief, the personnel decisions deserve scrutiny.
Driscoll himself won confirmation on a 66-28 Senate vote, a comfortable margin that reflected genuine bipartisan confidence in his ability to lead the Army. His background as a venture capitalist, his friendship with Vance dating back to Yale Law School, and his willingness to push modernization gave him credibility with both defense hawks and reform-minded conservatives. That credibility made him effective. It also, apparently, made him a threat.
The White House has reportedly blocked Hegseth from firing Driscoll directly, which suggests the administration recognizes the political cost of pushing out a Vance ally who has been an effective advocate for service members. Hegseth's top spokesman, Sean Parnell, has been floated as a potential replacement for Driscoll if the Army Secretary were ultimately forced out, a detail that speaks to how deeply the succession question has permeated Hegseth's inner circle.
Driscoll's spokesperson declined to comment on the expected departure. The Wall Street Journal had previously reported the anticipated exit.
None of this is happening in a vacuum. The Army is trying to absorb hard-won lessons from the largest land war in Europe since 1945. It is trying to integrate new technology, restructure its formations, and prepare for the possibility of conflict with a near-peer adversary. Every month spent on internal power struggles is a month not spent on those priorities.
Service members and their families, the people who actually bear the consequences of Pentagon leadership decisions, deserve better than a Defense Department consumed by turf battles. If Driscoll's departure is indeed coming, the administration owes the Army a successor who can pick up the modernization effort and run with it, not one chosen primarily for loyalty to whoever wins the next round of bureaucratic maneuvering.
Troops don't care who sits in which corner office at the Pentagon. They care whether the institution is serious about giving them what they need to fight and win. Right now, the evidence suggests the building is more focused on itself than on them.
