Army Secretary Dan Driscoll has submitted his resignation to President Trump, with a senior U.S. official confirming the move after 18 months of service marked by reform efforts and friction with the Pentagon leadership.
Army Secretary Dan Driscoll has submitted his resignation to President Donald Trump, a senior U.S. official confirmed. The resignation remains pending and has not yet been accepted by the White House, the official said.
Driscoll is expected to depart the Pentagon in the coming days, and his exit comes after roughly 18 months at the helm of the Army. The move follows a period of reported tension between Driscoll and Defense Secretary Pete Hegseth over the service's direction, according to reporting from The Wall Street Journal.
Driscoll brought a rare combination of military and business experience to the Pentagon. He served in the Army, including a deployment to Iraq in 2009, and completed Army Ranger School. He later earned a law degree from Yale, where he met Vice President JD Vance, and worked in finance before entering public service.
A North Carolina native, Driscoll ran for Congress in 2020 before joining Trump's 2024 presidential campaign as a senior adviser. President Trump nominated him for Army secretary that fall, describing him as a disruptor and change agent. The Senate confirmed Driscoll 66-28 in February 2025, and he has served since.
Before the nomination, Driscoll built a career at the intersection of the military, law, and technology. He is a graduate of the University of North Carolina, one of only a handful of Tar Heels to ever lead the Army, and his tenure has been defined by the same reform instincts he brought from the private sector.
The resignation follows months of reported friction between Driscoll and Hegseth over the Army's direction. The tension centered on how aggressively to push reforms through the service's sprawling bureaucracy and how quickly the Army should shed legacy programs in favor of modern capabilities.
Despite the internal disagreements, Driscoll's tenure saw real progress on the administration's defense priorities. He pressed for a renewed focus on warfighting readiness, pushed to modernize Army aviation and long-range fires, and worked to cut wasteful programs that had accumulated over decades. His willingness to challenge the Pentagon's massive acquisition system earned him a reputation as a reformer inside the building.
Observers noted the irony that the very energy that made Driscoll effective -- an insistence on speed, accountability, and results -- also put him on a collision course with the Pentagon's traditional power centers. In the end, the administration's push for change moved faster than the institution was prepared to accept.
Driscoll arrived with a mandate to shake up an institution that critics said had grown comfortable with process over results. As a combat veteran himself, he pressed for changes designed to benefit soldiers in the field rather than contractors and bureaucrats in the rear.
He also played a visible role in the administration's broader national security posture, including early work related to Ukraine that drew on his background as a tech investor and his military service. Colleagues described him as focused, direct, and willing to take on entrenched interests to get things done.
His departure marks the latest turnover in a Pentagon that the administration has pushed relentlessly to modernize, streamline, and refocus on great-power competition. Driscoll's reform push helped set the table for that effort, and his successor will inherit a service mid-reset.
The White House has not yet accepted the resignation, and no replacement has been announced. With Driscoll expected to step aside in the coming days, attention will turn to who President Trump taps next to lead the Army.
Whoever takes the job inherits a service in the middle of a generational reset, with the administration demanding leaner budgets, faster modernization, and a sharper focus on the threats that actually matter. Driscoll's tenure helped establish that direction, and the next Army secretary will be expected to keep the momentum going.
