"Secretary Driscoll has been highly effective in advancing President Trump’s agenda to Make America Strong Again at the Department of the Army..." Anna Kelly, a White House spokesperson, said in a statement to Breaking Defense and The Wall Street Journal.
Dan Driscoll resigns after less than two years as Army secretary
Dan Driscoll, the 26th secretary of the Army, has submitted his letter of resignation after serving in the job for under two years, two Army officials told Breaking Defense. The officials said Driscoll tendered his resignation after speaking with President Donald Trump about the state of the Army, though the official did not elaborate. The move follows multiple reports that he would exit before the end of the year — possibly as soon as Labor Day.
Conversation with President Donald Trump and White House response
Breaking Defense attributed Driscoll’s resignation in part to a conversation with President Donald Trump, according to an Army official. A spokesperson for the Army declined to comment and referred questions to the White House; the Pentagon also declined to comment and referred Breaking Defense to the Army. Anna Kelly, speaking for the White House, praised Driscoll’s leadership and credited him with advancing the president’s agenda, restoring “an emphasis on readiness and lethality,” and “assisting with negotiations between Russia and Ukraine,” adding, “The United States Army is more powerful than ever thanks to his work alongside the Commander-in-Chief and Secretary of War.”

Get a security leadTenuous relationship with Defense Secretary Pete Hegseth
Driscoll’s departure comes amid months of reports about a strained relationship with Defense Secretary Pete Hegseth. Reporting cited in Breaking Defense noted that the reported tension grew after Driscoll traveled with Army Chief of Staff Gen. Randy George to Ukraine last year for ceasefire negotiations and to study drone-warfare lessons — an arrangement that The Hill reported seemingly agitated Hegseth. The Wall Street Journal additionally reported that Hegseth was unhappy after Driscoll began arranging plans to have Vice President JD Vance and President Trump meet soldiers and discuss further Army reform.
Succession options: Michael Obadal, acting appointees, and Senate-confirmation gaps
It is not immediately clear who will replace Driscoll. An Army official told Breaking Defense that “usually” the service’s undersecretary, Michael Obadal, would step into the role. The official also said Obadal and Hegseth “have a great working relationship.” At the same time, Hegseth could appoint any qualified official to an acting role and would be under no obligation to install Obadal as acting secretary or as a nominee for the full post.
Driscoll’s exit leaves the Army without a Senate-confirmed civilian leader at a time when the service’s senior uniformed leadership also lacks permanent confirmation. The Army’s Vice Chief of Staff, Gen. Christopher LaNeve, is serving as Army chief in an acting capacity and has not been nominated or confirmed for the role. The Wall Street Journal reported that LaNeve faces expected Democratic opposition and does not have full support from some Republican lawmakers, including Sen. Joni Ernst of Iowa.
The Washington Post reported in April that Sean Parnell, the Pentagon’s chief spokesman, had told colleagues he is interested in the job following the abrupt firing of the Army’s former chief of staff, Gen. Randy George — a development raised by Breaking Defense as part of the broader personnel turbulence.
Programmatic legacy: FUZE and the low-cost interceptor effort
During his tenure Driscoll pushed commercial practices into the service, drawing on his private equity and venture-capital background. He publicly framed disruptive change to large defense primes as desirable — at one point saying it would be a “success” if a large prime contractor closes its doors in the coming years because it cannot operate more efficiently.
Driscoll launched an Army low-cost interceptor program intended “to produce scalable, affordable interceptors in an effort to end the days of relying solely on multimillion-dollar systems, mainly manufactured by large defense primes, to down drones costing a couple thousand dollars.” He also created the Army’s FUZE program, described as “a venture-capital-like acquisition model designed to speed up the private development of emerging technologies for later use by soldiers.”
What this means for Michael Obadal, Pete Hegseth, and the Senate
- Michael Obadal: As undersecretary, Obadal is the internal, usual successor named by an Army official. He will be watched as a continuity option for programs such as FUZE and the low-cost interceptor effort.
- Pete Hegseth: The defense secretary retains authority to appoint an acting secretary of the Army and could use that authority to shape the service’s civilian leadership and procurement direction.
- The Senate and nominees: With Gen. Christopher LaNeve serving in an acting military capacity and no confirmed Army secretary, congressional confirmation dynamics — including reported opposition from some Democrats and Republicans — will shape whether an acting arrangement becomes permanent or whether a new nominee faces prolonged scrutiny.
Dan Driscoll’s resignation crystallizes a period of rapid personnel churn and contested authority inside the Army and the Pentagon. How Hegseth, Obadal, LaNeve and Capitol Hill respond in days and weeks ahead will determine whether Driscoll’s procurement experiments — FUZE and the low-cost interceptors among them — gain steady footing or become points of contention in the service’s leadership transition. This is a developing story.
