US Army Secretary Dan Driscoll resigns after 18 months amid Pentagon tensions

Dan Driscoll, one of the highest-ranking civilian leaders in the US Army, walked away from his post after eighteen months. No official explanation was offered for his departure, though tensions between him and Defense Secretary Pete Hegseth have been the subject of widespread reporting in recent weeks.

Driscoll, who counts Vice-President JD Vance among his close associates, submitted his resignation following a conversation with President Trump about the state of the army. An unnamed Pentagon official confirmed the basic facts but declined to elaborate. The White House statement credited Driscoll with advancing Trump's agenda to strengthen America, pointing to his work on military readiness, lethality, and negotiations aimed at ending the Russia-Ukraine conflict. The resignation was first reported by The Wall Street Journal.

The timing of Driscoll's exit sits within a broader pattern of military leadership upheaval. General Randy George, the army's top uniformed officer and an ally of Driscoll's, was abruptly removed in April. General Christopher Donahue, who commanded forces in Europe and Africa, stepped down unexpectedly in June. General Christopher LaNeve, who has risen rapidly under Hegseth's watch, assumed George's role as acting chief of staff. When Driscoll testified before Congress about George's ouster, he described driving to the general's home with his family to offer support, though he acknowledged that civilian leadership has the authority to select military commanders.

Driscoll's departure also follows the cancellation of a drone modernization program he had championed. An army unit stationed in Europe had been developing its own drones before LaNeve ordered the effort halted, redirecting the unit back to traditional infantry operations. This reversal signals a significant shift in the army's technological priorities under the current Pentagon leadership.

Before taking the Army Secretary role, Driscoll was an Iraq war veteran, technology investor, and former adviser to Vance, whom he met at Yale Law School. Trump nominated him in 2024, describing him as "a disruptor and change agent." The Senate confirmed him in February 2025 by a vote of 66 to 28, following a hearing that focused largely on military modernization, recruitment challenges, and strengthening the defense industrial base. Driscoll served as an armor officer from 2007 to 2011 and deployed to Iraq from late 2009 through mid-2010. He also ran unsuccessfully in the 2020 Republican primary for a North Carolina congressional seat, capturing roughly 8 percent of the vote in a crowded field.

As Army Secretary, Driscoll held an unusual dual role as a key negotiator attempting to broker peace between Russia and Ukraine. He also pushed aggressively to streamline bureaucratic processes so military contractors could rapidly develop drone and counter-drone systems as global warfare tactics evolved. His departure comes amid broader concerns about military strain. The USS Abraham Lincoln, an aircraft carrier, was deployed for a record 250 days during ongoing operations against Iran, experiencing supply shortages and triggering mental health concerns among its crew before being ordered to return home. Military leaders have warned Hegseth against prolonging large-scale operations against Iran, citing concerns that US military capacity is stretched thin globally and munitions stockpiles are being depleted.

Driscoll's resignation is the latest in a series of departures from senior military posts. Navy Secretary John Phelan was forced out in April after being told by Hegseth to resign or face termination, serving in the role for less than a month. His departure marked the first time a head of a military service left during Trump's second term. As the conflict with Iran continues past the six-month mark, questions about the sustainability of current military commitments remain unresolved.
