Army Secretary Driscoll Resigns After 18 Months Amid Hegseth Tensions

Army Secretary Dan Driscoll submitted his resignation to President Trump on Monday, ending an 18-month tenure marked by efforts to reshape the service's structure and priorities. The move comes amid reported tensions inside the Pentagon and leaves the Army without Senate-confirmed leadership at a moment when U.S. forces remain engaged in operations against Iran.

Driscoll, the youngest person to hold the post, had pushed an initiative aimed at consolidating the Army's Futures Command and Training and Doctrine Command while scaling back programs such as the AH-64D Apache helicopter, the M10 Booker combat vehicle, and the Gray Eagle drone. Supporters described the changes as necessary to shift resources toward newer technologies and improve readiness. Critics inside the building viewed them as disruptive to established acquisition processes and force structure.

Two factors appear to have driven the decision. One was frustration that the modernization agenda was encountering resistance from senior Defense Department officials. The other was the turbulence created by the earlier dismissal of Army Chief of Staff Gen. Randy George, a move that removed a key uniformed partner for Driscoll's plans. People familiar with the discussions said Driscoll recently conveyed his concerns directly to the president and concluded that his departure was the appropriate step, even after White House officials asked him to remain until after the midterms.

Driscoll's relationship with Defense Secretary Pete Hegseth had grown strained over time. Officials described Hegseth as wary of Driscoll's close ties to Vice President JD Vance, a Yale Law School classmate. That personal connection, combined with differing views on how quickly and how far to push institutional changes, contributed to an atmosphere of suspicion at the top of the department.

The White House offered a positive assessment of Driscoll's record, crediting him with restoring emphasis on readiness and lethality and assisting diplomatic efforts between Russia and Ukraine. Driscoll's background as an Army veteran who deployed to Iraq in 2009 and his prior work on emerging technologies gave him standing among some officers and lawmakers who viewed him as a credible advocate for updating the force.

Still, the cumulative effect of leadership turnover at the Army's highest levels has created uncertainty. With no confirmed civilian secretary and no confirmed chief of staff, day-to-day direction now falls to acting officials during an active period of military operations. How the service proceeds with the broader transformation agenda Driscoll championed will depend on whom the administration selects next and how much latitude that person receives from the Defense Department.
