Driscoll offers no reason for his exit as Army secretary but says Wednesday is his last full day

Dan Driscoll announced that Wednesday would be his last full day as U.S. Army secretary, but offered no explanation for his departure after 18 months as the service’s civilian leader.

In a post on X, Driscoll called the job “the honor of a lifetime” and praised soldiers, their families and the Army’s civilian workforce. He said they had helped “modernize and accelerate how the Army mans, trains, and equips the most lethal fighting force on the face of the earth.” He also credited Defense Secretary Pete Hegseth, saying, “We could not have made the progress we did without the support of Secretary Hegseth.”

Driscoll’s exit comes amid widely reported tensions with Hegseth. President Donald Trump’s Pentagon chief ousted several of Driscoll’s allies this year, including Army Chief of Staff Gen. Randy George. Gen. Christopher LaNeve became acting chief and recently ended a drone modernization program that Driscoll had championed.

The departure also comes as U.S. forces resume airstrikes against Iran after a lull in hostilities during a war that has lasted more than six months. It was not immediately clear who would temporarily replace Driscoll. A bipartisan group of lawmakers has asked the Army to explain the decision to eliminate the specialized drone unit.

Driscoll had pushed to reduce bureaucratic delays so military contractors could develop drones and counter-drone systems more quickly. The administration also assigned him last year to help negotiate an end to the Russia-Ukraine war. White House spokeswoman Anna Kelly highlighted that role when confirming his resignation.
