In short
- The White House confirmed on August 31, 2026, that US Army Secretary Dan Driscoll submitted his resignation, adding another senior departure to a period of leadership change at the Pentagon.

The White House confirmed on Monday, August 31, 2026, that US Army Secretary Dan Driscoll had submitted his resignation to President Donald Trump, marking another senior departure from the Department of Defense.
White House spokesperson Anna Kelly credited Driscoll with advancing the administration’s military priorities, including Army readiness, modernization and work related to negotiations between Russia and Ukraine. The administration did not give a formal reason for his departure.
Reports by The Guardian and Al Jazeera said Driscoll’s exit followed apparent friction with Defense Secretary Pete Hegseth. That account has not been presented as the official explanation for the resignation.
Driscoll, an Iraq War veteran, technology investor and former adviser to Vice President JD Vance, was confirmed by the Senate in February 2025 by a 66-28 vote. During his tenure, he supported efforts to accelerate the Army’s development and procurement of drones and counter-drone systems.
His resignation comes during broader turnover in senior Army leadership. Army Chief of Staff Gen. Randy George was removed in April 2026, while Gen. Christopher Donahue, commander of US Army forces in Europe and Africa, stepped down in June.
The White House had not announced a successor in the source reports reviewed for this article.
