Dan Driscoll resigned as secretary of the Army on Aug. 31, 2026. His departure leaves the Army without a Senate-confirmed civilian leader six months into the war with Iran, its busiest period since the wars in Iraq and Afghanistan.
Driscoll’s resignation was reportedly motivated, at least in part, by his frustration with Defense Secretary Pete Hegseth. Earlier in August, Hegseth had blocked the promotions of four Army officers.
