Six Months Into an Unwinnable War With Iran, the Army's Civilian Leader — Secretary Dan Driscoll — Abruptly Resigned After a Months-Long Turf War With Defense Secretary Hegseth, Who Had Already Fired the Army's Top General; His Exit Leaves the Army Without a Senate-Confirmed Civilian or Uniformed Leader in the Middle of the Fight, to Be Replaced, Hegseth Hopes, by a Pentagon Spokesman
On August 31, 2026, Army Secretary Dan Driscoll — the civilian leader of the U.S. Army since February 2025, an Army veteran and close friend of Vice President JD Vance — abruptly submitted his resignation, which Trump accepted, effective September 3. His departure caps months of friction with Defense Secretary Pete Hegseth over the direction of the Army and, above all, Hegseth's purge of its senior officers: in April, Hegseth fired the Army Chief of Staff, Gen. Randy George — with whom Driscoll worked closely — along with other generals, and pushed for tighter personal control over Pentagon messaging and policy. The timing is the alarming part. Driscoll is walking out six months into the war with Iran, a conflict that shows no sign of ending, with American troops deployed and the military stretched thin. Because Gen. George was already fired and now Driscoll is gone, the Army is left without a Senate-confirmed leader — civilian or uniformed — in the middle of a war. Hegseth's reported choice to replace Driscoll is Sean Parnell, the Pentagon's public-affairs chief and a political operative, whose path to Senate confirmation is uncertain. The picture is of a Defense Secretary who has spent his tenure purging commanders and consolidating control over messaging, and who has now driven out the Army's civilian head mid-war — trading experienced leadership for loyalty and communications, at the worst possible moment.
