US Army Secretary Dan Driscoll has resigned, becoming the latest senior figure to leave the Trump administration amid a reported feud with Defense Secretary Pete Hegseth. The White House announced the departure on Monday, framing it as a planned exit after a successful tenure, though reports had suggested for months that Driscoll could step down before the end of the year. His resignation deepens uncertainty at the Pentagon, which is already grappling with leadership gaps and tension surrounding Hegseth.

Driscoll reportedly clashed with Hegseth over the blocking of promotions for several Army officers and the April removal of Randy George, the Army's Chief of Staff and a close Driscoll ally, whose ousting left the Army without a Senate-confirmed leader. General Christopher LaNeve, a former Hegseth aide, has been serving as interim replacement. Sources have suggested Hegseth's moves were driven by concern that Driscoll, seen as close to Vice President JD Vance, could be positioned to succeed him, with tensions linked back to the March 2025 "Signalgate" scandal. Driscoll is expected to officially leave his post within days.
