US Army Secretary Dan Driscoll resigns amid reported tensions with Hegseth
Dan Driscoll, Army Secretary since January 2025, submitted his resignation on Monday after reported long-standing tensions with Defense Secretary Pete Hegseth. Driscoll, a former soldier who entered the role from the finance sector, was described as a 'change agent' focused on transformation. His departure follows Hegseth's broader purge of transformation-focused generals, according to sources cited by Defense One.
Why it matters: Driscoll's exit continues the pattern of Trump-administration Pentagon leadership churn, now reaching service-secretary level—if Hegseth is systematically removing officials pushing modernisation and uncrewed systems, European allies betting on U.S.-led transformation roadmaps (CCA, Replicator, JADC2) should assume those timelines are now political variables, not constants.
