Army Secretary Dan Driscoll has submitted his resignation to President Donald Trump, officials said Monday, paving the way for him to depart the administration in coming days after repeated clashes with Defense Secretary Pete Hegseth.
Driscoll has served as Army secretary since February 2025, overseeing efforts to make the service more modern and nimble and taking a leading role in the Trump administration’s efforts to defend against the proliferation of cheap, deadly drones.
