Army Secretary Dan Driscoll has submitted his resignation to US President Donald Trump, three sources familiar with the matter told CNN on Monday, amid months of reported tensions with Secretary of War Pete Hegseth.
One of the sources said Driscoll's departure was not unexpected given the strained relationship between the two officials.
The White House praised Driscoll's tenure, highlighting his role in implementing Trump's defense agenda and overseeing the Army during a period of significant military activity.
“Secretary Driscoll has been highly effective in advancing President Trump’s agenda to Make America Strong Again at the Department of the Army by providing outstanding leadership during historic military operations, restoring an emphasis on readiness and lethality, assisting with negotiations between Russia and Ukraine, and more," White House spokesperson Anna Kelly said in a statement.
Driscoll, an Army veteran and longtime personal friend of Vice President JD Vance, is leaving the post six months into the war with Iran.
Earlier this year, Hegseth dismissed Army Chief of Staff Gen. Randy George along with two other generals. George and Driscoll had worked closely together, according to CNN.
The Wall Street Journal was first to report Driscoll's planned departure.
