U.S. Army Secretary Driscoll tenders resignation, source says

"Driscoll brought up concerns with the administration surrounding Army transformation and readiness and Hegseth's blocking those efforts specifically by firing the generals who were responsible," the source said, referring to his efforts to modernize the Army.

The Army declined to comment on the news, which was first reported by the Wall Street Journal.

"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 spokeswoman Anna Kelly said in a statement.

The source said that Dave Fitzgerald, the deputy undersecretary of the Army who was focused on innovation within the Army, was also expected to resign. Fitzgerald did not immediately respond to a request for comment.
