According to CNN, Driscoll “spoke to the president about the current state of the Army and submitted his resignation.”

White House spokesperson Anna Kelly said, “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.”
