Resignation comes after months of turmoil at Pentagon, from leaked investigation to ousting of senior officials

The army secretary, Dan Driscoll, has handed his resignation to Donald Trump, the White House said on Monday, becoming the latest high-profile figure to depart the defense department.

The army official, who is second in line to the defense secretary, Pete Hegseth, had reportedly been eyeing an exit from the Pentagon amid apparent friction with the secretary.

Letter from chair of joint chiefs of staff addresses concerns over Trump officials using military to interfere with vote

The highest‑ranking US military officer says there are no plans to deploy troops to polling places during the November midterm elections – responding to Senator Elissa Slotkin’s request for information amid concerns about whether the Trump administration might send service members to election sites.

In a letter obtained by the Guardian, first reported by the Associated Press, Gen Dan Caine, chair of the joint chiefs of staff, told Slotkin “the Joint Force has no plans to send Federal military personnel or Federalized members of the National Guard to polling places during the 2026 elections”. He added that there were also “no plans to use such personnel to seize ballots, voting machines, or other election‑related material”.

Response seeks to discredit Washington Post story that four generals and admirals advised against prolonging Iran war

Pete Hegseth regularly receives formal objections from senior commanders and proceeds anyway, the Pentagon’s top spokesman has said, as he tried to discredit a Washington Post report that four generals and admirals had advised against prolonging the war in Iran.

“Of course, we demand candid military advice,” Sean Parnell wrote on X, formerly Twitter. “Non-concurs are standard. The Secretary sees them constantly. That’s how you run a real military.”
