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

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 defense secretary Pete Hegseth, had reportedly been eyeing an exit from the Pentagon amid apparent friction with the secretary.

The resignation comes after months of turmoil at the defense department, which has seen numerous incidents, from leak investigations and budget issues to the ousting of several senior officials including the army chief of staff Randy George in April. In June, the army’s commander of its forces in Europe and Africa, Gen Christopher Donahue, unexpectedly stepped down.
