Gen. Chris Donahue, the last U.S. service member to leave Afghanistan in the 2021 U.S. withdrawal, is retiring from his role as the commanding general of U.S. Army Europe and Africa, according to multiple reports.

Donohue submitted his resignation letter on Tuesday after reportedly clashing with Defense Secretary Pete Hegseth, according to CBS News. The four-star general becomes the latest high-ranking Pentagon official to head for the exits under Hegseth’s tenure, following the likes of Navy Secretary John Phelan, former Chairman of the Joint Chiefs of Staff Gen. Charles Q Brown, and former Army chief of staff Gen. Randy George.
