U.S. Navy Secretary John Phelan leaves post

U.S. Navy Secretary John Phelan left his post effective immediately, the Pentagon said, with Under Secretary Hung Cao set to serve as acting Navy secretary.

The Pentagon did not give a reason for Phelan’s departure. In a brief statement, Pentagon spokesman Sean Parnell thanked him for his service and wished him well in his future endeavors.

Phelan’s exit marks the latest senior-level shake-up at the Pentagon under Defense Secretary Pete Hegseth. Reuters reported, citing a source, that Phelan was fired.
