Defense Secretary Pete Hegseth said the Pentagon will welcome Elon Musk’s Department of Government Efficiency to address redundancies and waste in the Department of Defense—a comment that comes as controversy surrounds Musk’s powerful agency and questions of what it can and cannot do in different departments.
