Exclusive: The White House is looking to replace Pete Hegseth as defense secretary

The White House has begun the process of looking for a new secretary of defense, according to a U.S. official who was not authorized to speak publicly.

This comes as Defense Secretary Pete Hegseth continues to find himself mired in controversy. NPR has also confirmed with the same official that Hegseth shared details ahead of last month's Yemen strikes with his wife and brother in a Signal chat on his personal phone, minutes after being updated by a senior U.S. military official. The news of the second Signal group chat about the mission was first reported by The New York Times.

In March, Hegseth shared details about action against Houthi targets in Yemen in a Signal chat with top White House officials that accidentally included a journalist.
