Pete Hegseth wanted to make waves at the Pentagon. But less than 90 days since being sworn in as U.S. defense secretary, he appears put off balance by the very turbulence he himself created.

An ex-Fox News host, Hegseth on Monday accused his former trusted advisers of turning against him following revelations that he texted sensitive U.S. military strike plans from his personal phone to his wife, brother, attorney and others.

"What a big surprise that a few leakers get fired and a bunch of hit pieces come out," Hegseth said on the White House lawn, his children standing behind him, for an Easter celebration.
