When President Donald Trump chose Pete Hegseth for Defense secretary, incoming officials knew they’d need to surround the inexperienced Fox News host with accomplished staff who could handle the nation’s largest bureaucracy.

John Ullyot, a former Pentagon spokesperson under Hegseth and a White House official during Trump’s first term, wrote that “the last month has been a full-blown meltdown at the Pentagon — and it’s becoming a real problem for the administration”, in a stinging op-ed in Politico this week.

"Disgruntled former employees are peddling things to try to save their ass, and ultimately, that's not going to work," Hegseth said.
