The White House has lost confidence in a Pentagon leak investigation that Pete Hegseth used to justify firing three top aides last month, after advisers were told that the aides had supposedly been outed by an illegal warrantless National Security Agency (NSA) wiretap.
In particular, one Trump adviser recently told Hegseth that he did not think Caldwell – or any of the fired aides – had leaked anything, and that he suspected the investigation had been used to get rid of aides involved in the infighting with his first chief of staff, Joe Kasper.
