Joe Kasper, who served as the chief of staff under Defense Secretary Pete Hegseth, has announced his departure from his current role but will continue to serve as a Special Government Employee. This development comes in the midst of a series of exits from senior Pentagon positions, which have been linked to a leak investigation and allegations of slander. Pete Hegseth himself is under scrutiny for allegedly discussing Yemen strikes through the encrypted messaging app Signal. Despite these controversies, the White House has reiterated its support for Hegseth. The situation underscores the ongoing challenges and controversies within the defense sector in the current political climate.
