Pentagon chief of staff Joe Kasper to step down amid Signal war chat controversy, says US official

Joe Kasper, chief of staff under Defense Secretary Pete Hegseth, is departing his role but will remain as a Special Government Employee. This follows several other departures from senior Pentagon positions amidst a leak investigation and accusations of slander. Hegseth is also facing scrutiny for reportedly discussing Yemen strikes via Signal, though the White House has expressed its support.
