Pete Hegseth has been accused of leaving himself open to hacking by America’s enemies by using his personal phone number in a top security Signal chat that was easily accessible on numerous internet sites and apps.

Pete Hegseth was barely able to get confirmed as Donald Trump’s Defense secretary, and following a series of scandals — including the revelation that he shared U.S. war plans in a second Signal group chat last month — it’s entirely possible that he will be the first member of Trump’s Cabinet to either resign or be forced out not even 100 days into Trump’s second term.

Joe Kasper, Hegseth's former chief of staff, is the latest Department of Defense official rumored to be leaving.
