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.
