Pete Hegseth just can’t stop himself from using Signal. The defense secretary installed the encrypted-but-unclassified messaging app on a desktop computer in his Pentagon office to work around restrictions that prevent him from using personal devices to communicate with people outside headquarters.

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 appears increasingly likely 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.
