John Kelly, Donald Trump s longest-service chief of staff, made dire warnings Tuesday about what could happen if his former boss wins back the White House, and confirmed disturbing comments the former president allegedly made about Adolf Hitler.

Kelly, a former Marine general who also served as Trumps homeland security secretary, spoke to both The Atlantic and The New York Times about his concerns, saying he was motivated to go on the record after Trump suggested hed use military force against his domestic political enemies.

Trump meets the definition of a fascist and would govern like a dictator, Kelly warned, telling the Times that Trump never accepted the fact that he wasnt the most powerful man in the world and by power, I mean an ability to do anything he wanted, anytime he wanted.
