Former President Donald Trump repeatedly praised Adolf Hitler and other dictators while in office, ex-White House Chief of Staff John Kelly says in a new interview in which he calls the GOP presidential candidate an authoritarian who fits the “general definition of a fascist.” Kelly went on the record with an audiotaped recollection of Trump’s remarks that the Nazi dictator did some positive things for Germany, the New York Times reported late Tuesday. “He commented more than once that, ‘You know, Hitler did some good things, too,’” Kelly said of Trump, who “certainly” aimed to rule the U.S. as a strongman like the dictators he admires. “Certainly the former president is in the far-right area, he’s certainly an authoritarian, admires people who are dictators — he has said that,” Kelly said. “So he certainly falls into the general definition of fascist, for sure.” The former Marine four-star general said he tried to explain that Hitler was a blood-thirsty antisemitic dictator who killed millions of innocents, but the protests fell on deaf ears.   Former President Donald Trump.

In the new interview, he also says Trump praised so-called “German generals” to highlight his own complaints that the U.S. military is not permitted to take political sides. “Surely you can’t mean Hitler’s generals?” Kelly said he asked the former president. Trump responded: “Yeah, yeah, Hitler’s generals.” Trump’s campaign refuted Kelly’s account, saying the ex-top aide is lying and “beclowned himself.” “He failed to serve his president well while working as chief of staff and currently suffers from a debilitating case of Trump derangement syndrome,” spokesperson Steven Cheung said in a statement. Vice President Kamala Harris hit out at Trump on Wednesday, calling the account of Kelly a “window into who Donald Trump really is.” “It is deeply troubling and incredibly dangerous that Trump would invoke the name of Adolf Hitler,” Harris said in front of her residence at the Naval Observatory in Washington. “We know what Donald Trump wants: unchecked power.” Adolf Hitler (Hulton Archive/Getty Images) Kelly had already said he considers Trump to be a danger to democracy and that he won’t vote for him, but he has declined to endorse Democratic presidential nominee Kamala Harris. The majority of Trump’s former cabinet members have said they won’t vote to return him to the Oval Office. Ex-Vice President Mike Pence says he cannot support Trump due to the former president’s effort to overturn their loss in the 2020 election. That scheme culminated with the violent Jan. 6 attack on the Capitol, during which Trump supporters built a makeshift gallows with a noose and chanted “Hang Mike Pence.”
