Jimmy Kimmel says any "reasonable person ... should have Trump derangement syndrome," ripping the former president as "dangerous." "I laugh when people say, 'Oh, you’ve got Trump derangement syndrome.' If you're a reasonable person, you should have Trump derangement syndrome," Kimmel told MSNBC's "Morning Joe" anchor Joe Scarborough in an interview that aired Wednesday. "I think he has derangement syndrome about us, too," said the "Jimmy Kimmel Live!" host — who is engaged in a regular war of words with the ex-commander in chief. Kimmel regularly skewers former President Trump on his show, while the 45th president has slammed the TV personality as “dumb” and called his ratings “terrible.” "The fact of the matter is, this is a dangerous person. This is a stupid person. And that’s a bad combination," Kimmel said. Trump, who was convicted on 34 felony counts in New York earlier this year related to a hush money scheme, is "literally running for his freedom," Kimmel claimed. "I keep forgetting it and I have to keep reminding myself — is he’s not just running for president, he’s running to stay out of prison. And that’s a pretty powerful thing," he told Scarborough. The former president, who has repeatedly dismissed his multiple criminal and civil court cases as election interference, said in a Thursday interview that he would immediately oust the special counsel investigating him if he returns to the White House. "It’s so easy. I would fire him within two seconds," he hold radio host Hugh Hewitt. Earlier this month, Trump suggested in social media posts that some TV networks should be investigated over what he described as bias against him. Asked about his level of concern that what he does on his late-night show "may have to change" if Trump wins next month's election, Kimmel replied, "I’m concerned, certainly. I think that it would be so un-American if he were to come after people who are speaking out against him." Kimmel, 56, said he hasn't come to terms with Vice President Harris potentially not winning the election. "I was telling my wife, I don’t feel like I’m mentally prepared for the possibility of a loss," he said. "I have to get there where I’m ready for either scenario or for no scenario, which is — might be the case for several days, who knows?" Kimmel said.  "I have to also kind of think through what I might say the next day," he added.  "Most of my shows aren't important — that one seems a little bit more important than others, because I do have a lot of people kind of asking me what I think and going along with what I think. And it's a big responsibility," Kimmel said.
