O’Brien explained what makes Trump so hard to joke about.

“You can’t parody something that already has that crazy, irregular shape,” he told host Kara Swisher. “It’s not possible. So I always thought that when Trump came along, what a lot of people have to revert to is: ‘Doesn’t he suck? I hate that guy. He’s an asshole.’ And those aren’t jokes.”

Going on to reference the 2021 Capitol riot, O’Brien continued: “I’m really going out on a limb here saying — that’s his greatest crime. I think he’s hurt political comedy by being so outlandish himself. I think the Jan. 6 thing is a blip compared to how much he’s hurt comedy.”

O’Brien said farewell to the grind in June 2021 as the host of TBS’ “Conan” ― and since then Trump has collected 91 criminal charges spread over 4 indictments while he attempts a baggage-ridden return to the White House.
