Joe Rogan appeared to question President Donald Trump’s UFC event at the White House on June 14, which happens to be Trump’s 80th birthday. (Watch the video below.)

Rogan, the popular podcaster and UFC commentator, scoffed at details provided by Trump recently.

“So, Jamie, what were you just saying?” Rogan began by addressing producer Jamie Vernon on “The Joe Rogan Experience” on Tuesday. “I stopped you because it sounded so crazy.”

Vernon replied offscreen that, according to Trump, the event would host “eight to nine” title fights, which perked up the skeptic in Rogan.

“First of all, there’s only eight weight classes, so how’s there gonna be nine title fights?” Rogan said, laughing. “‘That’s kind of a crazy thing.’”
