On the eve of the election, popular podcast host Joe Rogan officially endorsed Donald Trump, a move that Trump’s campaign team quickly highlighted as a significant boost in the campaign’s final hours.

Rogan on Monday released his latest podcast featuring a two-and-a-half-hour interview with billionaire X owner and top Trump surrogate Elon Musk. Rogan then posted on X: “The great and powerful @elonmusk. If it wasn’t for him we’d be f**ked. He makes what I think is the most compelling case for Trump you’ll hear, and I agree with him every step of the way.”

“For the record, yes, that’s an endorsement of Trump. Enjoy the podcast,” he added.

The endorsement comes just weeks after Rogan interviewed Trump on “The Joe Rogan Experience,” an interview that was months in the making for the Trump campaign and viewed widely by the former president’s advisers as the crowning achievement of their media strategy to target young men and low-propensity voters by having Trump appear on podcasts catering to the demographic.

While onstage in Pittsburgh, Pennsylvania, for his second-to-last rally, Trump quickly highlighted the endorsement after Rogan made it.

“It just came over the wires that Joe Rogan just endorsed me, is that great. Thank you, Joe. That’s so nice. And he doesn’t do that, he doesn’t do that stuff,” Trump said

Trump said, “And he tends to be a little bit more liberal than some of the people in this room.”

Rogan shared on X last week that he had turned down an interview request from Vice President Kamala Harris’ campaign.

“Also, for the record the Harris campaign has not passed on doing the podcast. They offered a date for Tuesday, but I would have had to travel to her and they only wanted to do an hour. I strongly feel the best way to do it is in the studio in Austin,” Rogan said. “My sincere wish is to just have a nice conversation and get to know her as a human being. I really hope we can make it happen.”

The Harris campaign chose not to comment on Rogan’s post.
