Trump faces Democratic Vice-President Kamala Harris in the US election in what polls show to be a tight race.
Harrishas received multiple celebrity endorsements.
“For the record, yes, that’s an endorsement of Trump,” Rogan said on X while posting a clip of his interview with billionaire Elon Musk, who has also endorsed Trump.
Rogan said in his post that Musk made the “most compelling case for Trump”.
Trump’s recent interview with Rogan lasted about three hours and was released on YouTube and Spotify in late October.
The two discussed a range of topics and the interview got over 45 million views on YouTube.
The former President criticised Rogan in August on Truth Social, his social media platform, after the podcaster praised then-independent candidate Robert Kennedy Jr. Kennedy has since pulled out of the race and endorsed Trump.
Harris’s team had been in touch with Rogan’s program about a possible appearance but her campaign said in late October she would not appear on his podcast.
Rogan joins a list of celebrities such as Musk and wrestler Hulk Hogan to have endorsed Trump.
Harris has a much bigger list of celebrity endorsements, ranging from basketball superstar Lebron James and actor Meryl Streep to comedian Chris Rock and former talk show host Oprah Winfrey.
