Following President Donald J. Trump’s agreement to go on the Joe Rogan podcast, his riva, Vice President Kamala Harris is refusing to follow suit, according to her campaign spokesman Ian Sams. On Thursday, Sams stated, “We discussed the possibility with Rogan’s team, but due to current campaign scheduling, it won’t be feasible at this time.”

Reports earlier this month indicated that Harris’s campaign had been communicating with Rogan. His podcast, which had 14.5 million followers on Spotify and an even larger number of YouTube subscribers in March, appeals to a wide audience, including many young men—a demographic the Democratic nominee is struggling to appeal to.

President Trump is set to record an episode of The Joe Rogan Experience on Friday at Rogan’s Austin, Texas studio on Friday.

Rogan, who previously argued that foreign-born Americans should be able to run for the presidency and once advocated for a Star Trek-like communist utopia, has been critical of President Trump in the past, suggesting the president may be a “sociopath.” However, he admitted the former president was more mentally capable than Joe Biden, and he recently said that “Trump raising his fist and saying ‘fight!’ after getting shot is one of the most American f***ing things of all time.”

President Trump has been on several major podcasts in recent weeks, including the Theo Von podcast and the Lex Fridman podcast.

Kamala Harris, meanwhile, has been on far fewer podcasts. On one, the sexually explicit Call Her Daddy, she justified not having any of her own children by saying she did not want to be “humble.”
