After it was revealed that President-elect Donald Trump would sit for an interview with hugely popular podcast host Joe Rogan just two weeks before the election, word leaked that Democratic nominee Vice President Kamala Harris' campaign was negotiating with Rogan for a similar appearance on his show.

The Harris-Rogan interview never happened though, and Rogan has now suggested it is because her campaign made a series of demands, including placing some issues off-limits, such as her evolving stance on marijuana legalization, Fox News reported.

Rogan indicated that he was amenable to accommodating the demands from Harris to make the interview happen but the plans still failed to materialize, and now one of the VP's top advisers has said it was because of the campaign's fear of "backlash" from the progressive left.

Harris didn't want to talk about marijuana legalization

During Rogan's podcast on Tuesday, he revisited the fruitless negotiations to land an interview with VP Harris before the election and said, "They had, I don’t know how many conversations with my folks, but multiple conversations giving different dates, different times, different this, different that, and we knew that she was going to be in Texas, so I said, 'open invitation.'"

"I think they had requirements on things that she didn't want to talk about, she didn't want to talk about marijuana legalization, which I thought was hilarious," he continued.

Rogan's guest, comedian Adrienne Iapalucci, inquired why that subject might be off-limits for discussion, and Rogan replied, "Because of her prosecuting record. She put a lot of people in jail for weed."

Indeed, according to USA Today, while Harris now claims to fully support marijuana legalization at the local, state, and federal levels, that certainly wasn't the case when she was a prosecutor in California.

In fact, first as the San Francisco district attorney and then later as California's attorney general, Harris oversaw the prosecution and incarceration of nearly 4,000 individuals for marijuana-related offenses and openly campaigned against efforts to decriminalize or legalize the drug during that time.

Campaign made other demands; also feared "backlash" from staff, supporters

Fox News reported that Rogan also revealed a few other demands made by the Harris campaign during Tuesday's episode, including that an interview be limited to just one hour -- his show typically runs around three hours -- and that he travels to meet her in Washington D.C. instead of her coming to his studio in Austin, Texas.

Rogan, who made it clear on multiple occasions before the election that he wanted to have a conversation with Harris, also addressed the demands made by her campaign during Friday's episode and said, "There were a few restrictions of things they didn’t want to talk about, but I said, 'I don’t give a f--k, get her in here.' Like, whatever you want to talk about."

Yet, despite Rogan's apparent flexibility, an agreement was never reached, and the real reason may have been revealed by one of the campaign's top advisers, Jennifer Palmieri, according to the Independent.

"There was a backlash with some of our progressive staff that didn’t want her to be on it, and how there would be a backlash" with the candidate's far-left progressive base of support, Palmieri told a conference on Wednesday, and added that a "very weird dynamic" developed between the campaign and the show after news of the negotiations for an interview were leaked.

Both Trump and Vance appeared on Rogan's show

Meanwhile, as the negotiations between Rogan's team and the Harris campaign broke down, there was no similar occurrence with the Trump-Vance campaign, as the popular podcaster landed major interviews with both members of the Republican ticket.

Arguably, Rogan's two highly watched three-hour-plus episodes featuring interviews with Donald Trump and Sen. JD Vance (R-OH) -- followed by Rogan's last-minute endorsement of Trump over Harris -- helped bolster turnout in support of the former president among the podcaster's massive audience and contributed to his victory on Election Day.
