Elon Musk has abruptly withdrawn from a deal to exclusively host journalist Don Lemon’s new talk show on X (formerly Twitter), shortly after he interviewed the billionaire last Friday, the former CNN anchor has said.

In a statement on Wednesday, Lemon explained that the deal was part of X’s public commitment to “amplifying more diverse voices on their platform” and that Musk had encouraged him to join X with a new talk show and promised to support the project.

However, several hours after filming an interview with Musk on Friday, which Lemon described as a “good conversation,” the billionaire allegedly messaged the former host, informing him that the partnership contract with the Don Lemon Show had been terminated without explaining the reasons.

“His commitment to a global town square where all questions can be asked and all ideas can be shared seems not to include questions of him from people like me,” Lemon suggested, adding that there were no restrictions on the interview that Musk had agreed to, and insisted that his questions were “respectful and wide ranging.”
