He was on after the revelations about the cuck article became mainstream. I'm sure the interview was set up before that, but this is someone to whom Tim had given airtime repeatedly, and during that livestream, when members of his audience were asking him to ask Jack about that article, he repeatedly attacked them as being hungry for "drama," etc. He let Murphy carry on with his act, even after he'd been outed. His job as a journalist is to get to the truth, which is something he repeatedly fails to do: this is just one example. He would prefer to keep giving a known fraudster airtime and lend him the perception of legitimacy that being on Timcast provides, rather than actually ask him tough questions.
