The MSM has locked Trump out of any major media since 2015, unless it was forced to, when he was President.
I doubt this has been by Trumps choice. He strikes me as a fellow who will talk to anyone, anywhere, at any time.
If Joe Rogan agreed to have him on, I’d think he’d go.
Trump is very practical minded and being on a three hour show that is dedicated to letting the chips fall unedited would be something he’d be interested in.
Trump is willing to take the battle to the enemy and getting upward 100 million people to hear him, who may not have heard his message before, would be something he would do I think.
