I believe this is referring to the crazy haired guy he always has on who wrote the book about the covid hoax. He said something to the effect that republicans cannot fight for donald trump because it is likely that Biden will be getting in and that instead of fighting for trump we should be fighting to keep the mask mandates and lockdowns from happening. In Tucker's defense, he did say that he thinks we should fight all of it. But I would have liked to hear him defend potus a little more, I'm pretty sure the brass at Fox tightened his leash up a bit. I'm still a fan, I think he knows Fox will be his biggest audience so he puts up with a little muzzling now and then.
