Oh, I agree that Ayers wrote the book, TRP. But anything out of his mouth is likely to be a straight-faced lie, so what sort of witness is he in this case? There’s always the suspicion that he’s punking us all, sort of like a verbal version of a Kenyan BC. The irony is that this is probably one of the (rare) times he’s telling the truth, but he can’t be harmed much by it, since it’s coming from his own lying mouth.
But he raised the issue, and someone should call him on it.
I’m sure the WH has contacted him for an explanation.
If he was joking, then ask him, “why would you joke about that?”
