But he may play them for his publisher to confirm. That's what Wolfe did. Also Omarosa might have relevant tapes. That would be interesting.

His reputation exceeds those accusing him. Unless he has permission I wouldn't count on it.

They are likely interviews with staffers, etc. which can be brushed off as here say and bad blood. There are probably no tapes of the principals bashing Trump and he will likely not want to blow the cover of those who did speak.

Revealing sources is a no-no, but the poster above who said WOLFE's publisher reviewed his sounds good.

Woodward didn't get where he is by revealing his sources.

And now some are denying they said what's in the book. If he has those statements on tape, that's not revealing any source that he hasn't already quoted.

In interview that he didn't frame it as so and so said this. He put it as, these people were in the room and here's what was said. And he said--I'm not going to reveal my sources on this.

Guess we'll have to read the book.
