I think Shmuley back-stabbed him, as we learn MJ and him parted ways. I think like the poster above that Shmuley 'may' (or not at all) have helped edit this speech, but certainly not have written it for MJ as he said he did. Everywhere I hear MJ speak, and now with reading Back, Front and TS, it all speaks one message---that MJ was/is an extremely articulate well-informed and funny as all get-out speaker.
Shmuley was probably jealous of his ability, and he as a white educated Jew couldn't do as well.
