If the guest was who I think it was, he had a discussion on a talk show explaining Trump’s manner of speaking and it was fascinating, like how he uses the same words all the time because he doesn't know that many others. Lol. John Wortner, or something like that. A professor I believe. Very knowledgeable in linguistics. The race topic was a little harder to follow for me. And he looked so angry all thru it, but a big smile at the end, like he really enjoed his time there.
