Notice how often he refers to having voted for Hillary Clinton-- which is very easy to say, because no one is in the voting booth with him. He says that to piously claim that he is acting "contrary" to his own politics when he helps Trump.

In fact, he has been trying very hard to get Trump to notice him for 3 years now, trying to get hired, trying to get in the massive Trump orbit. And it's pretty funny that now he has finally made it, he's getting contrary AGAIN, or pretending to-- "I don't really want this. I'm not part of the team. I'm just giving a lecture like I did at Harvard."

I wonder how no-witness McConnell can justify letting this one person -- "NOT ON THE TEAM"- get up there and opine for an hour.

Also, we've heard Dershowitz say (not very persuasively), that "abuse of power" is not impeachable and not illegal for the president. (Though others say that's exactly what "high crimes" means-- that because you are president, you have the power to commit crimes others don't by abusing power.)

I don't think he's going to persuade many (and will annoy many) with his argument that the president can do anything he wants because he's the president.
