I'm not saying he's not a racist. I'm saying that he's a blowhard who thinks he runs the AD and he's pissed that he wasn't the decision maker (or, even consulted) on this hire. And he's doing what he does best - ranting and raving to anyone who will listen to him.
I get the blowhard bit, but I think his choices of words in demeaning CS that far is a bit of a red flag.
