He does remind me of the slime ball Senator potrayed in Godfather II in Nevada who had a change of heart about the Corleones after he was found with a dead hooker.
Funny you should mention that.
He had a movie cameo in the movie "Casino".
The Senator was played by the great character actor, G.D. Spradlin, Semper Paratus.
Who has made a very memorable career of playing slimy characters. An elegant, very highly polished Steve Buscemi.
Jack.
