Another interesting exchange between Michael and Hagen which gives us a bit more insight into who Turnbull was and how he was involved with the Corleones, as well as providing a bit of information about Geary.

-------------------------------------------

HAGEN: I've cleared it through the Senator's chief aide, a man named Turnbull. Turnbull's a heavy gambler, and into us for over a hundred grand, so I figure his information is reliable.


HAGEN: The Senator can be set up; but he thinks of himself as a clean politician. So it's got to be on terms he can live with: campaign contribution, donation to a charitable cause that he controls, things like that. If he gets even the inkling that you think you're buying him, he'll freeze up. Nevada's a funny state, they like things both ways here... All right. Turnbull says the Senator will be here at two-thirty, and he's been
primed. He knows you'll want to meet with him alone, and he knows it's about the Tropicana's license. At any rate, he expects to be introduced around to some of the influential people here today, and generally treated as an ordinary guest. Just go light on him, Mikey, sometimes the biggest crooks don't like to think of themselves as crooks...
