If he gets the marriage annulled that means his kids are bastards. Or virgin births. Baby girl needs to write a tell-all book and get the bastard where it hurts. Then she won't need his money and can tell him where he can stick it. 
Made me wonder if there was prenup or some kind of settlement where she can't tell all or is cut off from the cash? Sounds like an O'Riley trick.
That is apparently how Rush and the rest of the right-wing family values hypocrites get away with all the shenanigans, including drugs, gambling, affairs, abuse, etc. They pay the women off, so like high-class hookers, they can't talk. And to some extent, the women know what they are getting into.
Nothing turns me off like proud ignorance plus self-centered arrogance, and that defines many of the spokesmen on the right. I'd sooner date an orangutan than a right-wing fool, no matter how rich. Great apes are more thoughtful, with better morals (less likely to abandon you and the kids while you are sick with cancer) and their conversation is on a higher plane. Many are also nicer looking than either Rush, Bill or Newt.
