The truth no doubt is, so is a lot of other stuff. I have serious doubts about some of this; the explanations I've come upon elsewhere includes some direct contradictions. According to one succesful businessman I once worked for, Ron and Nicole were murdered by the same Arkansas hit squad who took out Vince Foster, and the motive was to create a big news story which would deflect media attention from Hillary's problems.
As for the assertions I linked, I think these people are behind them.
