On CNN this week, former Indiana Rep. Dan Burton told Anderson Cooper that he believes that mercury-based vaccine preservative caused his grandson's autism.

I'm for vaccinations, but we need to get the mercury out of all of them," Burton told CNN's Anderson Cooper. "Well, are you against breastfeeding?" Cooper asked? Burton replied that he is not. "OK, but you are aware that methylmercury is actually in breast milk that's given to children?" Cooper asked "If the child is only breastfed, they get more methylmercury than they would ever have gotten in any of the vaccines. You're aware of that, right?" Burton replied that he is not an expert on breastfeeding.

When Cooper pointed out that methylmercury has been either removed or greatly reduced in vaccines, Burton said, "You're a very bright young man, but I don't know where you get your information."

You may remember Dan Burton as the US Congressman who called Clinton a "scumbag," and said of Clinton, "No one, regardless of what party they serve, no one, regardless of what branch of government they serve, should be allowed to get away with these alleged sexual improprieties…" Burton himself finally admitted to fathering a child out of wedlock in 1983, something he indignantly denied for years until an expose revealed that he was a liar.
