Many years ago, I did extensive studying of this issue. I don't remember Hillary's involvement but I remember Bill knew and looked the other way. I believe those involved were his supporters.
Sorry, I missed your note earlier today.
We documented a lot of it here in Free Republic. Bill did much more than look the other way. Throughout all six of his gubernatorial terms he actively lobbied for the blood plasma program, defended it, revived it when the feds shot it down. We had reason to believe that the Clintons were paid off for these favors big-time -- in Democrat-controlled Arkansas of that era, every important deal was approved by, and paid off to, the governor's office. That was one-party rule at work. This was a multimillion-dollar scam, so the payoffs must have been huge. The doctor who ran the tainted blood scheme admitted to making $500,000 a year from it, and heaven knows how much more he managed to conceal. Bill always specialized in the politics, Hill was always the greedy one, and she handled the money.
