As much as I dislike Huck, I suggest folks read the comments on that article. There seems to be some dispute on whether he received the payments while he was sitting as governor, as well as dispute on the business the company was/is in.
It really does not matter. He took money from an outfit that traffics in human embryos. That is completely contrary to his whole image as a prolife purist. People in Iowa need to know who they are voting for.
