Rick Perry paid close to a half-million dollars in 2010 to settle a lawsuit against him. He was charged with laundering a $1 Million campaign contribution through the Republican Governor’s Association, using Mitt Romney as the conduit. Perry and the plaintiff signed a confidentiality agreement in exchange for Perry paying the money.
Maybe Perry doesn’t remember it, since it was so long ago. Maybe he can’t talk about it because of the non-disclosure agreement. Even though he said he didn’t do it, he paid out $427,000 to the plaintiff to settle it. Gee, that’s an awfully lot of money...he must have done something. < /sarc>
It looks like some people don’t like your source. Here’s another link with about 1,500 different sources to the story. Maybe there’s a source there that would be more acceptable.
