by his word which has a lot of credibility issue, but by documents, checks, bank account statements, was able to put john edwards in the middle of the plot to keep the affair private. and in many ways today was an audio version of the politician. but andrew young helped john edwards in three key ways. one, he made clear that bunny mellon wanted nothing in return. two, he made sure mellon was told that these expenses were for personal matters, not political. and, three, andrew young said john edwards told him time and time again this was perfectly lawful. so andrew young may have made out the government's case, but he also helped john edwards. >> that's what i'm wondering about. it sounds like he made the case against the prosecution by saying this isn't a political expenditure. and this wasn't intended to be such by the one who gave the money, bunny mellon, the wealthy heiress.
