Candidate Mitt Romney is on the defense over his tenure of Bain Capital. The Obama campaign says he was in charge of the firm during the years when it outsourced jobs. Another aspect of Romney's time at Bain Capital has been getting less attention though. During the 15 years he was there he managed to amass $102 million in his Individual Retirement Account. This is a considerable sum given the relatively small amounts the law permits a person to contribute to such an account on an annual basis. How did he do it? William Cohan, columnist for Bloomberg joins the show with some explanations.
