A federal investigation has revealed taped conversations that may confirm Reggie Bush took cash and gifts while at USC.
According to an investigation by Yahoo.com, nearly $280,000 in cash, rent and gifts was allegedly given to Bush and his family. If the taped conversations ever become public, USC could face stiff penalties from the NCAA. The Houston Texans reportedly passed on Bush in part because they felt he was lying about his involvement with this scandal.
