Ruben Castro "made a big mistake" when he entered pleas last month to racketeering and conspiracy to sell cocaine.

Ruben Castro told a Los Angeles federal judge on Friday that he "made a big mistake" when he entered pleas last month to racketeering and conspiracy to sell cocaine.
The 48-year-old was supposed to be sentenced Friday and could have received 27 years in prison but that hearing was canceled. Arguments on his plea change will be heard in October. Prosecutors say he ran two branches of a drug-dealing Los Angeles street gang from behind bars while serving a life sentence in Colorado for a 1997 racketeering conviction.
