Two men who say Michael Jackson sexually abused them as children are opening up about their experiences with the pop icon. Wade Robson and James Safechuck are featured in an explosive new documentary premiering Sunday on HBO. Both men also sued the Jackson estate, but their lawsuits were dismissed because of the statute of limitations. They are appealing. Jackson always denied any inappropriate behavior with children. Robson and Safechuck tell "CBS This Morning" co-host Gayle King about their relationships with Jackson, including very graphic allegations of abuse that some viewers may find disturbing.
