what exactly are these students saying, either themselves or through proxies? reporter: well, ashleigh, both are saying that they re sorry but choosing to do it in two different ways. first to parker rice, one of those 19-year-olds that was identified in the video as the leader of that unspeakably bigoted chant. part of that statement saying, i m deeply sorry for what i did saturday night. it was wrong and reckless. i made a horrible mistake by joining into the singing and encouraging others to do the same. on monday, i withdrew from the university and sadly at this moment, our family is not able to be in our home because of threatening calls as well as frightening talk on social media. i know everyone wants to know why or how this happened. i admit it likely was fueled by alcohol consumed at the house before the bus trip but that s not an excuse. yes, the song was taught to us but that too doesn t work as an explanation.
