A former University of Oklahoma fraternity member who was shown in a video chanting a racial slur has issued an apology, as have the parents of a second student.

In a statement Tuesday, former OU student Parker Rice called the incident caught on video "a horrible mistake" and "a devastating lesson" for which he is "seeking guidance on how I can learn from this and make sure it never happens again."

The statement was emailed to The Associated Press by Rice's father.

Meanwhile, the parents of another student seen on the video, Levi Pettit, released a statement that said, "he made a horrible mistake, and will live with the consequences forever."

The apologies came after OU President David Boren expelled two students who appeared to be leading the chant.
