University of Oklahoma President David Boren has expelled two students accused of leading a racist chant at a fraternity event last week. 

The incident was captured on video and has been circulating the Internet, sparking outrage both within the university and elsewhere. 
The school also announced it would sever all ties with its local chapter of Sigma Alpha Epsilon, and ordered that the house be evacuated immediately. 

Parker Rice, one of the students involved in the scandal, has issued a public apology: "I am deeply sorry for what I did Saturday night," he wrote. "It was wrong and reckless. I made a horrible mistake by joining into the singing and encouraging others to do the same." 

He added that since the story surfaced, he and his family have had to temporarily vacate their home due to threats. 

The family of another student, Levi Pettit, also apologized for their son's involvement. "He made a horrible mistake and we will live with the consequences forever," they said.
