The racist chant sung by University of Oklahoma fraternity members on a bus ride earlier this month originated at a Sigma Alpha Epsilon national leadership cruise four years ago and then was brought back to Norman where it was taught to pledges and others, President David Boren said today when releasing what he called a comprehensive investigation into the incident.

Boren, in a news conference outside of Evans Hall, said 24 or 25 students had been discplined because of the March 7th incident, the punishments range from the expulsion of two students, Dallas natives Levi Pettit, 20, and Parker Rice, 19, and community service and sensitivity training for others on the bus as well sa for the fraternity’s seven officers. There will be no further expulsions from this incident, he said.

Several young women who were on the bus as dates of the members, including several sorority members, will not be disciplined. Boren said none particpated. Boren also said after that it was two different sorority girls that released the videos to the public and that the two should be applauded for doing so.

Before the news conference, Boren met with members of the universities Black Student Association, panhellinic council, members of the football team including Bob Stoops and linebacker Eric Striker and seven officers from the now defunct SAE chapter to share their hopes for how this event will change OU. The members from SAE apologized at the meeting, and Boren said their apology was accepted.
