NORMAN, Okla. (CBSDFW.COM) – The Norman, Oklahoma chapter of Sigma Alpha Epsilon is now pursuing legal action after the University of Oklahoma shut down the fraternity earlier this week due to a racist video. Members of the group were caught on camera last weekend engaging in a racist chant.

But the group’s attorney said that the frat is outraged by OU’s president closing the fraternity and labeling the members as racists. They believe that the incident is being exploited, even after the two expelled members apologized for making racist remarks in the nine-second video.

Parker Rice and Levi Pettit, both from the Dallas area, were recorded singing a song that used derogatory language and referenced lynching. University president David Boren ordered the fraternity house shuttered, and Rice and Pettit were both expelled after being identified as the chant’s ringleaders. Other fraternity members are under investigation.

The group’s lawyer plans to review all of the information on Friday and make a decision on how to move forward in this case.

Alumni from the Norman fraternity chapter released a statement on Wednesday, saying that the chant began “three to four years ago and was not immediately and totally stopped. It should have been.” Two former members of the chapter have also issued apologies for their role in the racist chant.
