The University of Oklahoma chapter of Sigma Alpha Epsilon was shut down Sunday by the national organization after a video surfaced that allegedly showed members of the fraternity chanting racist slurs and referencing lynching.

The video posted Sunday appears to show people on a bus clapping and chanting "there will never be a n***** SAE / You can hang them from a tree / But they'll never sign with me."

Oklahoma City's NBC-affiliated KFOR TV reported that the clip was filmed Saturday on what appears to be a bus allegedly headed to a date party for the fraternity founder's day. Members of sorority Delta Delta Delta were also invited to the party, and its national organization said Monday it was cooperating with the university.
