The racist chant by members of a University of Oklahoma fraternity caught on video on March 7 was part of the institutional culture at the chapter, an investigation by the Office of Student Affairs at Oklahoma State University released Friday revealed. The chant, which included at east one reference to lynching, was sung by fraternity members on a chartered bus on the way to the chapter’s annual Founder’s Day event in Oklahoma City. The university took swift action after the video of the chant emerged, expelling two of the students caught singing it.
