NORMAN, Okla. — A racist chant by members of a University of Oklahoma fraternity that was caught on video led to outrage from the school’s president and the organization’s banishment from campus, but fallout from the incident appears far from over.

President David Boren said an investigation is under way to determine if some of the students could be expelled for violating Title VI of the Civil Rights Act. The video, which was posted online, shows several people on a bus participating in a chant that included a racial slur, referenced lynching and indicated black students would never be admitted to Sigma Alpha Epsilon.
