NORMAN, Okla. (AP) — A racist chant by several 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 appears far from over.

President David Boren said an investigation is underway to determine whether some of the students from OU’s chapter of Sigma Alpha Epsilon could be expelled for violating Title VI of the Civil Rights Act, which prohibits racial discrimination.

The incident also had a profound effect on the Norman campus. Students organized a pre-dawn rally, and the football team decided to protest rather than practice.

The video shows several people on a bus participating in a chant that included a racial slur, referenced lynching and indicated that black students would never be allowed to join the fraternity.
