The president of the University of Oklahoma is chastising fraternity members after a video was posted online showing some participating in a racist chant.

University President David Boren joined students at a rally Monday morning on the Norman campus, calling those who took part in the chant "disgraceful." Boren said, "real Sooners are not bigots, real Sooners are not racist."

Sigma Alpha Epsilon said Sunday night that an investigation confirmed the contents of a video showing multiple people chanting a racial slur and indicating blacks would never be admitted to the fraternity. The chant also references lynching.

The national fraternity released a statement saying it was "embarrassed" by the "unacceptable and racist" behavior. It says it's closing the local chapter.

The video was first posted by a black student group.
