The president of a Dallas prep school says it appears a graduate is one of the University of Oklahoma students leading a racist chant captured on video during a fraternity event.

A letter posted on the Jesuit Dallas website by school president Mike Earsing does not identify the student. But Earsing says he is appalled by the actions in the video and extremely hurt by the pain it has caused the community. He says everyone at Jesuit Dallas is committed to a culture of justice and equality.

University of Oklahoma President David Boren announced Tuesday that two students he did not identify have been expelled over the video, which shows several people on a bus participating in a chant that included a racial slur. It's not clear if the Jesuit Dallas graduate was one of the suspended students.
