Two weeks after a video surfaced showing some members of the University of Oklahoma’s Sigma Alpha Epsilon fraternity singing racists chants, the organization says it’s taking steps to make sure nothing like that ever happens again. The video was recorded on a bus after a social event. On the tape there are references to lynchings along with vows never to allow black people in the fraternity. SAE’s national headquarters is based in Evanston. Today the organization held a news conference to lay out plans to prevent future incidents. WBEZ’s Yolanda Perdomo was there and joins the conversation.
