Sigma Alpha Epsilon Fraternity Executive Director Blane Ayers pauses as he takes questions from reporters after a news conference, Wednesday, March 18, 2015, in Chicago. The college fraternity that has been under scrutiny since members of its University of Oklahoma chapter were caught on video engaging in a racist chant says it will require all of its members nationwide to go through diversity training. Ayers said he was disgusted by the video and apologized for the pain it caused and outlined steps meant to ensure it never happens again. (AP Photo/M. Spencer Green), APTOPIX
