Zeta Beta Tau involved in several controversies at multiple universities.

From Wikipedia-

On February 11, 1988, the Judicial Inquiry Office charged the Zeta Beta Tau fraternity with violating 7 Pennsylvania statutes and University of Pennsylvania guidelines including sexual and racial harassment during a fraternity rush event on October 1, 1987. The fraternity was accused of hiring two African American women to perform before an audience of 100-200 men during the alleged ZBT rush event. While the two women were undressing, the crowd yelled "Where did you get them niggers?" and other racist remarks. While the two women were performing they were being touched by the ZBT Officers and other participants at this event. The lewd acts continued with sexual penetration and oral sex

A freshman who was at the rush party earlier in the evening, eventually rattled out the fraternity. He would later gain fame involving another college controversy at The Evergreen State College. Bret Weinstein.
