(Pullman, WA) -- All fraternity and sorority social events are being banned on the Washington State University campus through the remainder of the fall semester. The "Spokesman-Review" reports the announcement came yesterday from the elected student-run councils that oversee Greek life on the Pullman campus. The councils cite a rising concern over the number of alcohol- and drug-related incidents at events in the Greek community. Members are being required to work with the university on creating a comprehensive plan to foster awareness surrounding sexual assault, abuse of alcohol and drugs, and the injuries that can result.
