TOPEKA, Kan. (AP) — A Washburn University fraternity has been suspended by its national leadership after sexually vulgar text messages between its members were discovered. The Topeka Capital-Journal reported Phi Delta Theta International said early Thursday it suspended the Washburn chapter as it investigates the messages. University spokesman Patrick Early says the Office of Student Life was interviewing fraternity members. Jessica Barraclough, the director of student activities and Greek life for Washburn, say the fraternity cannot host any events or participate in any university events during the suspension but members can still live at the house. Fraternity vice president Luke Warnken and president Jake Gregg told the Capital-Journal they wouldn't comment until they spoke to their attorney and heard from chapter advisers.
