The Arizona State University chapter was expelled by the university after photos surfaced of a racially themed "MLK Black Party" on Martin Luther King Jr. Day holiday weekend, although it later surfaced that the event was not planned by members of the fraternity. The party included guests wearing basketball jerseys, flashing gang signs, and drinking from watermelon cups. The school's decision to ban the chapter was also because the TKE chapter had recently been placed on probation after two members of the fraternity pleaded guilty to the aggravated assault of a student from another fraternity. The national fraternity issued an apology and condemned the event but insisted that the party was "without malice or forethought", that there were fewer than 30 men and women at the event which didn't meet Arizona State IFC guidelines for an official fraternity function, and that the ASU chapter was one of the most "multi-cultural social fraternities" at the university.
