Until a student is expelled from campus for a supposedly racist and/or threatening tweet. I say supposedly because I can't find what the tweet says, but if there was no threat made I don't see grounds for expulsion. The first amendment guarantees your right to be an utter revolting shit if you want to be one. Is KSU now going to have twitter police monitoring every student's tweets? I just wish I knew what the tweet said. If it was just along the lines of a certain race or group is a bunch of subhuman garbage and I wish they weren't here then that is despicable but I see no grounds for expulsion. If the student added "and I wish they were all dead and I'm going to start making that happen" then you possibly have an entirely different ballgame as you have entered threat territory.
