Key is a law student who had a Facebook page with a picture of Robertson looking like he was giving the finger. Robertson is the president of Key's law school, Regent University, and Key got a 2 year suspension. He's now suing in federal court:
Key’s suit also alleges the school defamed him and violated his right to free expression, required under requirements of the Higher Education Act for schools that receive federal funds. It also claims he was “fraudulently induced” to enroll at the school on the basis of Regent’s assurances that it allowed religious liberty and free speech.
