USD Professor Sues to Block Firing Over Charlie Kirk Social Media Posts

A University of South Dakota art professor, Michael Hook, filed a lawsuit on September 23, 2025, to prevent his termination over social media posts about the September 10 killing of conservative commentator Charlie Kirk. Hook, a tenured professor, claims his administrative leave and impending firing violate his free speech rights. His initial post used profanity and questioned media coverage disparities, but he later apologized. South Dakota leaders, including Gov. Larry Rhoden, supported his termination. The lawsuit, filed in federal court, argues the Board of Regents’ actions are unconstitutional and seeks to end Hook’s leave and cancel a September 29 termination conference. The Board of Regents declined to comment on the litigation.
