The son of former New York City Mayor Rudy Giuliani is suing Duke University, claiming his golf coach manufactured accusations against him to justify kicking him off the team to whittle the squad.

Andrew Giuliani, a 22-year-old who will be a senior this fall, contends he had dreams of becoming a professional golfer and was dismissed without cause from the golf team in February without a chance to defend himself. He said in a statement Thursday that he sued “to make sure this doesn’t happen to anyone else at Duke.”
