A lawyer representing Penn State has asked a Pennsylvania judge to dismiss a lawsuit filed by the university’s former assistant football coach, Mike McQueary, asserting McQueary’s defamation and misrepresentation claims are not supported by Pennsylvania law while the entirety of his claims, including a whistleblower count, lacks specificity.

McQueary, who was a graduate assistant when he claims he saw the school’s former defensive coordinator, Jerry Sandusky, sexually assault a young boy, is better known for his role as one of the state’s key witnesses in the prosecutions against Sandusky and three high-ranking administrators also facing charges, than he is for his coaching experience at the school.
