CNN — It's a subject Chelsea Clinton would clearly like to avoid, but the former first daughter again fielded a question on the Monica Lewinsky scandal Monday. Campaigning at North Carolina State, a student brought up the touchy- subject, saying the scandal was the public's business since the incident occurred when her father was President of the United States. The younger Clinton sharply disagreed she should discuss the matter. "It's none of your business," she said. "That is something that is personal to my family. I'm sure there are things that are personal to your family that you don't think are anyone else's business either." As the student left the event, the former first daughter also said she doesn't think people should "vote for or against my mother because of my father. The student later defended his comments to CNN affiliated WTVD, saying "I felt that it is our business because he was president at the time, and his first duty is to be chief citizen." The comments follow an incident at Butler University last week when a student asked whether the scandal had hurt her mother's reputation. Chelsea Clinton appeared taken aback by the question, saying, "Wow, you're the first person actually that's ever asked me that question in the, I don't know maybe, 70 college campuses I've now been to, and I do not think that is any of your business." The Butler student later said he was a supporter of Hillary Clinton's who was merely giving the former first daughter an opportunity to show how strong her mother is.
