Pennsylvania's Republican Governor Tom Corbett equated same-sex relationships to incest during an interview that aired on television Friday. In a response to a court filing in which his administration's lawyers compared gay and lesbian couples to children, Corbett said, "It was an inappropriate analogy, you know.

He later apologized, adding that he wanted to give examples of the types of people barred from obtaining a marriage license in the state.
