Jerry Oppenheimer is an American author who has written several unauthorized biographies of public figures including Hillary and Bill Clinton, Anna Wintour, Rock Hudson, Martha Stewart, Barbara Walters, Ethel Kennedy, Jerry Seinfeld and the Hilton family. During Clinton's 2000 Senate Election, Oppenheimer wrote the book State of a Union: Inside the Complex Marriage of Bill and Hillary Clinton. His claims were reported at the time, including the alleged incident when Hillary Clinton called her husband's campaign manager Paul Fray a "fucking Jew bastard" in 1974. Clinton denied these claims.
