The world will be shocked—shocked!—to hear that Bill Clinton may not be the first president to have had an affair in the White House. Mimi Alford’s new book, Once Upon a Secret: My Affair With President John F. Kennedy and Its Aftermath, will be published on Wednesday. Alford was a 19-year-old intern and a virgin when the president invited her for drinks, she says. She claims they began the affair when the first lady was away, sleeping together in Jackie’s bedroom. Alford also says that she was with Kennedy during the Cuban Missile Crisis, and he confided in her that he’d rather have his children converted to communism than have them wind up dead in a war. Alford, who ended the affair because she was getting married, also helped console the president after the death of his son Patrick.
