Former Nebraska Sen. Bob Kerrey, 57, has married his longtime companion, former “Saturday Night Live” writer Sarah Paley, age undisclosed, at a ceremony in New York on Friday, the ex-politico, who is now president of the New School for Social Research in Manhattan, told the Omaha World-Herald newspaper. This is Kerrey’s second marriage. His first ended in 1979. In the mid-’80s, during the time he was governor (a Democrat), he dated “Terms of Endearment” actress Debra Winger.
