His investors may not have been the only ones Bernie Madoff cheated: sources tell the New York Daily News that the Ponzi schemer had at least one extramarital affair . He was involved with an executive assistant at a big media firm "eight or nine years ago," one insider tells the News. “He was quite generous with her. He used to fly her around,” the source said. Ruth Madoff found out and “kept him on a short leash after that,” said another.
