According to an Associated Press story, he was on a list of Bernard Madoff’s clients that was made public yesterday. Here is a two-graf excerpt from the story, with a link to the full story below:

NEW YORK (AP) — Hall of Fame pitcher Sandy Koufax. Actor Kevin Bacon. World Trade Center developer Larry Silverstein.
All three have at least one thing in common: Their names appear on a list of several thousand clients who invested with Bernard Madoff. The list has been made public in a court filing in U.S. Bankruptcy Court in Manhattan.
The list emerged late Wednesday, shortly after a whistleblower in the case, Harry Markopolos, told House lawmakers at a hearing that he had discovered that additional funds had relayed investments to Madoff in Europe _ and that the managers of these “feeder” funds may have ignored signs of the massive fraud scheme.
