** ADVANCE FOR SATURDAY MARCH 11 ** Hillary Clinton is interviewed and photographed in Chicago in this file photo of March 16, 1992, during the presidential campaign for her husband, Bill Clinton. Hillary Clinton served on Wal-Mart's board of directors for six years when her husband was governor of Arkansas, resigning in May 1992 two months after this photo was taken, and now is feeling political heat over her deep ties to Wal-Mart.
