In 2000, presidential candidate George W. Bush demanded Vice President Al Gore release various documents related to his past. He said on March 15, 2000, "I challenge you to clear the air on some serious charges. I hope you will encourage the White House and the Department of Justice to release all records and photographs relating to the investigation of fundraising." But now, facing far more serious allegations than fundraising irregularities, the President has categorically refused to release critical documents in a host of areas.
