On May 29, 2003, 50 days after the fall of Baghdad, President Bush proclaimed a fresh victory for his administration in Iraq: Two small trailers captured by U.S. and Kurdish troops had turned out to be long-sought mobile "biological laboratories." He declared, "We have found the weapons of mass destruction."

The claim, repeated by top administration officials for months afterward, was hailed at the time as a vindication of the decision to go to war. But even as Bush spoke, U.S. intelligence officials possessed powerful evidence that it was not true.

A secret fact-finding mission to Iraq -- not made public until now -- had already concluded that the trailers had nothing to do with biological weapons. Leaders of the Pentagon-sponsored mission transmitted their unanimous findings to Washington in a field report on May 27, 2003, two days before the president's statement.The media would have us think, 'better late than never.' But, the media and Congress should go down in flames with him.
