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. troops had turned out to be long-sought mobile "biological laboratories." He declared, "We have found the weapons of mass destruction."... 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. Report shelved while claim went forth The three-page field report and a 122-page final report three weeks later were stamped "secret" and shelved. Meanwhile, for nearly a year, administration and intelligence officials continued to publicly assert that the trailers were weapons factories.
