“On May 28 [2003], the CIA released a new and extraordinary six-page report declaring that a critical part of the prewar WMD case had been proven right. Earlier in the month, the Pentagon had announced the discovery of a tractor trailer outfitted with industrial equipment and maintained it was one of the mobile biological weapons labs that had been graphically described by [Secretary of State Colin] Powell in his UN presentation. …The agency’s report…dismissed one explanation for the trailers that had been offered by senior Iraqi officials–that they were to produce hydrogen for artillery weather balloons.”
