The Silberman-Robb Commission’s report, which was released on March 31, 2005, quoted from the Iraq Survey Group’s (ISG) Interim Report, which was released on October 3, 2003. ” ‘With respect to mobile BW [biological weapons] production facilities, the *ISG found no evidence that Iraq possessed or was developing production systems on road vehicles or railway wagons.* The ISG’s *exhaustive investigation* of the two trailers captured by Coalition forces in spring 2003 revealed that the trailers were *almost certainly designed and built exclusively for the generation of hydrogen.* The ISG judged that the trailers *cannot…be part of any BW program.* ‘ “
