“On the morning of Wednesday, March 31 [2004], the head of ISG’s [Iraq Survey Group’s] chemical- and biological-weapons team, Rita, sent an Australian chemist and intelligence analyst, Vanessa, to investigate the site [the Al Abud Company]. Vanessa returned with photographs, an inventory of equipment, and other documents, including a copy of the mujahadeen ‘recipe book’ for chemical agents. Her assessment was that the First Cavalry raid had uncovered an ongoing effort to produce the toxin ricin. …The more Vanessa learned, the more alarmed she became. At the Al Abud lab, she found a container that was labeled triethanolamine (TEA), a chemical known as a precursor for the production of a nerve agent.”
