In this 2005 interview, former INR official Wayne White discussed the intelligence that INR saw RE: Iraq’s chemical and biological weapons program

But on CW and BW, we were as wrong as anyone else. Therefore, it was good that there was a review of the evidence on that because, honestly, I have never seen more Humint on something that apparently no longer existed – Humint in one instance which was not generated by the CIA or State or any U.S. government source, which was utterly convincing to me and incredibly specific. We are not talking about three or four reports, but rather 20 or 30, as I recall. There have been developments that were true and actually had been happening on various Middle East issues for which I only saw two or three reports and deemed them to be correct. It was amazing how much disinformation was thrown at us. A lot of it came from Ahmad Chalabi and his INC, who of course wanted to get back into Iraq. He knew the only way to do that was to get the U.S. to do it militarily.
