It was quite a while ago. During the run-up to the Iraq invasion when people were still debating how much time to give Saddam, what to do about the inspectors, etc.

The interview basically went "Well, he used CW on the Kurds and we sold him WMDs to fight the Iranians - we just don't know what he did with THAT stuff". Later in the interview the guy said a lot of the WMDs would have lost their effectiveness by now and would be about as dangerous as very toxic waste.

If pressed, I think it was the interviewer who said "So it's like we have the receipts?"
