I try not to get too verbose in the original posting but here's another excerpt from the article that addresses your concern:
"On April 23, 2006, CBS's "60 Minutes" interviewed Tyler Drumheller, the former CIA chief of clandestine operations for Europe, who disclosed that the agency had received documentary intelligence from Naji Sabri, Saddam's foreign minister, that Saddam did not have WMD. "We continued to validate him the whole way through," said Drumheller. "The policy was set. The war in Iraq was coming, and they were looking for intelligence to fit into the policy, to justify the policy."
Both the French intelligence service and the CIA paid Sabri hundreds of thousands of dollars (at least $200,000 in the case of the CIA) to give them documents on Saddam's WMD programs. "The information detailed that Saddam may have wished to have a program, that his engineers had told him they could build a nuclear weapon within two years if they had fissile material, which they didn't, and that they had no chemical or biological weapons," one of the former CIA officers told me.
On the eve of Sabri's appearance at the United Nations in September 2002 to present Saddam's case, the officer in charge of this operation met in New York with a "cutout" who had debriefed Sabri for the CIA. Then the officer flew to Washington, where he met with CIA deputy director John McLaughlin, who was "excited" about the report. Nonetheless, McLaughlin expressed his reservations. He said that Sabri's information was at odds with "our best source." That source was code-named "Curveball," later exposed as a fabricator, con man and former Iraqi taxi driver posing as a chemical engineer."
