A CIA supervisor added, "Clearly we had it at one point, we understood, we had concerns about the source, but over time it started getting used again and there really was a loss of corporate awareness that we had a problem with the source."
Part of the challenge facing U.S. intelligence agencies was the sheer volume of "defectors" shepherded into debriefing rooms by the INC and the appeal of their information to U.S. policymakers.
"Source Five," for instance, claimed that Osama bin Laden had traveled to Baghdad for direct meetings with Saddam Hussein. "Source Six" claimed that the Iraqi population was "excited" about the prospects of a U.S. invasion to topple Hussein. Plus, the source said Iraqis recognized the need for post-invasion U.S. control.
By early February 2003, as the final invasion plans were underway, U.S. intelligence agencies had progressed up to "Source Eighteen," who came to epitomize what some analysts still suspected -- that the INC was coaching the sources.
As the CIA tried to set up a debriefing of Source Eighteen, another Iraqi exile passed on word to the agency that an INC representative had told Source Eighteen to "deliver the act of a lifetime." CIA analysts weren't sure what to make of that piece of news -- since Iraqi exiles frequently badmouthed each other -- but the value of the warning soon became clear.
U.S. intelligence officers debriefed Source Eighteen the next day and discovered that "Source Eighteen was supposed to have a nuclear engineering background, but was unable to discuss advanced mathematics or physics and described types of "nuclear' reactors that do not exist," according to the Senate Intelligence Committee report.
"Source Eighteen used the bathroom frequently, particularly when he appeared to be flustered by a line of questioning, suddenly remembering a new piece of information upon his return. During one such incident, Source Eighteen appeared to be reviewing notes," the report said.
Not surprisingly, the CIA and DIA case officers concluded that Source Eighteen was a fabricator. But the sludge of INC-connected misinformation and disinformation continued to ooze through the U.S. intelligence community and to foul the American intelligence product -- in part because there was little pressure from above demanding strict quality controls.
Other Iraqi exile sources -- not directly connected to the INC -- also supplied dubious information, including a source for a foreign intelligence agency who earned the code name "Curve Ball." He contributed important details about Iraq's alleged mobile facilities for producing agents for biological warfare.
Tyler Drumheller, former chief of the CIA's European Division, said his office had issued repeated warnings about Curve Ball's accounts. "Everyone in the chain of command knew exactly what was happening," Drumheller said. [Los Angeles Times, April 2, 2005]
Despite those objections and the lack of direct U.S. contact with Curve Ball, he earned a rating as "credible" or "very credible," and his information became a core element of the Bush administration's case for invading Iraq.
Drawings of Curve Ball's imaginary bio-weapons labs were a central feature of Secretary of State Powell's presentation to the U.N.
Even after the invasion, U.S. officials continued to promote these claims, portraying the discovery of a couple of trailers used for inflating artillery balloons as "the strongest evidence to date that Iraq was hiding a biological warfare program." [CIA-DIA report, "Iraqi Mobile Biological Warfare Agent Production Plants," May 16, 2003]
Finally, on May 26, 2004, a CIA assessment of Curve Ball said "investigations since the war in Iraq and debriefings of the key source indicate he lied about his access to a mobile BW production product."
