It isn't clear whether any of this matters any more politically, but the Pentagon-funded Iraqi National Congress wasn't just misleading the Bush administration, they were misleading the U.S. press as well. Details in this Knight-Ridder report. An excerpt:
A June 26, 2002, letter from the Iraqi National Congress to the Senate Appropriations Committee listed 108 articles based on information provided by the Iraqi National Congress's Information Collection Program, a U.S.-funded effort to collect intelligence in Iraq.
The Information Collection Program was financed out of the at least $18 million that the U.S. Congress approved for the Iraqi National Congress, led by Ahmed Chalabi, now a member of the Iraqi Governing Council, from 1999 to 2003. The group remains on the Pentagon's payroll.
The assertions in the articles reinforced President Bush's claims that Saddam Hussein should be ousted because he was in league with Osama bin Laden, was developing nuclear weapons and was hiding biological and chemical weapons.
Feeding the information to the news media, as well as to selected administration officials and members of Congress, helped foster an impression that there were multiple sources of intelligence on Iraq's illicit weapons programs and links to bin Laden.
In fact, many of the allegations came from the same half-dozen defectors, were not confirmed by other intelligence and were hotly disputed by intelligence professionals at the CIA, the Defense Department and the State Department.
Nevertheless, U.S. officials and others who supported a pre-emptive invasion quoted the allegations in statements and interviews without running afoul of restrictions on classified information or doubts about the defectors' reliability.
