In response to a letter from Senator Bob Graham of the Senate Intelligence Committee (see October 4, 2002), the CIA agrees to declassify three passages from the National Intelligence Estimate on Iraq (see October 1, 2002) that said Saddam Hussein is unlikely to use chemical or biological weapons unless he is attacked. The CIA also agrees to release a portion of the October 2 exchange between Graham and Deputy CIA Director John McLaughlin, in which McLaughlin stated that the probability that Saddam would initiate and attack was low (see October 2, 2002). Finally, in response to Graham’s request for additional information on alleged links between Iraq and al-Qaeda, the CIA says its “understanding of the relationship… is evolving and is based on sources of varying reliability. Some of the information… received comes from detainees, including some of high rank.” [Central Intelligence Agency, 10/7/2002; CBC News, 11/1/2002]
