Powell said that the CIA and DIA should face questions about why they failed to sound the alarm about Janabi. He demanded to know why it had not been made clear to him that Curveball was totally unreliable before false information was put into the key intelligence assessment, or NIE, put before Congress, into the president’s state of the union address two months before the war and into his own speech to the UN.

“It has been known for several years that the source called Curveball was totally unreliable,” he told the Guardian . “The question should be put to the CIA and the DIA as to why this wasn’t known before the false information was put into the NIE sent to Congress, the president’s state of the union address and my 5 February presentation to the UN.”
