The panel's investigators have said there was no collaborative relationship between Hussein's regime and the Al-Qaeda terrorist network.
But Bush said there were ties between Saddam Hussein's regime and terrorists before the 11 September attacks that killed roughly 3,000 people.
"He [Saddam Hussein] was a threat because he was a sworn enemy to the United States of America, just like Al-Qaeda. Now, he was a threat because he had terrorist connections, not only Al-Qaeda connections but other connections to terrorist organizations," Bush said.
The Bush administration sought to justify the Iraq war, in part, based on Hussein's alleged ties with terrorists. It also argued that Hussein had weapons of mass destruction -- which have not been found -- and that he ruled his country by terror and intimidation.
