NATIONAL JOURNAL: What Bush Was Told About Iraq (03/02/2006): "Two highly classified intelligence reports delivered directly to President Bush before the Iraq war cast doubt on key public assertions made by the president, Vice President Cheney, and other administration officials as justifications for invading Iraq and toppling Saddam Hussein, according to records and knowledgeable sources.

The disclosure that Bush was informed of the DOE and State dissents is the first evidence that the president himself knew of the sharp debate within the government over the aluminum tubes during the time that he, Cheney, and other members of the Cabinet were citing the tubes as clear evidence of an Iraqi nuclear program. Neither the president nor the vice president told the public about the disagreement among the agencies.
When U.S. inspectors entered Iraq after the fall of Saddam's regime, they determined that Iraq's nuclear program had been dormant for more than a decade and that the aluminum tubes had been used only for artillery shells.
The second classified report, delivered to Bush in early January 2003, was also a summary of a National Intelligence Estimate, this one focusing on whether Saddam would launch an unprovoked attack on the United States, either directly, or indirectly by working with terrorists.
The report stated that U.S. intelligence agencies unanimously agreed that it was unlikely that Saddam would try to attack the United States"
