You’ve gotta love it:

The Bush administration put relentless pressure on interrogators to use harsh methods on detainees in part to find evidence of cooperation between al Qaida and the late Iraqi dictator Saddam Hussein’s regime, according to a former senior U.S. intelligence official and a former Army psychiatrist.

Such information would’ve provided a foundation for one of former President George W. Bush’s main arguments for invading Iraq in 2003. No evidence has ever been found of operational ties between Osama bin Laden’s terrorist network and Saddam’s regime. …

A former senior U.S. intelligence official familiar with the interrogation issue said that Cheney and former Defense Secretary Donald H. Rumsfeld demanded that the interrogators find evidence of al Qaida-Iraq collaboration.

“There were two reasons why these interrogations were so persistent, and why extreme methods were used,” the former senior intelligence official said on condition of anonymity because of the issue’s sensitivity.

“The main one is that everyone was worried about some kind of follow-up attack (after 9/11). But for most of 2002 and into 2003, Cheney and Rumsfeld, especially, were also demanding proof of the links between al Qaida and Iraq that (former Iraqi exile leader Ahmed) Chalabi and others had told them were there.”

Nice.
