Ron Paul was booed at the CNN/Tea Party Republican debate on Monday night after saying that al Qaeda did not attack the United States because "we're free," but because of U.S. military operations in the Middle East and the nation's "unfair" treatment of Palestinians.

"This whole idea that the whole Muslim world is responsible for this and their attacking us because we're free and prosperous, that is just not true," he said, eliciting some cheers from the crowd.

But as he continued, the cheers were drowned out with boos.

"Osama bin Laden and al Qaeda have been explicit, and they wrote and said that we attacked because you had bases on our holy lands in Saudi Arabia, you do not give Palestinians a fair treatment," Paul said before being interrupted by more boos. "I didn't say that, I'm just trying to get you to understand what the motive was behind the bombings."
