Two intelligence sources tell NBC News that the year before the U.S. raid that killed Osama bin Laden, a "walk in" asset from Pakistani intelligence told the CIA where the most wanted man in the world was hiding - and these two sources plus a third say that the Pakistani government knew where bin Laden was hiding all along.
The U.S. government has always characterized the heroic raid by Seal Team Six that killed bin Laden as a unilateral U.S. operation, and has maintained that the CIA found him by tracking couriers to his walled complex in Abbottabad, Pakistan.
The new revelations do not necessarily cast doubt on the overall narrative that the White House began circulating within hours of the May 2011 operation. The official story about how bin Laden was found was constructed in a way that protected the identity and existence of the asset, who also knew who inside the Pakistani government was aware of the Pakistani intelligence agency's operation to hide bin Laden, according to a special operations officer with prior knowledge of the bin Laden mission. The official story focused on a long hunt for bin Laden's presumed courier, Ahmed al-Kuwaiti.
