official white house pictures show president obama and members of his national security team as they watched a live feed of the operation. you get an idea of how tense those 40 minutes were during the raid. also gathered around, secretary of state hillary clinton, vice president joe biden and john brennan. he described it as time passing like days and it was the work of the special operations forces. here's the latest on the raid and the impending investigation. >> three simultaneous investigations this morning, some in congress wanting to look more deeply into how bin laden has aided capture for so long. senators getting a cia briefing today. then the pakistani government claiming it did not know bin laden was on its soil says it is investigating. and finally the cia poring over a treasure trove of information about the raid and figuring out what we need to know and what we do not. >> they're waiting for the code word, geronimo, to indicate success. >> we were not confident the mission was a success until all of our brave soldiers were able to come out and bring the body out. >> finally, a transmission from the ground commander. for god and country, he said, geronimo, geronimo, geronimo. we know two special ops teams infiltrated the property. one commando put two bullets in bin laden's head. his body was flown to vin where he was put to sea. this shows bin laden's

in plain sight for so long? >> i have to say i was surprised to learn where he was found. i think the general sense is that he was probably someplace up in the tribal areas. >> clearly there is some type of support network that provided him assistance. >> and did water boarding giving essential clues to bin laden's whereabouts. >> the enhanced interrogation program that we put in place produced some of the results that led to bin laden's ultimate capture. >> so there was no one critical bit of information that was provided by either a detainee or somebody else. what happened is it was a mosaic that was a over time. >> and will the white house and pentagon release video and photographic proof of bin laden's death? >> in pakistan, there is a level of disbelief about this entire operation. huge skepticism, huge cynicism, a different pakistani mindset when it comes to osama bin laden. really, that it did not happen. >> bottom line, they want to see more evidence, and this week they may get it. and that's because the white house and pentagon are seriously considering releasing more proof of bin laden's death, although brennan defends the administration so far saying they've been forthcoming with a lot of information just hours after this mission ended and they're carefully assessing what the reaction could be if photos and video are made public worldwide. barbara, back
