President Barack Obama said in an interview Osama bin Laden had some support network in Pakistan and said it would take investigations from both the United States and Pakistan to determine exactly who.

We think that there had to be some sort of support network for bin Laden inside of Pakistan. But we don't know who or what that support network was, Obama told CBS' 60 Minutes program in an interview originally taped on Wednesday and set to air on Sunday.

And we've already communicated to them, and they have indicated they have a profound interest in finding out what kinds of support networks bin Laden might have had.

He said that it would take some time to exploit the intelligence that we were able to gather on site.
