There were some rumors that Obama watched the whole Bin Laden mission via a camera feed mounted on either the helicopter or a Navy Seal. I'm not sure that's true. (Edit: CNN says "kind of" with lots of qualifiers.)
This official White House photo release refers to this group "receiving an update." Still, it's pretty dramatic.
Edit: Man, so many people are saying "they watched a live feed of every second of it". That misinformation will go down in history as fact.
