Washington (CNN) – President Barack Obama gave the go-ahead for U.S. forces to raid a northern Pakistan housing compound based on "what was probably a 50-50 case that Osama bin Laden was there," his national security adviser said.
On April 28, Obama attended the last of several National Security Council meetings focused on finding and going after the al Qaeda leader. During that meeting, some advocated for the commando raid while others advised against it, according to National Security Adviser Tom Donilon, given there had been no clear-cut sightings of bin Laden by that point.FULL STORY
