The withheld section of the official report on the 2001 attacks is central to a dispute over whether Americans should be able to sue the Saudi Arabian government for damages. The Office of the U.S. Director of National Intelligence is reviewing the material to see whether it can be declassified. Former Sen. Bob Graham, a Florida Democrat, has been pressing for the release of the information and said that it may shed light on the financial backers for 19 hijackers who killed nearly 3,000 people on Sept 11, 2001. Graham told NBC's Meet the Press "The president’s staff at least has said that they will make a decision by June, and I hope that decision is to honor the American people and make it available."
