A controversy about 28 redacted pages from the 9/11 report that has been simmering for years is coming to the fore again as President Obama prepares to visit Saudi Arabia. At issue is a classified section of the report that it has long been believed details involvement by the Saudi Arabian government in the attack on America on September 11, 2001. President Obama has promised 9/11 families twice that he would declassify the documents but has failed to follow through.
