JEFFREY BROWN:

Twenty-eight pages of a joint congressional inquiry into the 9/11 attacks were classified by the George W. Bush administration, which claimed they contained information that would hurt the war on terror.

But some lawmakers argue the pages reveal little about national security and a great deal about the government of Saudi Arabia's role in the attacks. They say that the pages tell the story of Saudi officials meeting with and even funding two of the 9/11 hijackers when they first arrived in the U.S.

It's all in a story by Lawrence Wright in this week's "New Yorker" magazine. Wright is author of "The Looming Tower" about events leading to the 9/11 attack. His new book is "Thirteen Days in September: Carter, Begin, and Sadat at Camp David."

And he joins me now.

And welcome back, Larry Wright. So this is a 9/11 story about what we still don't know. Put those 28 pages in context first. They're part of the original investigation into what happened, but only a handful of people have seen them, right?
