The Obama administration will likely soon release at least part of a 28-page secret chapter from a congressional inquiry into 9/11 that may shed light on possible Saudi connections to the attackers, reports the Associated Press.

The documents, kept in a secure room in the basement of the Capitol, contain information from the joint congressional inquiry into "specific sources of foreign support for some of the Sept. 11 hijackers while they were in the United States."

Bob Graham, who was co-chairman of that bipartisan panel, and others say the documents point suspicion at the Saudis. The former Democratic senator from Florida says an administration official told him that intelligence officials will decide in the next several weeks whether to release at least parts of the documents. The disclosure would come at a time of strained U.S. relations with Saudi Arabia, a long-time American ally.

"I hope that decision is to honor the American people and make it available," Graham told NBC's "Meet the Press" on Sunday. "The most important unanswered question of 9/11 is, did these 19 people conduct this very sophisticated plot alone, or were they supported?"
