WASHINGTON - A former US senator has called for the declassification of a top-secret 9-11 report he helped write. On CBS' "60 Minutes" news programme, former Senator Bob Graham, a Democrat, said that the public should see 28 pages about possible Saudi support for some 9-11 hijackers. Graham, co-chair of Congress' bipartisan Joint Inquiry into intelligence failures before the 2001 attacks, says the 28 pages outline a network of people he believes supported the hijackers in the United States.

“I think its implausible to believe that 19 people, most of whom didn't speak English, most of whom had never been in the United States before, many didn't have a high school education, could have carried out such a complicated task without some support from within the United States," Graham said.

Graham says he believes the hijackers were "substantially" supported by Saudi Arabia. When asked if that support was from government, rich people or charities, Graham replies: "All of the above." Graham and former Congressman Porter Goss, a Republican, say the Bush administration excised the 28 pages in the interest of national security. Goss was Graham's Joint Inquiry co-chair in the House and went on to become director of the CIA.

Other current and former members of Congress, US officials and families of the attacks' victims want the 28 pages released.

Graham and others say protecting Saudi Arabia was the reason for classifying the pages.

Other speakers in the "60 Minutes" segment include former U.S. Senator Bob Kerrey, former Navy Secretary John Lehman and lawyers for attack victims' relatives who are suing Saudi Arabia.

Former US Congressman Tim Roemer from Indiana says it's time that everyone know the top-secret contents. He served on both Congress' Joint Inquiry and the 9/11 Commission. "Look, the Saudis have even said they're for declassifying it. We should declassify it," Roemer tell Kroft. "Is it sensitive ... a bit of a can of worms or some snakes crawling out of there? Yes."
