Push to declassify top-secret '28 pages' on 9/11

There is a renewed push to have U.S. government officials declassify 28-pages redacted from a top-secret 9/11 investigative report.

"I think they are a key part," Bob Graham, the former Florida governor, Democratic U.S. Senator and onetime chairman of the Senate Select Committee on Intelligence, told '60 Minutes' on Sunday.

Graham believes the 28-pages, which were removed by the Bush Administration in the interest of national security, would shed light on possible Saudi support for some of the 9/11 hijackers.

According to Graham, the terrorists were "substantially" supported by Saudi Arabia. 

"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," said Graham.

The former politician helped co-author the report while he served as co-chair of Congress' bipartisan "Joint Inquiry" into intelligence failures surrounding the attacks on Sept. 11, 2001.

The report was issued in 2003.

There have been various attempts over the years that have failed to put pressure on the Obama administration to order the declassification of the pages.

According to Graham, the Saudis are on board with the declassification of the top-secret papers as are other politicians and relatives of the terror attack's victims.
