More than two dozen top secret investigative pages that contributed to the government's official 9/11 report were finally released Friday, following years of pressure from lawmakers, leery conspiracy theorists and relatives of some of the victims.

The 29-pages of raw intelligence material, compiled by congressional investigators months after the Sept. 11, 2001, terrorist attacks, addresses potential connections between some of the al-Qaida hijackers and the Saudi Arabian government.

The House Intelligence Committee has made public most of a long-classified section of a 2002 congressional inquiry into 9/11 attacks that discusses the alleged role of Saudi Arabia.

The release follows many months of vetting by the Obama administration and growing demands by relatives of those killed in the 2001 attacks as well as other critics of the Saudis.

Amid the clamor a year ago to release 28 still-secret pages of a congressional inquiry into the Sept. 11 attacks, the government quietly declassified a little-known report listing more than three dozen people who piqued the interest of investigators probing possible Saudi connections to the hijackers.

The document, known as "File 17," offers clues to what might be in the missing pages of the bipartisan report about 9/11.

CIA chief John Brennan said on Sunday he expects 28 classified pages of a U.S. congressional report into the Sept. 11, 2001 attacks on the United States to be published, absolving Saudi Arabia of any responsibility.

“I think the 28 pages will be published and I support their publication and everyone will see the evidence that the Saudi government had nothing to do with it,” Brennan said in an interview with Saudi-owned Arabiya TV. His comments were dubbed into Arabic.
