US intelligence chief John Brennan said that speculations the Saudis were involved in September 11 attacks are mistake because they would harm ties between Riyadh and Washington.

On a TV show on Sunday, that releasing the 28 classified pages from the 9/11 Commission report would be a mistake because they contain inaccurate, un-vetted information that could be used to tie Saudi Arabia to the Sept. 11, 2001.

"This chapter was kept out because of concerns about sensitive methods, investigative actions, and the investigation of 9/11 was still underway in 2002," Brennan said on NBC's "Meet the Press."

He said information in the 28 pages hasn't been vetted or corroborated, adding that releasing the information would give ammunition to those who want to tie the terror attacks to Saudi Arabia.

"I think there's a combination of things that are accurate and inaccurate [in the report]," Brennan said. "I think the 9/11 Commission took that joint inquiry and those 28 pages or so and followed through on the investigation and then came out with a very clear judgment that there was no evidence that ... Saudi government as an institution or Saudi officials or individuals had provided financial support to al Qaeda."

Former and current congressmen argue the pages show the existence of a Saudi support network for the hijackers involved in the terror attacks. The 28 pages were cut from a report on the 9/11 terror attacks in 2003 by the George W. Bush administration in the interest of national security.
