Former U.S. Senator Bob Graham has once again called for the investigation of the terrorist attacks that rocked this country eleven years ago today, to be reopened.

He's focusing his request based upon what he calls the distrust that many feel surrounding the official story of how 9/11 happened.

Graham is a former co-chair of the Congressional Joint Inquiry into 9/11.

He called for a reopening last year and this latest request comes in an online column.

Graham says he felt he never got enough information during the time he co-chaired the investigation about who financed and supported the attacks and whether that can be tied to Saudi Arabia.
