Story highlights Expect a decision in June

Ex-Sen. Bob Graham was briefed on progress

(CNN) The review process surrounding the decision to release 28 classified pages from a joint congressional report that focus on alleged Saudi Arabian involvement in the September 11 attacks is in its final stages, former Sen. Bob Graham told CNN on Wednesday.

Graham, the co-chairman of the 2002 congressional inquiry that has led the push to have the documents released to the public, was given an update on the review process in an hour-long meeting with Director of National Intelligence James Clapper on Tuesday evening.

"(Clapper) is just about finished in his review and will be handing it off to an inter-agency group," Graham said. That group includes intelligence, law enforcement and defense agencies.

President Barack Obama is expected to make a decision on whether to release the documents in June, a schedule that Graham believes is still on track.

"It appears as if the schedule that the President had set back in April is still holding. There will be a decision sometime in June," Graham said. "I hope as early in the month as possible."
