On Tuesday, over the protestations of the Obama administration, the Senate unanimously passed a bill allowing families of 9/11 victims to sue Saudi Arabia for any involvement it may have had in the plot to perpetrate those attacks.

Fifteen years after 9/11, the American public still doesn’t know if elements in the government of Saudi Arabia, an American strategic ally and client state, aided the hijackers. But according to once-secret U.S. government notes declassified last year, one of the conspirators, arrested in Pakistan in 2002, was found with what could be a clue.

At a campaign event in Bluffton, South Carolina, on Wednesday morning, Donald Trump, in the midst of a rant about how much he doesn’t like Lindsey Graham, seemed to imply that, if elected president, he would reveal the true perpetrators of the 9/11 terror attacks.

True to form, the CIA waited until 4:16 p.m. EDT this afternoon to release a trove of documents related to the September 11 attacks. Deep within one of those documents is a section on everything the agency learned after 9/11 about “Issues Relating to Saudi Arabia.” We can now share it here for the first time.
