As the 23rd anniversary of 9/11 approaches, Americans still don't have a full accounting of the role of a supposed U.S. ally, Saudi Arabia, in the terrorist attacks that killed nearly 3,000 people. The voids in our knowledge owe both to the Saudi government's opacity and denials ... as well as to our government's lid on information gleaned through federal investigations, a congressional inquiry and blue-ribbon commission. President Biden in 2021 finally ordered many documents declassified, fulfilling a promise to the 9/11 victims' families, but the releases were heavily redacted. "What we've uncovered, with no help from our FBI and no help from our own government, is that [the terrorists] had a significant amount of help, and that help came in the form of the Saudi government," Brett Eagleson, president of the families group 9/11 Justice, told reporters after a court hearing. The lawsuit turns on whether assistance from Saudi individuals and groups to two hijackers who had lived in San Diego was part of the Al Qaeda plot. Of the 19 attackers, 15 were Saudis, including the two in California who would commandeer the jetliner that they crashed into the Pentagon. Osama bin Laden belonged to one of Saudi Arabia's wealthiest clans. In a 1999 video first aired by CBS' "60 Minutes"in late June, Saudi citizen Omar Al Bayoumi " an informant to Saudi intelligence, the FBI confirmed, despite Saudi denials " surveills the U.S. Capitol ... presumably for his Al Qaeda handlers.
