Fourteen years after its completion, the full record of Congress’s investigation into the 9/11 attacks has not been published. Twenty-eight pages are still being withheld amid suspicions that what they contain could implicate the Saudi government and Saudi citizens in the terrorist strike.

President George W. Bush ordered the pages kept secret in 2002. In 2014, prodded by some of the 9/11 families, President Obama asked intelligence officials to work on declassifying the material. The process is still dragging on. The 28 pages should be released immediately. Americans still do not know exactly why 15 out of the 19 hijackers from Al Qaeda were Saudi citizens and whether that indicates efforts by influential Saudis, including in the powerful religious establishment, to support the plot. Former Senator Bob Graham, who was a co-chairman of the 2002 joint congressional inquiry into the attacks, has long claimed there is evidence of complicity by institutions and people beyond the 19 terrorists.

The Saudi government has long denied any involvement and that view was largely supported by the 9/11 Commission, an independent bipartisan panel that conducted a separate inquiry in 2004 and found “no evidence that the Saudi government as an institution or senior Saudi officials” funded Al Qaeda. Still, questions remain about the work of a number of Saudi-sponsored charities with financial links to Al Qaeda.

As Ben Rhodes, a White House official, said Monday, while it was not Saudi government policy to support Al Qaeda, “There were a number of very wealthy individuals in Saudi Arabia who would contribute, sometimes directly, to extremist groups, sometimes to charities that … ended up being ways to launder money to these groups.”
