William Barr

The White House press office did not immediately respond Wednesday to a request for comment on the families’ characterizations of the meeting. One day after that encounter, Justice Department officials agreed to release the name of one mid-level Saudi religious official who had been tied to the case in an FBI document that had been partially declassified earlier. At the same time, however, Barr asserted the state secrets privilege to protect other FBI documents sought by the families. The latest flurry of statements supporting that claim responded to challenges from the plaintiffs. Although the close alliance between the United States and the Saudi kingdom has survived countless moments of tension, it has frayed in recent months in ways that could prove helpful to plaintiffs in the 9/11 lawsuit. In recent weeks, Republican senators from states that have been hard hit by the collapse of world oil prices have criticized the Saudi government with growing intensity. On March 25, before the Trump administration negotiated a cut in Saudi oil production, Sen. Lisa Murkowski of Alaska cited the law under which the 9/11 families were allowed to sue the Saudi government as one of the levers of pressure that the United States could use if the kingdom did not take account of American concerns. In a letter on Monday, three other influential senators asked the Justice Department’s inspector general to examine in depth why the FBI has refused to disclose more information about Saudi connections to the plot in response to a subpoena filed by the 9/11 families in 2018. Those senators, Charles Grassley, the Iowa Republican, and two Democrats, minority leader Charles Schumer of New York and Richard Blumenthal of Connecticut, cited a recent investigative report by ProPublica and The New York Times Magazine that raised new questions about the FBI’s inquiry into the Saudi role in the attacks. “The September 11 attacks represent a singular and defining tragedy in the history of our Nation,” the senators wrote to the Justice Department inspector general, Michael Horowitz. “Nearly 20 years later, the 9/11 families and the American public still have not received the full and transparent accounting of the potential sources of support for those attacks to which they are entitled.”
