A declassified FBI document related to logistical support given to two of the Saudi hijackers in the run-up to the Sept. 11 attacks details contacts the men had with Saudi associates in the United States but does not provide proof that senior kingdom officials were complicit in the plot. The document released Saturday, on the 20th anniversary of the attacks, is the first investigative record to be disclosed since President Joe Biden ordered a declassification review of materials that for years have remained out of public view. The 16-page document is a summary of an FBI interview done in 2015 with a man who had frequent contact with Saudi nationals in the U.S. who supported the first hijackers to arrive in the country before the attacks. Biden ordered the Justice Department and other agencies to conduct a declassification review and release what documents they can over the next six months. He was under pressure from victims’ families, who have long sought the records as they pursue a lawsuit in New York alleging that Saudi government officials supported the hijackers. […] The Saudi government has long denied any involvement in the attacks.
