Those conclusions, contained in 28 pages of the report, still have not been released publicly.
The dispute comes as bipartisan criticism is growing in Congress about Washington’s alliance with Saudi Arabia, for decades a crucial American ally in the Middle East and half of a partnership that once received little scrutiny from lawmakers. Last week, two senators introduced a resolution that would put restrictions on American arms sales to Saudi Arabia, which have expanded during the Obama administration.
Families of the Sept. 11 victims have used the courts to try to hold members of the Saudi royal family, Saudi banks and charities liable because of what the plaintiffs charged was Saudi financial support for terrorism. These efforts have largely been stymied, in part because of a 1976 law that gives foreign nations some immunity from lawsuits in American courts.
The Senate bill is intended to make clear that the immunity given to foreign nations under the law should not apply in cases where nations are found culpable for terrorist attacks that kill Americans on United States soil. If the bill were to pass both houses of Congress and be signed by the president, it could clear a path for the role of the Saudi government to be examined in the Sept. 11 lawsuits.
