"In April, Saudi Arabia warned it would start selling as much as $750 billion in Treasuries and other assets if Congress passes a bill allowing the kingdom to be held liable in U.S. courts for the Sept. 11 terrorist attacks, according to the New York Times. The threat comes amid a renewed push by presidential candidates and legislators from both the Democratic and Republican parties to declassify a 28-page section of a 2004 U.S. government report that is believed to detail possible Saudi connections to the attacks. The bill, which passed the Senate on May 17, is now in the House of Representatives.
"Saudi Arabia’s Finance Ministry declined to comment on the potential selling of Treasuries in response. The Saudi Arabian Monetary Agency didn’t immediately answer requests for details on the total size of its U.S. government debt holdings."
