The Saudi role in September 11 attacks gained new attention after two former U.S. senators, co-chairmen of the Conressional Inquiry into the attacks, told CBS in April 2016 that the redacted pages of the Congressional Inquiry′s refer to evidence of Saudi Arabia′s substantial involvement in the execution of the attacks, and calls renewed to have the redacted pages released. Fifteen of the 19 hijackers were Saudi citizens. Aftermath The Saudi government has long denied any connection. Relatives of victims have tried to use the courts to hold Saudi royals, banks, or charities responsible, but these efforts have been thwarted partly by a 1976 law giving a foreign government immunity. In March 2016 Saudi Foreign Minister Adel al-Jubeir threatened to Obama and lawmakers to sell $750,000,000,000 worth of American assets owned by Saudi Arabia if bills clarifying that the 1976 law giving a foreign government immunity does not apply to terror acts, were passed . There are some fears that this could destabilize the US dollar.
