the relations with the u.s. became strained following 9/11. american politicians and media accused the saudi government of supporting terrorism and tolerating a "jihadist" culture. indeed, osama bin laden and 15 out of the 19 9/11 hijackers were from saudi arabia; in isil-occupied raqqa, in mid-2014, all 12 judges were saudi. the leaked us department of state memo, dated 17 august 2014, says that "governments of qatar and saudi arabia...are providing clandestine financial and logistic support to isis and other radical groups in the region." according to former us secretary of state hillary clinton, "saudi arabia remains a critical financial support base for al-qaida, the taliban, let and other terrorist groups... donors in saudi arabia constitute the most significant source of funding to sunni terrorist groups worldwide." former cia director james woolsey described it as "the soil in which al-qaeda and its sister terrorist organizations are flourishing." the saudi government denies these claims or that it exports religious or cultural extremism. in april 2016, saudi arabia has threatened to sell off $750 billion in treasury securities and other us assets if congress passes a bill that would allow the saudi government to be sued over 9/11. in september 2016, the congress passed the justice against sponsors of terrorism act that would allow relatives of victims of the september 11 attacks to sue saudi arabia for its government's alleged role in the attacks. congress overwhelmingly rejected president barack obama's veto.
