On 4 December 2018, a group of United States senators were briefed by CIA Director Gina Haspel on the murder of Khashoggi. After the briefing, the senators were more than certain that bin Salman played a major role in the killing.[219] Senator Lindsey Graham said, "You have to be willfully blind not to come to the conclusion that this was orchestrated and organised by people under the command of MBS and that he was intrinsically involved in the demise of Mr. Khashoggi." Senator Bob Corker said that the prince "ordered, monitored, the killing" and "If he were in front of a jury, he would be convicted of murder in about 30 minutes."[220] On 5 December 2018, UN Human Rights chief Michelle Bachelet asked for an international investigation to determine who was behind Khashoggi's murder.[221]
