The CIA, meanwhile, is facing growing pressure to brief the full Senate, since Tuesday's briefing comprised only roughly a dozen senators from the party leadership and who sit on key committees. Lindsey Graham was only more convinced of the crown prince's involvement.
Saudi officials say the men acted on their own authority and did not receive instructions from bin Salman to murder Khashoggi, a Saudi dissident with legal residency in the United States.
Two weeks ago Trump said, "I don't know". "There are all sorts of things we can do to make clear this can't continue to happen".
"I think the secretary of defense and secretary of state are in a bad spot because the president has given this bear hug to MBS and to the entire Saudi regime so they are bound to carry out his freakish policy", Murphy said, using an acronym for the crown prince.
"The worldwide community seems to doubt Saudi Arabia's commitment to prosecute this heinous crime", the official said, adding that by extraditing all suspects to Turkey, "Saudi authorities could address those concerns".
Lindsey Graham of SC, the administration sent in CIA Director Gina Haspel to brief a select group of senators from key committees on the agency's findings about the Khashoggi killing. He said you'd have to be "willfully blind" to ignore the evidence and that there is "zero chance" that MBS is innocent in the matter.
The Tennessee Republican said that with the schedule changes necessitated by the funeral of President George H.W. Bush, floor debate would most likely come up on Monday, Dec. 10. Graham said that may be true, but there is certainly a "smoking bonesaw", alluding to the murder weapon suspected to have killed Khashoggi.
Saudi authorities say the agents who killed Khashoggi exceeded their authority.
Saudi Arabia has detained 21 people and seeking the death penalty for five. Secretary of Defense James Mattis was emphatic last week, telling reporters, "We have no smoking gun that the Crown Prince was involved".
"They have been a great ally in our very important fight against Iran", Trump said in the statement.
The U.S. has slapped sanctions on Saudis involved in the murder. Following the briefing, a handful of senators said they believe that MBS ordered the hit on Khashoggi.
Graham, who is a member of the armed services and foreign relations committees, told Fox News that he he could no longer support arms sales to Riyadh under Mohammed, who he called "a wrecking ball when it comes to the Mideast".
The United States now provides arms shipments and logistical support including intelligence and targeting assistance to the Saudi-led coalition, which includes the United Arab Emirates and other Arab countries.
Graham is one of the sponsors of the non-binding resolution.
