Defense Secretary James Mattis has stated recently that there was no smoking gun concerning the matter. Trump also received backlash recently when he stated bin Salman may or may not have had knowledge of the murder.
Republican Senators Lindsey Graham (S.C.) and Bob Corker (Tenn.) said the CIA left little doubt that Saudi Arabian Crown Prince Mohammed bin Salman (MBS) was complicit in the murder of activist and writer Jamal Khashoggi.
CIA Director Gina Haspel briefed two Senate committees on Capitol Hill Tuesday on the CIA's findings about the murder of Khashoggi.
"There's not a smoking gun, there's a smoking saw," said Graham, adding that anyone who would deny bin Salman's involvement at this point is "willfully blind."
Corker agreed, saying there is "zero question" in his mind that MBS planned the murder and kept tabs on the events as they were unfolding.
