[The Saudi investigation is merely] a poorly done coverup. Their story line is completely implausible—a team of fifteen killers travels to Istanbul where they take charge of a diplomatic facility with no instructions from the Saudi leadership and kill Jamal Khashoggi. The mastermind of the murder is undoubtedly the crown prince, which is why there is a coverup... The Treasury sanctions [targeting Saudi officials implicated in the Khashoggi assassination] are mostly symbolic. The Administration is trying desperately to save M.B.S. from the consequences of his poor judgment.
