LET’S BE clear: The Saudi “investigation” of the disappearance of journalist Jamal Khashoggi, which the Trump administration contends needs to be given more time to reach conclusions, does not exist. The Saudi leadership under King Salman and Crown Prince Mohammed bin Salman, like the Turkish government, knows very well what happened inside the Saudi Consulate in Istanbul on the afternoon of Oct. 2. Though they pretend otherwise, so do President Trump and his top aides, who have access to U.S. intelligence reports that are being withheld from Congress.
