Senators from both parties have expressed dismay at the results of the delayed and incomplete CIA briefing on Jamal Khashoggi's murder, implying that Secretaries Pompeo and Mattis were not forthcoming at their own briefing the week before. Some senators have also publicly expressed clear views that Mohammed bin Salman ordered Khashoggi’s killing, counter to the White House narrative.
The big picture: The Khashoggi fallout has created a breach in confidence between the executive and legislative branches of government on national security, even while the same political party controls both branches. When Democrats take control of the House next month, tensions are likely to worsen.
