Theory on Khashoggi:
Khashoggi and Brennan/CIA have been selling SA illegal arms/weapons for a long time.
SA was buying about 1/2 from these illegal arms dealers and the other 1/2 above board from the U.S.
Trump told MBS that if he stopped buying the illegal weapons, Trump would sell him ALL the weapons he wanted legally.
SA had to take out Khashoggi because he would cause trouble. And, this is why Brennan and the CIA is so pissed off. Trump cut their illegal weapons dealing off.
And this is why Trump and Pompeo want to clear MBS/SA because it was part of the plan.
It seems Gina CIA is dirty.
