President of the United States Donald Trump, when asked if he believed this fist fight story over the previous ones that (1) the Saudis had no idea what anyone was talking about because Khashoggi left the Consulate in good health, and (2) Khashoggi died during an interrogation that accidentally went a little too far, he replied, "I do. I do." Donald Trump believes the fistfight story. (He likewise believed the previous explanations. Because Saudi Arabia has promised to buy - but has not yet bought - $110 billion in arms from the U.S. And because the Saudis do buy apartments and hotels from Donald Trump and have paid him lots of money since he took office).
I'll believe that a 60-year-old Washington Post journalist on his way to pick up some paperwork the day before his wedding, with his fiancée waiting outside for him, picked a fight with eighteen men and that he was so belligerent and powerful that he had to be killed.
Show me the body.
