From that ZH article:
>Of course, the notion that "rogue operatives" (as the WSJ described them) were responsible for killing Khashoggi was first floated this morning by President Trump, who clarified that this theory was merely speculation on his part. The fact that this now appears to be the story that the Saudis are going with is certainly interesting, to say the least.
