“You’ll never convince me that he didn’t do this,” Graham told Bartiromo on Sunday Morning Futures.

Even after the Saudi quasi-confession, Trump defended the crown prince, known as MbS. On Friday, Trump said he found the Saudi fistfight claim credible. By Saturday night, he sounded a bit more skeptical in a Washington Post interview: “Obviously there’s been deception, and there’s been lies,” he said, noting that the Saudis’ “stories are all over the place.” The monarchy has pinned blame on underlings of MbS, whom Trump has called “a strong person—he has very good control.”

Graham thinks MbS shouldn’t have control any longer. Three days before the Saudis acknowledged the journalist’s death, the senator said the crown prince “has got to go.” On Fox & Friends, the chatty morning show the president is prone to join by telephone, Graham had argued the royal must be culpable because “nothing happens in Saudi Arabia without MbS knowing it.”
