U.S. Senator Lindsey Graham said on Tuesday that he had "high confidence" that Saudi Crown Prince Mohammed bin Salman, known as MBS, was complicit in the killing of Jamal Khashoggi.

Graham, the South Carolina Republican, made the comments after a private CIA briefing that MBS had a role in the murder of Khashoggi.

According to the BBC, he described the Saudi royal as "a wrecking ball", "crazy" and "dangerous".
