US Senator believes Saudi Prince was responsible for journalist killing

A leading Republican U.S. senator said on Sunday he believed Saudi Crown Prince Mohammed bin Salman was responsible for the death of dissident journalist Jamal Khashoggi, and the Saudis have lost all credibility in their explanations of his death.

"Yes, I think he did it," Senator Bob Corker, chairman of the Senate Foreign Relations Committee, said in an interview with CNN's "State of the Union."
