Saudi Arabia's young crown prince has an ambitious list of to-dos: modernize his conservative kingdom, weaken Iran's hand across the Mideast and, this week, rehabilitate his country's image in the eyes of Americans. Crown Prince Mohammed bin Salman, son of King Salman and heir to the throne, is opening a marathon tour of the United States with a stop in Washington, where he plans to meet President Donald Trump today. He'll hold separate meetings with a long roster of influential US officials, including the secretaries of defense, treasury and commerce, the CIA chief and congressional leaders from both parties.
