Saudi Crown Prince Mohammed bin Salman said Thursday it would be really insane" for him to trade classified information with presidential son-in-law and White House adviser Jared Kushner. Speaking in a meeting with Washington Post editors and reporters, Mohammed denied U.S. media reports that he had claimed Kushner was "in his pocket," or that ... he had sought or received a green light from Kushner for massive arrests of allegedly corrupt members of the royal family and Saudi businessmen that took place in the kingdom. The detentions were solely a domestic issue and had been in the works for years, the prince said. The son of King Salman and heir to the Saudi throne, Mohammed, 32, met with President Trump on Tuesday in the Oval Office and over lunch. He also spoke with a number of congressional leaders. Even as Trump has said he is seeking increased investment and purchases of U.S. military equipment and other products from Saudi Arabia, Mohammed has made clear that his primary mission here is to win U.S. investor confidence in his country. Asked about the Saudi-funded spread of Wahhabism, the austere faith ... that some have accused of being a source of global terrorism, Mohammed said that investments in mosques and madrassas overseas were rooted in the Cold War, when allies asked Saudi Arabia to use its resources to prevent inroads in Muslim countries by the Soviet Union. Successive Saudi governments lost track of the effort, he said.
