Oregon Senator Ron Wyden sent a letter to the Trump administration Friday demanding answers about the fate of Abdulrahman Sameer Noorah, the Saudi man who allegedly ran into and killed a 15-year-old girl and appears to have fled the country with help from the Saudi Arabian government. The letter, sent to Secretary of State Mike Pompeo and Acting Attorney General Matt Whitaker, asked for an investigation of Noorah’s disappearance, The Oregonian reports. Earlier this week, The Oregonian reported that after allegedly hitting and killing Fallon Smart in 2016, Noorah disappeared two weeks before his 2017 trial. Authorities told the paper that Noorah removed his ankle bracelet, and likely obtained a fake passport and fled the country. They also said that they’re fairly certain that Noorah received help from the Saudi government. “These are shocking claims in any event, but with the barbaric murder of U.S. resident Jamal Khashoggi, they suggest a brazen pattern of disregard for the law and abuse of diplomatic privileges,” Wyden wrote, adding that “If they are accurate, they would require significant restrictions on Saudi Arabia’s diplomatic privileges and call into question the future of America’s bilateral relationship with the Saudis.”
