In 2019, U.S. federal law enforcement officials launched an investigation into cases involving the disappearance of Saudi Arabian students from Oregon and other parts of the country, while they faced charges in the U.S. Amidst the investigation, it has been speculated that the Saudi government helped the students in escaping from the U.S. In October 2019, the U.S. Senate passed a bill by Sen. Ron Wyden of Oregon, requiring the FBI to declassify any information regarding Saudi Arabia's possible role. Oregon officials demand extradition of these suspects by Saudi Arabia since they were involved in violent crimes causing bodily harm and death.
