Rep. Joaquin Castro, D-Texas, called Friday for an investigation into Jared Kushner’s handling of classified information, while also walking back an apparent charge that the president’s son-in-law gave Saudi Arabia intelligence that led to the presumed murder of journalist Jamal Khashoggi.

“To be clear, I did not intend to accuse Jared Kushner of orchestrating the killing of Jamal Khashoggi,” Castro said in a statement to the Washington Examiner. “But based on several press reports, the close relationship between Kushner and [Saudi Crown Prince] Mohammed bin Salman is a source of concern for the U.S. intelligence community and those of us who want a transparent American foreign policy.”

Castro, a member of the House intelligence panel, alleged earlier Friday that Kushner may have given information to Saudi Arabia that led the crown prince to order the murder of Washington Post columnist Jamal Khashoggi. Calling it the “most disturbing” part of the Khashoggi crisis, he told CNN that Congress needs to investigate Kushner’s conversations with the Saudi royal.

“Jared Kushner may have, with U.S. intelligence, delivered a hit list, an enemies list, to the crown prince, to MBS, in Saudi Arabia,” Castro said on CNN. “The prince may have acted on that, and one of the people he took action against is Mr. Khashoggi... I’ve seen reporting to that effect.”

The Republican side of the House Intelligence Committee was dismissive. “That is utterly ridiculous,” a GOP aide said in response.

But Castro’s team, while tempering its claim that the White House played a role in the events that led to Khashoggi’s death, also drew attention to a report from The Intercept regarding Kushner’s travel to Saudi Arabia last year that said that the crown prince had claimed that Kushner had discussed the names of Saudis disloyal to him.

Castro said that “the president and his family’s business enterprises and the possibility that they profit from these foreign entities” are reasons for doubt about Kushner’s discussions with the crown prince.

“For these reasons, Congress should open an investigation to see whether Jared or any other Administration official shared any U.S. intelligence with the Saudis that led to any political persecution, including the killing of Jamal Khashoggi,” he told the Washington Examiner.

Khashoggi, as a Washington Post columnist, was a prominent critic of the Saudi Arabian government.
