Trump calls CIA assessment of Khashoggi murder premature but possible

"Recent reports indicating that the U.S. government has made a final conclusion are inaccurate," State Department spokeswoman Heather Nauert said in a statement. "There remain numerous unanswered questions with respect to the murder of Mr. Khashoggi."

Nauert said the State Department will continue to seek facts and work with other countries to hold those involved in the journalist's killing accountable "while maintaining the important strategic relationship between the United States and Saudi Arabia."

Trump discussed the CIA assessment by phone with the agency's director, Gina Haspel, and Secretary of State Mike Pompeo while flying to California on Saturday, White House spokeswoman Sarah Huckabee Sanders told reporters.

The CIA had briefed other parts of the U.S. government, including Congress, on its assessment, sources told Reuters on Friday, a development that complicates Trump's efforts to preserve ties with the key U.S. ally.

A source familiar with the CIA's assessment said it was based largely on circumstantial evidence relating to the prince's central role in running the Saudi government.

The CIA's finding is the most definitive U.S. assessment to date tying Saudi Arabia's de facto ruler directly to the killing and contradicts Saudi government assertions that Prince Mohammed was not involved.

Khashoggi, a critic of the crown prince, was killed in October at the Saudi consulate in Istanbul when he went there to pick up documents he needed for his planned marriage.

As lawmakers push legislation to punish Saudi Arabia for the killing, both Republican and Democratic senators on Saturday urged Trump to be tough on the crown prince, with whom he has cultivated a deep personal relationship.

"Everything points to the Crown Prince of Saudi Arabia, MbS, ordering @washingtonpost journalist Jamal #Khashoggi's killing. The Trump administration should make a credible determination of responsibility before MbS executes the men who apparently carried out his orders," tweeted Senator Bob Corker, chairman of the Senate Foreign Relations Committee, on Saturday.

Trump and top administration officials have said Saudi Arabia should be held to account for any involvement in Khashoggi's death and have imposed sanctions on 17 Saudis for their role in the killing.

But they have also stressed the importance of Washington's ties with Riyadh, one of the biggest clients of the U.S. defense industry. Trump wants to preserve the Saudi arms deals, despite growing opposition in Congress.

"They have been a truly spectacular ally in terms of jobs and economic development," Trump said. "As president, I have to take a lot of things into consideration."

Marine General Joseph Dunford, chairman of the Joint Chiefs of Staff, noted on Saturday that the kingdom plays a key military role for the United States in the Middle East.

"Saudi Arabia has been an important partner to regional security in the past. I expect they will be in the future," he said at a security forum in Halifax, adding Middle Eastern allies including Saudi Arabia are "a stabilizing force in the region."

On Thursday, Saudi Arabia's public prosecutor said he was seeking the death penalty for five suspects charged in the killing of Khashoggi.

The prosecutor, Shaalan al-Shaalan, told reporters the crown prince knew nothing of the operation, in which Khashoggi's body was dismembered and removed from the consulate. Saudi officials have said a team of 15 Saudi nationals were sent to confront Khashoggi and he was accidentally killed in a chokehold by men who were trying to force him to return to the kingdom.

Lawmakers critical of Saudi Arabia for Khashoggi's killing and its role in Yemen's civil war are ramping up their efforts to clamp down on the country.
