(ROUGH CUT - NO REPORTER NARRATION) U.S. President Donald Trump on Saturday (November 17) called a CIA assessment blaming Saudi Crown Prince Mohammed bin Salman for the killing of Saudi journalist Jamal Khashoggi "very premature" and said he will receive a complete report on the case on Tuesday.

Trump, on a trip to California, said the killing "should never have happened." The report on Tuesday will explain who the U.S. government believes killed Khashoggi and what the overall impact of his murder is, Trump said.

It was unclear who is producing the report.

Trump also said the CIA finding that bin Salman was responsible for the killing was "possible." Trump made the remarks hours after the State Department said the government was still working on determining responsibility for the death of Khashoggi, a U.S.-based Washington Post columnist.

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.
