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.”

“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.
