The Crown Prince also told associates in August past year that if he failed to persuade Khashoggi to return to Saudi Arabia, "we could possibly lure him outside Saudi Arabia and make arrangements" - a communication the Central Intelligence Agency said "seems to foreshadow the Saudi operation launched against Khashoggi".
The killing of Khashoggi, a Washington Post columnist and a vocal critic of Saudi leadership, has set off a firestorm of demands from USA lawmakers for a strong response to the kingdom as the White House has been reluctant to assign blame to the crown prince.
Secretary of State Mike Pompeo vowed on Saturday that the United States would continue supporting Saudi Arabia's military campaign in Yemen, despite rising outrage over the kingdom. Sources say the Central Intelligence Agency believes the crown prince ordered the killing. "There is no direct reporting connecting the crown prince to the order to murder Jamal Khashoggi", Al Jazeera quoted Pompeo as saying.
Secretary of Defence Jim Mattis said the question of holding the killers responsible and the strategic importance of the US-Saudi relationship were separate issues.
Pompeo, who declined to comment on the CIA's classified assessment, said the United States was working closely with Saudi Arabia on major foreign policy issues, including Afghanistan, and that the kingdom was a vital regional counterweight to Iran.
The Trump administration's reluctance to acknowledge reports from the justice community stands in contrast to calls for a USA response from lawmakers including Senate Majority Leader Mitch McConnell, who demanded action for Khashoggi's death, which he called "completely abhorrent to everything the United States holds dear and stands for".
