US President Donald Trump has said the CIA did not conclude that Saudi Crown Prince Mohammed bin Salman ordered the murder of journalist Jamal Khashoggi.
Khashoggi was killed on 2 October in the Saudi consulate in Istanbul.
Officials told US media such an operation would have needed the prince's approval. But Saudi Arabia maintains it was a "rogue operation".
"They didn't conclude," Mr Trump said when asked about the CIA's reported evaluation by reporters in Florida.
His comments on Thursday came as the Saudi crown prince began a regional tour of the Middle East, starting with the United Arab Emirates - his first official trip abroad since Khashoggi was killed.
The Crown Prince of Abu Dhabi, Mohammed bin Zayed, tweeted to say the UAE "will always be a loving and supportive home for our brothers in Saudi Arabia".
The Saudi crown prince is also expected to participate in a G20 meeting of world leaders in Buenos Aires at the end of the month that will be attended by leaders from the US, Turkey and a number of European countries.
Meanwhile, France has announced that it is imposing sanctions on 18 Saudi nationals - the same individuals targeted with sanctions by the US, UK and Germany - allegedly linked to the Khashoggi murder.
Their list of individuals does not include the crown prince, a spokesperson for the French ministry of foreign affairs said.
