The conversation took place during a Saturday dinner with heads of state gathered in Paris to mark the World War One Armistice centenary, during which Trump was also seated close to French President Emmanuel Macron and Germany’s Angela Merkel, the official said, Reuters reported.
Khashoggi, an outspoken critic of Saudi Crown Prince Mohammad bin Salman, entered the Saudi consulate in Istanbul on Oct. 2, but never came back.
The Saudi kingdom, after denying the murder for several days, finally admitted that Khashoggi had been murdered in the consulate during an interrogation by rogue operatives that had gone wrong after diplomatic pressure grew tremendously on Riyadh to give an account on the mysterious fate of its national.
However, Saudi Arabia said that it did not know the whereabouts of the body, which is widely believed to have been dismembered.
The Turkish president later said the assassination had been ordered at the "highest levels" of the Saudi government.
