A source familiar with the Turkish investigation has told CNN that Saudi intelligence officer and former diplomat Maher Abdulaziz Mutreb played a "pivotal role" in the apparent assassination of Khashoggi.
While Turkish officials have accused Saudi Arabia of the murder in Istanbul of Khashoggi, a US-based writer who has been critical of Saudi leaders, Trump has cautioned against a rush to judgment against an important Mideast ally. Whether any of the pushback and outrage will lead to any rethinking of the U.Sadministration's's approach to Saudi Arabia, however, remains to be seen.

Mr Khashoggi went to the consulate seeking documents for his planned marriage to his Turkish fiancee, who was waiting outside and was never seen again.
Conservative online broadcast CR-TV said Tuesday that Khashoggi was a "longtime friend" of terrorists, outright claiming that Trump was being targetted by an "insane" media conspiracy to smear him. The prince is next in line for the throne held by his aged father King Salman.
