The fiancee of missing Saudi journalist Jamal Khashoggi on Tuesday asked President Donald Trump to help uncover what happened to the Riyadh critic who she said had "been fighting for his principles".
Hatice Cengiz made the appeal in an opinion piece for The Washington Post newspaper, where Khashoggi was a columnist and an outspoken critic of some of Riyadh's policies.
A veteran journalist, Khashoggi disappeared on October 2 after entering Saudi Arabia's consulate in Istanbul to arrange paperwork for his wedding to Cengiz, a Turk.
