The fiancée of slain Saudi journalist Jamal Khashoggi on Wednesday criticized the Trump administration's response to his killing.

Khashoggi “had always championed the U.S.” as “the place you went to challenge the status quo and speak truth to power,” Hatice Cengiz said in an interview with The Washington Post. “Jamal would have been most disappointed of all to see the U.S. response.”
