His meeting with Prince Khalid bin Salman took place in Washington, DC in early 2018 or late 2017 as the Washington Post columnist visited the embassy on consular matter, three people told NBC News.
A friend of the late journalist told the channel Khashoggi had described both the prince and their conversation as "nice." He did not give any details.
The meeting came amid continued attempts by the royal court to bring him back. Prince Khalid had reportedly been contacting Khashoggi for at least a year before their Washington meeting.
Khashoggi, a critic of the Saudi government residing in the United States, was killed inside the Saudi consulate in Istanbul where he went to get papers he needed to marry his Turkish fiancee.
