News outlets and journalists are withdrawing support for a high-profile annual conference scheduled to take place in Saudi Arabia after Washington Post columnist Jamal Khashoggi went missing amid reports he may have been lured to the country and killed at the direction of the Saudi government.

CNBC correspondent Andrew Ross Sorkin tweeted Thursday that he would skip the Future Investment Initiative event, and Los Angeles Times publisher Patrick Soon-Shiong said he would do the same, according to CNBC.

"I’m terribly distressed by the disappearance of journalist Jamal Khashoggi and reports of his murder," Sorkin said in his tweet. "I will no longer be participating in the Future Investment Initiative in Riyadh."

The New York Times reportedly set as a sponsor the event, scheduled for late October, but has withdrawn its support.

The Financial Times said in a statement it would also no longer participate "while the disappearance of journalist Jamal Khashoggi remains unexplained."

CNN has also withdrawn its support.

Kashoggi went missing on Oct. 2 after he entered a Saudi consulate in Turkey, reportedly to obtain paperwork that would allow him to re-marry. He never left the consulate and is widely believed to have been killed at the direction of the Saudi government, which Kashoggi has been critical of in his journalism.
