Treasury Secretary Steven Mnuchin on Thursday said he would not attend an investment conference in Saudi Arabia following the disappearance and apparent killing of journalist Jamal Khashoggi.

"Just met with @realDonaldTrump and @SecPompeo and we have decided, I will not be participating in the Future Investment Initiative summit in Saudi Arabia," Mnuchin tweeted.

The Treasury Secretary initially maintained his intention to attend the Future investment Initiative in Riyadh, Saudi Arabia, despite the outcry over Khashoggi's disappearance.
