Saudi Crown Prince Mohammed bin Salman – the presumptive king and one of Trump’s closest allies in the region – is under growing pressure to explain the disappearance of Khashoggi, who U.S. intelligence officials believe was killed and dismembered by a Saudi “murder team” inside the Saudi consulate in Turkey on Oct. 2. Mnuchin said in his tweet, “I will not be participating in the Future Investment Initiative summit in Saudi Araba.”

His announcement comes after Pompeo told reporters at the White House that the administration would await the outcome of investigations by Saudi Arabia and Turkey into the disappearance of journalist Jamal Khashoggi before deciding how the U.S. will respond. The veteran Saudi journalist who has been critical of the government has gone missing after visiting the kingdom's consulate in Istanbul on September 2, 2018, the Washington Post reported.
