US Treasury Secretary Seven Mnuchin announced that he would not be attending an investment conference in Saudi Arabia.
Before Trump spoke, the administration announced that Treasury Secretary Steven Mnuchin had pulled out of a major upcoming Saudi investment conference and a US official said Secretary of State Mike Pompeo had warned the Saudi crown prince that his credibility as a future leader is at stake.
The sudden cash windfall raised some eyebrows on Wednesday, given the ongoing investigation into Khashoggi's disappearance, but U.S. officials denied that the swift transfer of cash between Saudi Arabia and the United States had anything to do with Pompeo's visit to Riyadh. The daily reported that in another tape, an unknown individual tells Otaibi: "If you want to live when you return to Saudi Arabia, be quiet!" Citing an anonymous senior Turkish official, ABC News reported on Thursday that Pompeo heard the alleged recording during meetings in Turkey and received a transcript of it.
Earlier this week, Secretary of State Mike Pompeo held talks with both Saudi and Turkish officials to discuss Khashoggi's disappearance.
Mr. Trump said he would wait for the results of three different investigations before drawing conclusions.
The reports alleged his body was dismembered and the killing was carried out by a team of 15 men who arrived the same day from Saudi Arabia, and left soon after.
"Part of our reaction will depend on the Saudi reaction, and whether we sense that they are taking it as seriously as we are taking it".
Previously leaked surveillance footage showed consular vehicles moving from the consulate to the consul general's official residence, some 2 kilometers away, a little under two hours after Khashoggi walked inside.
Turkish officials have said they believe Khashoggi was murdered at the Saudi consulate in Istanbul.
Meanwhile, several high-profile human rights groups have demanded that Turkey ask the United Nations to investigate the possible killing of Mr Khashoggi. "I know what I'm going to do and I'm going to sanction the hell out of Saudi".
"Government welcomes the ongoing diplomatic interaction between the Republic of Turkey and the Kingdom of Saudi Arabia, as well as the investigation which seeks to get to the bottom of this matter".
