Just days after threatening Saudi Arabia over the disappearance of journalist Jamal Khashoggi - President Trump on Monday announced he was dispatching Mike Pompeo to the kingdom.
(SOUNDBITE) (English) U.S. PRESIDENT DONALD TRUMP, SAYING.
"I just spoke with the king of Saudi Arabia who denies any knowledge of what took place with regard to as he said his Saudi Arabian citizen.
I've asked and he firmly denies that.
I've asked Sec.
Of State Mike Pompeo to immediately get on a plane, go to Saudi Arabia." Khashoggi disappeared after entering the Saudi consulate in Istanbul.
Turkey believes he was murdered - something denied by Saudi Arabia and King Salman who's now ordered an internal probe into the disappearance.
That follows an agreement for a joint Turkish-Saudi team to search the consulate.
The case has provoked an international outcry.
At the weekend Trump threatened "severe punishment" if it turns out Khashoggi was killed.
Saudi Arabia said it would retaliate with even greater action.
Reuters correspondent Katie Paul: (SOUNDBITE) (English) KATIE PAUL, REUTERS SAUDI ARABIA CORRESPONDENT SAYING: "Saudi Arabia was defiant about the case of Jamal Kashoggi.
It says that it will not accept any threats to undermine it or to use any economic sanctions or other forms of political pressure in the case.
So they've staked out a really strong firm position on this case in denying that they're involved in any way, and saying that they will not accept any pressure." Now the countries appear to be working together, with Trump suggesting "rogue killers" may be to blame.
(SOUNDBITE) (English) U.S. PRESIDENT DONALD TRUMP, SAYING: "It sounded to me like maybe these could have been rogue killers.
We're going to try getting to the bottom of it very soon." Meanwhile major business leaders continue to pull out of an influential conference in Riyadh next month dealing a blow to the powerful crown prince's ambitions for economic reform.
Although JP Morgan and Ford haven't officially confirmed why they will not attend it could increase pressure on other U.S. firms. The Saudi riyal is now the weakest it's been since June 2017.
