>> Just days after threatening Saudi Arabia over the disappearance of Washington Post columnist Jamal Khashoggi, President Trump on Monday floated an alternate explanation.>> It sounded to me like maybe these could have been rogue killers. Who knows, we're gonna try getting to the bottom of it very soon.
>> Khashoggi disappeared after entering the Saudi consulate in Istanbul earlier this month. Turkey believes he was murdered. A Turkish security source had previously told Reuters that a group of 15 Saudi nationals had arrived in Istanbul in two planes and entered the consulate on the same day Khashoggi was there, and later left the country.
King Salman denied any involvement, and ordered an internal probe into the disappearance. That follows an agreement for a joint Turkish Saudi team to search the consulate. Over the weekend, Trump threatened a severe punishment if it turns out Khashoggi was killed, prompting Saudi Arabia to say it would retaliate with even greater action.
Reuters correspondent, Katie Paul.>> Saudi Arabia was defiant about the case of Jamal Khashoggi. It says that it will not accept any threats to undermine it or to use any economic sanctions or other forms of political pressure over the case. So they've staked out a really strong firm position on this case in denying that they're involved in any way.
>> Now the countries appear to be working together, with Trump dispatching his Secretary of State to the kingdom.>> 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 citizens. I've asked, and he firmly denied that.
I've asked Secretary of State, Mike Pompeo, to immediately get on a plane, go to Saudi Arabia.>> Meanwhile major business leaders continue to pull out of an influential conference in Riyadh next month, feeling a blow to the powerful crowned prince's ambition for economic reform. JP Morgan CEO Jamie Dimon pulled out, and a source tells Reuters that Blackstone CEO Stephen Schwarzman and Blackrock Chief Executive Larry Fink are out as well.
