Interested in Jamal Khashoggi?
It comes as Saudi Arabia has denied involvement in his disappearance.
However, the U.S. president has repeatedly made clear that he will not risk billions of dollars in deals to sell weapons to the kingdom, which is a strategic ally in the tinder box Middle East.
"The Saudis are funneling money to him", said former federal ethics chief Walter Shaub, who is advising a watchdog group suing the president for foreign government ties to his business.
President Trump raised the possibility on Monday that missing and presumed-dead journalist Jamal Khashoggi may have been murdered by "rogue killers" from Saudi Arabia, a theory he floated to reporters after a phone call with Saudi King Salman.
Turkish authorities said they believed that 15 Saudi men who arrived in Istanbul on October 2 were connected to the case.
Trump dispatched his Secretary of State Mike Pompeo to the kingdom on Monday to find out "first-hand what happened, what they know, what's going on".
"The denial was very, very strong", he told reporters at the White House.
But Trump, who has frequently boasted about his business ties with the kingdom, suggested during the CBS interview that ending US arms sales to Saudi Arabia would not be an option, saying, "I don't want to hurt jobs". "We're going to try getting to the bottom of it very soon, but his was a flat denial". Turkish officials say they believe Saudi agents killed and dismembered Khashoggi and say Turkey has audio and video recordings of it.
Saudi officials have called all the allegations "baseless", but have offered no evidence the journalist left the consulate.
The US State Department also has urged a thorough investigation into the disappearance. American lawmakers have threatened tough punitive action against the Saudis, and Germany, France and Britain have jointly called for a "credible investigation" into Khashoggi's disappearance.
Prince Mohammed, 33, a son of King Salman, consolidated his control in June 2017 when he was named Crown Prince to replace his cousin, Mohammed Nayef, who was sacked. CNN reports saw investigators, including forensics officers, enter the building, where they stayed for nine hours before leaving.
Trump had used a similar formulation of language when his nomination of Brett Kavanuagh to the U.S. Supreme Court ran into trouble in the Senate after several women came forward to accuse Kavanaugh of sexual misconduct. USA intelligence officials have reported they are certain the interference took place in an effort to hurt Hillary Clinton's campaign.
When asked about whether the United States will take the arms deal off the table with Saudi Arabia, Trump said "I'm not taking anything off the table".
On Sunday, Saudi Arabia warned that if it "receives any action, it will respond with greater action".
The other source said the report would likely conclude that the operation was carried out without clearance and that those involved will be held responsible, the cable news outlet said.
"The world is watching, the world is talking". "This, I think, depends on the crown prince".
