Secretary of State Mike Pompeo has arrived in Saudi Arabia after being dispatched by President Trump to meet with members of the royal court amid growing international tension over the disappearance of prominent Saudi journalist Jamal Khashoggi.

Pompeo met on Tuesday with King Salman bin Abdul-Aziz Al Saud in the Saudi capital and financial hub of Riyadh.

"Thank you for accepting my visit on behalf of President Trump," Pompeo said on meeting the king. Details of the meeting were not immediately made public.

Pompeo will meet later Tuesday with Foreign Minister Adel al-Jubeir and Crown Prince Mohammed bin Salman, dining with the prince in the evening.

Khashoggi, an outspoken critic of Saudi policy, has not been seen since he entered the Saudi Consulate in Istanbul two weeks ago. The Turkish government alleges that he was murdered by Saudi agents — a charge the Saudis have denied.

However, The New York Times and CNN report that the kingdom is preparing to acknowledge in an official report that Khashoggi died during a botched interrogation. Both the Times and CNN caution that the details of the Saudi's report, based on tips from anonymous sources familiar with the Saudi investigation, could change.

A Turkish paper has alleged that a team of 15 Saudi men flew into Istanbul on Oct. 2, hours before Khashoggi was last seen entering the consulate, describing the men as an assassination squad.

On Tuesday, Turkish investigators searched the consulate building. Reuters reports the team conducted a nine-hour search of the premises, and left with evidence, including soil samples.

Trump told reporters on Monday that he spoke with the Saudi king, who has "firmly denied" any knowledge of Khashoggi's whereabouts.

"I don't want to get into his mind — but it sounded to me like maybe these could have been rogue killers," the president said. "Who knows? We're going to try getting to the bottom of it very soon. But his was a flat denial."

The remarks were a departure from what the president said during an interview with CBS' 60 Minutes last week, when he threatened the kingdom with "severe punishment" if it turned out that Khashoggi had been murdered.

On Monday, Trump tweeted that he was sending Pompeo to meet with King Salman in an effort to "find an answer."

Khashoggi's disappearance has caused U.S.-based companies, including Uber, JPMorgan Chase and Google — which planned this year to build five innovation hubs in Saudi Arabia — to pull out of a high-profile investment summit in Riyadh scheduled for later this month. The cancellations are a blow to the government, which has tried to market itself as an open, innovative place to invest and do business.

On Friday, Treasury Secretary Steve Mnuchin told reporters he still plans to attend the Riyadh investment summit; however, the president said Monday it was possible the U.S. would not attend, but that no decision had been as yet.
