The mysterious circumstances around Khashoggi, a onetime Saudi insider turned critic who lived in the United States and contributed to The Washington Post, have badly dented the worldwide image of Crown Prince Mohammed bin Salman who until recently was hailed in the West as a reformist saviour.
US Secretary of State Mike Pompeo visited Saudi Arabia on Tuesday for talks with King Salman, Crown Prince Mohammed bin Salman, and Foreign Minister Adel al-Jubeir.
He was part of MBS' entourage when the crown prince made an extensive USA tour earlier this year. Lindsey Graham of SC, turning to speak to the camera. The journalist is a Saudi citizen and used to be an insider with the royal family.
President Donald Trump on Monday talked to the Saudi King, during which the latter flatly denied having any knowledge of the missing journalist.
"The Saudi government can no longer remain silent, and it is essential that our own government and others push harder for the truth", Ryan added.
The issue will be to what extent the West believes the responsibility lies with MBS for Khashoggi. The official, who spoke on condition of anonymity in line with government regulations, gave no timeline for the search.
Mr Khashoggi appeared regularly on Arab talk shows and moved to Washington previous year.
The official did not say when the search of the consul's home would take place. Saudi Arabia did not immediately acknowledge he had left or offer a reason for his departure.
He said it was too early to say whether he endorsed other countries' actions. Under the Vienna Convention, diplomatic posts are technically foreign soil that must be protected and respected by host countries. He was last seen entering the Saudi consulate in Istanbul where he went to receive papers he needed to remarry. CCTV footage showed vehicles moving from the consulate building to the nearby Saudi consul general's residence on October 2.More news: Sen. Elizabeth Warren's DNA claim inflames some Native Americans
Erdogan told journalists Tuesday that police sought traces of "toxic" materials and suggested parts of the consulate had been recently painted, without elaborating. The former Central Intelligence Agency chief didn't make any remarks to the media.
The secretary of state was dispatched to Riyadh on Monday after Mr Trump spoke to King Salman on the phone.
But the heir apparent "pledged that the work of the Saudi public prosecutor will produce a full and complete conclusion with full transparency for the world to see", Pompeo said.
"We are strong and old allies", the prince told Pompeo.
Pompeo arrived at a royal palace in Riyadh on Tuesday.
The kingdom also denied an assertion by France that it held Lebanese Prime Minister Saad al Hariri captive in November 2017.
A bipartisan letter of support in favour of applying the Magnitsky Act against the Saudi authorities in retaliation for Mr. Khashoggi's death, and the relentless questioning about what Mr. Trump was going to do to pursue the case, were unnecessary diversions. So if the United States sanctions Saudi Arabia and the Saudis slash oil production in retaliation, that could mean a big spike in global oil prices. "It sounded to me like maybe these could have been rogue killers".
Trump, who has had business ties with Saudis, has alternated between vows to punish any Saudis proven to be involved, and reticence over imposing sanctions, as some members of Congress have demanded.
The source said Saudi Arabia must make "a genuine contribution" to the investigation of Khashoggi's disappearance in Istanbul.
Pompeo next travels to Turkey to meet with officials there.
