According to a New York Times report the Saudi royal court will soon put out a narrative that an official within the kingdom's intelligence services - who happens to be a friend of Prince Mohammed - carried out Khashoggi's killing.
Her spokesman Rupert Colville said: "We hope the lifting of immunity is absolute so they can investigate, in the consulate, the (consular) residence premise, the vehicles shown on TV footage".
Earlier, a joint Saudi-Turkish team entered the Saudi Consulate in Istanbul to search it.
A third source, also close to the Saudi government, told Atwood that the Saudis would claim the operation was planned and executed by a general close to the crown prince, and that MBS never authorized Khashoggi's murder.
Butler, who planned to promote his new movie "Hunter Killer", about a standoff between a US submarine and Russian forces, said neither the USA government nor the Navy asked him not to visit the country.
In an earlier statement, President Tayyip Erdogan said Turkish authorities will continue to seek the truth.
Pompeo said the leadership "strongly denied any knowledge" of what happened in the consulate. "But that can't happen until there is a full accounting of Khashoggi's disappearance, and until the United States receives assurances that Saudi Arabia will be a much more responsible ally".
Khashoggi, a columnist for The Washington Post, disappeared after entering the Saudi consulate in Turkey two weeks ago. Pompeo met later in the day with Foreign Minister Adel al-Jubeir and Crown Prince Mohammed bin Salman, dining with the prince in the evening.
Meanwhile, the consul general himself, Mohammed Otaibi, left Turkey on Tuesday, the semiofficial Anadolu news agency said.
The UN human rights chief called Tuesday for the lifting of the immunity of officials who might be involved in Khashoggi's disappearance.
The US Secretary of State Mike Pompeo will visit Turkey, the Turkish media reported October 16.
Turkish prosecutors have also reiterated that they have the "evidence of killing" at the Saudi consulate.
This comes after it was reported a large truck was seen leaving the consulate and parking at a Saudi official's home just hours after Khashoggi's disappearance.
Pompeo addressed reporters Thursday after briefing President Trump at the White House on his talks with leaders in Saudi Arabia and Turkey.
A report by CNN quoted two sources as saying that the Saudi side is preparing a report to acknowledge that the interrogation of Khashoggi had been meant to abduct him from Turkey, but went wrong and lead to his death.
Khashoggi's disappearance has caused USA -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. Trump himself said without offering evidence that the slaying could have been carried out by "rogue killers", offering the USA -allied kingdom a possible path out of a global diplomatic firestorm. But Khashoggi's disappearance has led several business leaders and media outlets to back out of the upcoming investment conference in Riyadh, called the Future Investment Initiative.
Turkish police officers arrive at the Saudi Arabia's Consulate in Istanbul, Oct. 15, 2018. Turkish officials provided CNN with passport scans of seven men they suspect were part of the group. This was another diplomatic slapped on Saudi Arabia's by allowing it's sacred building to be accessed in relating to crime!
"There are other countries we could sell that to", Rubio told CNN.
Saudi Arabia on Sunday warned against any threats to exert economic sanctions or political pressure on the kingdom, saying it will respond with greater action given the kingdom's outsized role in the global economy.
