Sen. Bob Corker, the chairman of the Foreign Relations Committee, said in a tweet Monday that he had spoken with the Saudi ambassador.
In a fresh clue, a pro-government Turkish daily on Wednesday published preliminary evidence from investigators it said identified a 15-member Saudi intelligence team involved in Khashoggi's unexplained disappearance on October 2. "If this happened, if they murdered this journalist who works for The Washington Post in a consulate in Istanbul, Turkey, that's a game-changer for me". Cengiz wrote in the Washington Post today that the couple planned to split their time between D.C. and Istanbul.
On Wednesday, Turkish media outlets published CCTV footage, which they say shows evidence of a plot linked to Mr Khashoggi's disappearance.
Interior Minister Prince Abdulaziz bin Saud bin Naif bin Abdulaziz stressed that what has been circulating about orders to kill him are lies and baseless allegations against the government of the Kingdom, which is committed to its principles, rules, and traditions and is in compliance with worldwide laws and conventions, ' the statement went on.
A critic of Crown Prince Mohammed bin Salman, Mr Khashoggi was living in self-imposed exile in the United States and writing opinion pieces for the Washington Post before his disappearance. Saudi Arabia has denied the allegations, insisting he left the consulate on his own.
Mr Cavusoglu has urged the kingdom to allow Turkish officials to enter the consulate.
The woman, who is a Turkish citizen, called police when Khashoggi did not emerge at 5 p.m., after the consulate had officially closed.
The list also includes the name Mohammad Saad al-Zahrani.
Further reports said that a group of 15 Saudis entered the consulate on the same day as Khashoggi and soon left the country, and that Khashoggi had been dismembered and smuggled out of Turkey in small boxes.
News channel 24 aired the video, suggesting that Khashoggi was inside of the black Mercedes Vito, which resembled one parked outside of the consulate when the writer walked in on October 2.
The Hurriyet newspaper and other media alleged that the consulate's 28 local staff were given the day off because a "diplomats' meeting" would be held there. The reports did not cite a source and there was no official confirmation of the claim.
"What you do have evidence of is that the Saudis have been bombing civilians in Yemen for over a year now", he said.

The official said the camp had been destroyed. '(A recovery team) could see the bodies of the climbers scattered near the camp'. Expedition organisers raised the alarm after losing contact with the group, who set off on 7 October, for almost 24 hours.
Cengiz and Khashoggi met at a conference in May, where they soon "became emotionally involved and made a decision to marry", she said. "It is not possible for us to remain silent regarding such an occurrence, because it is not a common occurrence", he said.
Embassies and consulates under the Vienna Convention are technically foreign soil and must be protected by host nations.
Turkish officials say he was killed by Saudi agents during the visit.
'I would certainly concerned, ' he said. "And they should be cooperating with us".
"At this time I implore President Trump and First Lady Melania Trump to shed light on Jamal's disappearance", wrote Cengzi.
The Turkish president's latest comments come just hours after US President Donald Trump vowed to "get to the bottom" of Mr Khashoggi's case. A third appeared to be a special forces soldier who worked as a bodyguard to Mohammed bin Salman, the Crown Prince of Saudi Arabia.
Secretary of State Mike Pompeo then had a follow-up call with the crown prince to reiterate the USA request for information and a thorough, transparent investigation.
About two hours later Aksam showed two vehicles, one of them a black Mercedes Vito van with tinted windows and diplomatic plates, leaving the consulate and entering the auto park of the residence shortly afterwards.
Mr Trump said he would probably speak to Saudi Arabia's King Salman over the weekend "because I think it's appropriate for me to ask him what's going on". "We can't let this happen". We have a country that's probably doing better economically than its ever done before.
He continued: "Part of that is what we're doing with our defense systems and everybody's wanting them. I don't trust him for a minute'".
Reports say that the U.S. and Britain are considering boycotting a major worldwide conference in Saudi Arabia after the disappearance. It relies on Saudi support for its Middle East effort to counter Iranian influence and fight extremism. His Turkish fiancee waited outside.
