The Trump administration, however, is heavily invested in the long-standing, USA relationship with Riyadh. A senior Turkish official told the Times that they think Khashoggi was killed within two hours of entering the consulate, and that a team of Saudi agents then destroyed his body.
The Trump administration has been criticized for not taking a firmer stance against Saudi Arabia and its leader, Crown Prince Mohammed bin Salman, who has vigorously campaigned to convince other nations of its progressive reforms.
Saudi Arabia, before going silent in recent days, called the allegation it abducted or harmed Khashoggi "baseless". Turkey's President Recep Tayyip Erdogan asked at a press briefing.
Sabah newspaper published the names and years of birth of the 15 Saudis it said arrived at Istanbul's Ataturk airport.
But the Post reported that the Saudis haven't presented any evidence he left the building and say that their video cameras weren't recording at the time.
"I also urge Saudi Arabia, especially King Salman and Crown Prince Mohammed bin Salman, to show the same level of sensitivity and release CCTV footage from the consulate", Cengiz wrote.
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.
Turkish officials claim that Mr Khashoggi was murdered within its walls.
But three USA law enforcement sources said that because Khashoggi is not an American citizen and disappeared outside the country, the Federal Bureau of Investigation has no automatic jurisdiction to get involved in the case and could only become involved if requested by a foreign government such as Turkey.
Mr Erdogan was quoted by Turkish media today as telling journalists flying with him back home from a visit to Hungary that "we can not remain silent to such an incident".
Brett Kavanaugh sworn in as 114th Supreme Court justice
Some 164 people were arrested, most for demonstrating on the Capitol steps, 14 for disrupting the Senate's roll call vote. Kavanaugh was sworn in by Chief Justice John Roberts and retired Justice Anthony Kennedy Saturday evening.
Erdogan said on Thursday, "If a bird flew, if a mosquito appeared, these systems would catch them, and [I believe] they [the Saudis] would have the most advanced of systems".
Earlier Wednesday, Corker, who as the Chairman of the US Senate Foreign Relations Committee has seen US intelligence reports, said that "the likelihood is he was killed on the day he walked into the consulate" and that "there was Saudi involvement" in whatever happened to Khashoggi.
"Well, I think that would be hurting us".
Mr Trump, who took his first overseas trip as USA president to the kingdom and whose son-in-law Jared Kushner has close ties to Prince Mohammed, said he had not yet talked to the Saudis about Khashoggi.
'We're demanding everything, ' Trump said, asked if his team was seeking information from the Saudis - longtime allies who the Trump administration has hugged closely.
Reporters Without Borders also called for an "independent global investigation" to be conducted in a statement issued on Wednesday.
It's unclear what the USA knows about Khashoggi's disappearance, but Trump did cast some doubt on the rumors that Khashoggi was murdered.
"They're spending $110 billion on military equipment and on things that create jobs. for this country. We have a country that's doing probably better economically than it's ever done before". "The intelligence reports are very direct, very short and give further credence to the fact that the focus needs to be on Saudi Arabia right now", Corker said.
Saudi Arabia was last night facing mounting worldwide pressure to come clean over the disappearance of exiled journalist Jamal Khashoggi.
