Trump, who took his first overseas trip as US president to the kingdom and whose son-in-law Jared Kushner has close ties to Prince Mohammed, said Tuesday he had not yet talked to the Saudis about Khashoggi, "but I will be at some point", without elaborating.
Stakes are high in the relationship between the United States and Saudi Arabia, and Mr Trump is one of many Western leaders to stand by the kingdom's young leader Mohammed bin Salman. Although his opinions had angered certain people, he said, the tensions between himself and Saudi Arabia did not amount to hate, grudges or threats.
Spokeswoman Sarah Sanders said the U.S.is continuing to monitor the unfolding investigation in Istanbul, but offered no information about what the crown prince told the USA officials regarding Khashoggi's disappearance.
A US intelligence source told the New York Times that USA intelligence had intercepted communications of Saudi agents discussing a plot to either capture or kill Khashoggi.
"It's a very sad situation, it's a very bad situation, Trump said".
Iran has warned that if it can not sell its oil due to U.S. pressure, then no other regional country will be allowed to do so either, threatening to block the Strait of Hormuz.
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.
In Istanbul, Khashoggi met his fiancee, Hatice Cengiz, a PhD student who had met Khashoggi at a seminar.
Jamal Khashoggi: Turkey to search Saudi consulate
Investigators said a 15-person team arrived at the consulate on Tuesday, returning to Riyadh the same day. On Monday President Trump said that he was "concerned" about reports on Khashoggi's disappearance.
The Saudi-born Washington Post columnist Jamal Khashoggi has been missing for over a week-with reports strongly indicating he was murdered last week by a "hit team" sent by the government of Saudi Arabia while inside the country's consulate in Istanbul, Turkey-but critics from across the political spectrum say the Trump administration still has not used its close ties to the ruling Royal Family, and especially with Crown Prince Mohammad bin Sulman (MbS), to get anywhere nearer the truth of what happened to Khashoggi or hold the Saudis feet to the fire over the possible assassination of a US resident and journalist.
While the Saudi authorities have said Khashoggi left the building shortly after he arrived, Turkish sources told Middle East Eye he was killed inside the consulate.
When I asked him why he made a decision to live in the United States, he said America was the world's most powerful country, where one could feel the political pulse of the planet. He had apparently drawn the wrath of the Saudi government, which has become an ever-closer US ally under President Donald Trump.
He told conservative talk show host Hugh Hewitt that Khashoggi's disappearance is "a great concern for the United States of America". Nauert said Secretary of State Mike Pompeo and other USA diplomats have been engaged on the issue and that Trump himself - he said Tuesday he "knows nothing" about what happened to Khashoggi - intends to speak to the Saudis. Frankly, because it's a reporter, you could say in many respects, it brings it to a level.
The planes belonged to a company based in Saudi Arabia which has links to the state.
Turkey's public broadcaster TRT World has obtained video footage which shows the Saudi government critic Jamal Khashoggi entering the Saudi consulate on October 2nd. "But I don't want to rush to judgment".
Saudi Arabia remained silent at the accusation as the images were seen around the world, raising pressure on the kingdom to explain what happened to the writer, a critic of Saudi Crown Prince Mohammed bin Salman.
Turkish media close to the president published images on Wednesday of what it described as a 15-member "assassination squad" allegedly sent to target Saudi journalist Jamal Khashoggi. Khashoggi has been a contributing writer for the Post.
