Unlike Trump, Obama had few kind words for the Saudi government, often attacking its history of human rights abuses and its role in funding jihadist terrorism.
President Trump also discussed the disappearance with reporters at the White House Wednesday. "I don't like hearing about it", Trump told reporters at the White House on Monday. He served as an adviser to senior Saudi officials.
The administration has expressed concern but has refused to even to entertain questions about what the consequences would be if Turkish allegations turn out to be true - that the 59-year-old journalist was killed inside the Saudi consulate in Istanbul after entering it on October 2 to get routine paperwork for his marriage while his Turkish fiancé waited outside.
Media captionCCTV footage shows missing Saudi journalist Jamal Khashoggi entering the Saudi consulate in Istanbul. According to the New York Times, officials in Istanbul believe he was killed on orders from the royal court of Saudi Arabia.
"We are very disappointed to see what's going on. And the reports that a Saudi Arabian journalist may have been tragically murdered in Turkey should be deeply concerning to everyone who cherishes a freedom of the press and human rights across the globe". "We don't know what happened yet".
'Monstrous' Hurricane Michael forecast to hit Gulf Coast as a major hurricane
ET Monday, Tropical Storm Michael was centered about 90 miles east of Cozumel, Mexico, the National Hurricane Center said . Michael is the 13th named storm of the 2018 hurricane season, according to hurricane center spokesman Dennis Feltgen.
In government-aligned newspapers and on social media, many Saudis have advanced a narrative that the accusations are part of an insidious campaign to smear their country - pointing fingers at Turkey, Qatar and the Muslim Brotherhood, an Islamist group that Saudi Arabia and some of its Arab allies consider a terrorist organisation. "If Donald Trump is not getting in touch with the king of Saudi Arabia, he is being derelict in his duty....(Trump's) statements, so far, have been completely inadequate".
It was reported on Tuesday that the six cars that left the consulate, several hours after Khashoggi had entered, stopped for several hours at the nearby Saudi consul general's residence, a site that has now become a focal point of the investigation into what happened to him.
Turkish media Wednesday showed what it said was a team of the 15 Saudis arriving at the Istanbul airport on the same day Khashoggi went missing.
Corker said that he had warned the kingdom that its political support in the Senate is "the lowest ever" and that if Saudi officials are responsible for Kashoggi's disappearance, "this would drop it off a cliff".
A human rights activist holds picture of Saudi journalist Jamal Khashoggi during a protest outside the Saudi Consulate in Istanbul, Turkey October 9, 2018. An hour and 54 minutes later, according to the time stamp, a black Mercedes Vito with diplomatic license plates, which resembled a van parked outside of the consulate when the writer walked in, drives some 2 kilometers (1.2 miles) to the consul's home, where it parks inside a garage. The 15 men reportedly left Turkey that same evening. A search would be an extraordinary development, as embassies and consulates under the Vienna Convention are technically foreign soil and must be protected by host nations.
