Asked by a reporter whether he thought Saudi Arabia's explanation for Khashoggi's death was credible, Trump said, "I do". Two weeks after Khashoggi's disappearance, he posted a tweet apparently responding to widespread accusations that he was the mastermind of Khashoggi's killing.
"The Turks have been talking more to the media than they have us", Corker said of the North Atlantic Treaty Organisation ally. "I am going to go there and meet with my counterparts and continue to focus on what's in the Treasury's domain, as it relates to this issue".
The evolving explanation comes 19 days after Khashoggi, a Saudi journalist who had been critical of his country's current government, disappeared on October 2 after going into the Saudi consulate in Istanbul.
The remarks came after Turkish President Tayyip Erdogan said Sunday that he will reveal more about the investigation into Khashoggi's killing on Tuesday.
Saudi Arabia finally admitted early Saturday that Khashoggi had died inside the consulate in what it described as a "brawl". The kingdom also said that 18 suspects were in custody and that intelligence officials had been fired.
Saudi Arabia is the UK's key ally in the region and a significant trading partner - with Britain also rolling out the red carpet for Crown Prince Mohammed bin Salman.
"People fear them. You challenge them, you might end up in prison, and that has happened", he said. "But I want to get to the answer". "That is not the focus of my trip".
Some governments and prominent executives have said they would pull out of a forthcoming investment conference in Saudi Arabia.
But one suspect identified by Turkey was said to be a frequent companion of the young heir to the throne, three others were linked to his security detail and a fifth is a high-level forensic specialist, according to The New York Times.
On October 4, Saudi government officials said he had left the consulate through a back door.
"Saudi Arabia has been a great ally".
The Saudi stock market is down about 4% since Khashoggi's disappearance.
McKinsey said in a statement that it was "horrified" by the possibility its report was used to target individuals and that it was not prepared for any government entity.
Mr Al-Jubeir echoed President Donald Trump's warnings against rushing to judgment against Saudi leaders, saying "there is the presumption of innocence until proven guilty", and that some have "turned that upside down". But the prince himself, protected by his 82-year-old father, King Salman, has been tapped to lead a panel to reform the kingdom's intelligence services, a sign he will remain next in line to the throne.
