"The leaders and presidents that belong to Trump's sphere are the ugly sorts of tyrannies in the world, like Abdel Fattah al-Sisi, [Abu Dhabi crown prince] Mohammed Bin Zayed and Mohammed Bin Salman", he told MEE.
"Our expectation is that in making your determination you will consider any relevant information, including with respect to the highest ranking officials in the Government of Saudi Arabia", the letter said. "That's a bad situation".
Kaye said he did not have "any particular plan" about what the global investigation would look like, but that "multiple models" - such as a United Nations -mandated probe - exist. Bob Corker, who as chairman of the Senate Foreign Relations Committee has reviewed USA intelligence on the case, said it was likely that Khashoggi was killed the day he walked into the consulate.
"When I hear of the arrest of a friend who did nothing that (deserved being) arrested, it makes me feel I shouldn't go", he told the BBC.
Social media sleuths identified another man from the squad as a senior crimes scene investigator in Saudi Arabia.
Sabah newspaper, which is close to Turkish President Recep Tayyip Erdogan, on Wednesday revealed the identities of what it called a "mysterious" 15-member "assassination squad" who were allegedly involved in Khashoggi's disappearance.
TV channels broadcast videos of what they said were the men arriving at the airport and checking into hotels, as well as footage of auto traffic outside the consulate before and after Khashoggi's disappearance, including a black van with blacked out windows that the police find suspicious.
Mr Trump said that he wanted to invite Khashoggi's fiancée, Hatice Cengiz, to the White House, in a step that is likely to be taken as a personal rebuke to Crown Prince Mohammed bin Salman, Saudi Arabia's effective ruler, who was previously regarded as an ally of the Trump administration.
"We're working very closely with Turkey and I think we'll get to the bottom of it", Trump said today. There are also reports that Turkish intelligence is in possession of a video showing Khashoggi's murder.
US Secretary of State Mike Pompeo has called for Saudi Arabia to support an investigation into Khashoggi's disappearance.
Sabah newspaper published the names and years of birth of the 15 Saudis it said arrived at Istanbul's Ataturk airport.
University of Texas law professor Steve Vladeck weighed in on this revelation, saying it's "remarkable" that the US had this intelligence and seemingly failed to act on it. The footage does not show Khashoggi himself leaving the consulate.
She wrote: 'Although his opinions had angered certain people, he said, the tensions between himself and Saudi Arabia did not amount to hate, grudges or threats. Suggestions that Khashoggi was killed and his body then mutilated have gained wide circulation in the week since he vanished, and Turkish officials continue to insist he met a brutal fate when he stepped through the doors of the diplomatic mission. The New York Times and the Washington Post both reported that private planes carrying Saudi Arabian agents arrived in Istanbul shortly before and after Kashoggi entered the consulate and left the same day.
