Back in Istanbul, the government of Turkish President Recep Tayyip Erdogan appeared more serious about trying to discover the truth. The three posed for photos, but said nothing in front of reporters.
Mr Khashoggi, a USA resident and critic of the Saudi regime, has been missing since 2 October when he visited the Saudi embassy in Istanbul to obtain documents.
US Secretary of State Mike Pompeo on Wednesday held talks with the Turkish leadership in Ankara over the disappearance of Saudi journalist Jamal Khashoggi as Riyadh faced new claims he was killed inside its Istanbul consulate.
"Pompeo's mission in travelling to Riyadh and then Turkey is to cover up Saudi brutality and scandal by making up stories, and this very project is an excuse to keep milking the Saudis (for weapons' contracts)", added the Javan newspaper, considered close to the Revolutionary Guards.
However, no major decision is made outside of the ultraconservative kingdom's ruling Al Saud family.

But CNN cited two sources as saying the Saudis are preparing a report that his death resulted from a botched interrogation, while the Wall Street Journal said the kingdom was weighing whether to say that rogue operatives killed Khashoggi by mistake. The secretary of state noted that the Saudi leaders, while denying knowledge of anything that occurred inside the consulate, had committed to accountability "including for Saudi Arabia's senior leaders or senior officials".
'We encourage joint Saudi-Turkish efforts in that regard, and expect the Saudi Government to provide a complete and detailed response'.
The Saudi government has repeatedly denied any involvement in the journalist's disappearance and in a statement Sunday warned that "if it receives any action, it will respond with greater action".
"Here we go again with you're guilty until proven innocent", Trump told The Associated Press as he compared the allegations against Saudi Arabia to the sexual misconduct allegations from multiple women against Supreme Court Justice Brett Kavanaugh during his confirmation hearing.
Turkish officials say they have evidence Riyadh critic Jamal Khashoggi was killed in Istanbul.
Senator Lindsey Graham, a strong Trump ally in Congress, called bin Salman a "wrecking ball" and "toxic" figure. The official spoke on condition of anonymity because the investigation was ongoing.
CCTV footage showed diplomatic cars travelled to the consul general's home shortly after Mr Mr Khashoggi disappeared.
Turkish police teams arrived at the Saudi consul general's residence in Istanbul on Tuesday and started searching it in relation to the case. The search, however, did not happen overnight and reasons for that weren't immediately clear. Several Republicans have said arms sales should be curtailed, and Senator Bob Corker of Tennessee, the Republican chairman of the Foreign Relations Committee, said last week that he had warned the Saudis that their relationship with the USA risked collapsing. Publicly, Saudi Arabia so far has issued only denials in response to reports of Turkish claims that Khashoggi was murdered.

Trump sent Pompeo to meet with the Saudi king in Riyadh on Monday and said Pompeo may travel to Turkey as well.
