"We now see that it wasn't just cut up, [the Saudi suspects] got rid of the body by dissolving it", Yasin Aktay, an adviser to Recep Tayyip Erdoğan and an official in Turkey's ruling party, told the newspaper Hurriyet on Friday.
The cutting of aid by Gates Foundation came amidst reports that Crown Prince Salman had disparaged Khashoggi as a member of the Muslim Brotherhood, in talks with U.S. officials, after the journalist's murder.
What has the investigation found so far?
Fidan, the Istanbul prosecutor, on Wednesday said that Khashoggi was strangled shortly after entering the consulate and that his body was dismembered afterward.
Much of the information pertaining to the case has already been leaked to Turkish media, but the strengthening of Turkey's official position suggests that Ankara is unwilling to let up on rivals in Riyadh in the search for answers in Khashoggi's death. He entered the consulate to sort out documents for his marriage to his Turkish fiancée, Hatice Cengiz.
Saudi Arabia has long insisted that normalizing relations with Israel requires its withdrawal from Arab lands captured in the 1967 Middle East war - which Palestinians seek for a future state.
When he first disappeared, it said Khashoggi had walked out of the building alive. However, as global pressure increased, Riyadh admitted that the killing was an error, carried out by rogue elements. Turkey wants the suspects to be extradited.
But Pompeo emphasized, as Trump has, that "not only do we have important commercial relationships, but important strategic relationships, national security relationships with the Kingdom of Saudi Arabia, and we intend to make sure that those relationships remain intact".
US Secretary of State Mike Pompeo has said it may take "a handful more weeks" before Washington has enough evidence to impose sanctions on individuals responsible for the killing of Saudi journalist Jamal Khashoggi.More news: Bomb suspect set for Florida court appearance
Mr Pompeo said the USA had "deep and long-term strategic relationships" with Saudi Arabia and said "we intend to make sure that those relationships remain intact".
On Wednesday, France's Foreign Minister Jean-Yves Le Drian said Khashoggi's death was a "crime" and "odious".
UK Foreign Secretary Jeremy Hunt also said it was an appalling act, adding that it had "possibly" given the USA and the UK a chance to put new pressure on Saudi Arabia over other issues.
Recent reports also speculate the journalist may have been assassinated for preparing a report about the planned use of chemical weapons by the Saudi-led coalition fighting in Yemen.
In an editorial published in five worldwide newspapers, Ms Cengiz said Khashoogi had just bought a house and wished to start a family.
"We must all send a clear message that authoritarian regimes can not kill journalists ever again".
Speaking at a journalism awards ceremony Thursday, Fred Ryan, Publisher and CEO of the Washington Post which Khashoggi wrote for, urged the Trump administration to take a tougher line.
"It is now up to the worldwide community to bring the perpetrators to justice".
