Bob Baer, who worked as a Central Intelligence Agency case officer primarily in the Middle East, told CNN's Jake Tapper that the United States has purposely muted its response to Khashoggi's murder, despite mounting evidence - including audio recordings - that some suggest implicates the Saudi Crown Prince.
Jamal Khashoggi, a Saudi journalist and Washington Times contributor, was last seen entering the Saudi consulate in Istanbul on October 2.
A member of the Saudi kill team responsible for the assassination at the Saudi Consulate in Istanbul reportedly can be heard saying on the phone, "tell your boss" and "the deed was done", after Khashoggi was murdered.
Erdogan told reporters on his plane returning from a weekend visit to France that he discussed the Saudi journalist's killing with the US, French and German leaders at dinner in Paris.
'We played the recordings regarding this murder to everyone who wanted them from us. Our intelligence organisation did not hide anything.
"The recordings are really appalling". Turkey's president said that the recording "shocked" a Saudi intelligence officer and that MBS promised to "shed light on this incident" and do "whatever is necessary". Citing three unnamed people familiar with the recording, the report claimed that U.S. intelligence officials believed the "boss" was the Saudi crown prince.
While Turkish and US officials, including US National Security Adviser John Bolton, have said that the audio does not conclusively implicate Prince Mohammed, Baer suggested it is unlikely that anyone else in the Kingdom would have the authority to order such an operation.
Samples taken from the drains at the Saudi consulate in Istanbul showed traces of acid, pro-government daily Sabah said, without quoting sources.
Still, Khashoggi's body has not been returned, and audio recordings circulating around government agencies appear to indicate that that someone senior, possibly Crown Prince Mohammed bin Salman, had ordered the killing. "We are waiting patiently", Erdogan said, adding that the perpetrators of the killing were among 18 suspects detained in Saudi Arabia.
'It must be revealed who gave them the order to murder'.
It comes as Turkey's president claimed the audio recordings of Jamal Khashoggi's murder were so "appalling" that a shocked Saudi intelligence officer who listened to them said the killer must have been on heroin.

Prince Mohammed has tightened his grip in the previous year since being appointed Crown Prince last June at the age of 31.
Trump now says Saudi Arabia misused USA -supplied weapons in the Saudi-led coalition's bombing campaign in Yemen, which has helped trigger the world's worst humanitarian crisis.
He also supervised the brief detention, humiliation and beating of Lebanese Prime Minister Saad al-Hariri a year ago. The images are said to have been taken as the Saudis passed through security checks at the terminal when they left the country. Reuters could not immediately verify the Sabah report.
Under mounting pressure, Saudi Arabia has changed its narrative about Khashoggi's killing.
Saudi Arabia initially denied any knowledge or involvement in Khashoggi's killing, but a Saudi public prosecutor later said it was planned in advance.
