The West Point graduate, who according to The New York Times twice declined the diplomatic post, will now be competing with a longstanding backchannel between Trump's son-in-law Jared Kushner and Saudi Crown Prince Mohammed bin Salman.
The call is believed to be between Maher Abdulaziz Mutreb-one of the Saudi agents at the consulate-and an aide to the crown prince.
Speaking to journalists on board his plane while returning from World War I commemorations in Paris, Recep Tayyip Erdogan also reportedly said audio recordings of the killing that Turkey shared with officials from Saudi Arabia and other nations were so "atrocious" that a Saudi intelligence official speculated that the killer may have been on heroin.
Items found inside the squad's bags included; 10 telephones, five radios and wireless intercoms for those radios, two separate syringes, two defibrillators, one technical monitoring jammer, three staplers and a cutting tool similar to a scalpel.
A senior Turkish official proposed on Wednesday that suspects in the killing of Saudi journalist Jamal Khashoggi be tried in a Turkish court observed by worldwide human rights groups.
"He said this to my special envoys", Erdogan was quoted as saying.
On Tuesday, he described the recording as "appalling", and said that a Saudi intelligence officer was shocked when he listened to the audio.
The Trump administration, by all appearances, is unsure of how to proceed in its response to Khashoggi's murder; while officials have been promising to clamp down hard with possible sanctions against senior Saudi leaders, little action has been taken, likely due to the deep economic ties between Washington and Riyadh.
Babar's 92 lift Pakistan to 279-8 against New Zealand
Pakistan had high hopes as it was their chance to register their first ODI series win against the New Zealanders. Taylor hit three boundaries and a six for his 43rd half century in one-day internationals.
He has gone back and forth between demanding full accountability for the journalist's murder and emphasising the strategic importance of the US-Saudi alliance, going so far as to say any punishment imposed on Riyadh will not include a halt to US arm sales.
The crown prince is not specifically mentioned by name during the audio recording, according to the Times.
Khashoggi was killed shortly after entering the Saudi consulate in Istanbul on October 2.
Turkey has said a 15-member Saudi "hit squad" strangled and dismembered Khashoggi at the consulate.
Saudi Arabia's prosecutor Saud al-Mojeb has since said Khashoggi's killing was planned in advance, although another Saudi official said Prince Mohammed had no knowledge of the specific operation.
The Crown Prince said: "We have assigned departments concerned with the families of the martyrs to fulfill their requirements". Ankara insists the orders for the killing came from the highest levels of the Saudi government, but not King Salman.
President Donald Trump on Tuesday (Nov 13) tapped General John Abizaid, a top USA general from the Iraq war who has studied the Middle East for years, as ambassador to Saudi Arabia amid growing friction between the longstanding allies.
