The Washington Post reported on Tuesday that USA intelligence had intercepted the communications of Saudi officials discussing a plan to capture Khashoggi, citing an unidentified person familiar with the information.
Riyadh has said Khashoggi left the consulate after his visit. "We can not let this happen, to reporters, to anyone".
She wrote that she was "confident in the abilities of Turkish government officials".
Speaking during a radio interview earlier on Wednesday, Vice President Mike Pence said the United States "stands ready to assist in any way" in the investigation.
He said the U.S.is working closely with Turkey on the investigation and wants to "get to the bottom of it".
He was also a United States resident living in self-imposed exile in Washington.
Once Mr. Trump has determined "whether a foreign person is responsible for an extrajudicial killing, torture, or other gross violation of internationally recognized human rights against an individual exercising freedom of expression", according to the letter, he must report to the committee within 120 days with a decision on the imposition of retaliatory sanctions.
"I'm not happy about it", Trump said of Khashoggi's disappearance. "Violence against journalists should be condemned, but at this point, we don't know what happened". Saudi Arabia, however, has been a major U.S. ally in the Middle East since WWII, including serving as the launching pad for the 1991 Gulf War and, most recently, as the linchpin of regime change efforts directed against Iran and Syria.
"Any country that makes such claims. just wants to display its support for the USA sanctions against Iran", Zanganeh was quoted as saying.
Khashoggi had written a series of columns for the Washington Post that were critical of Saudi Arabia's assertive Crown Prince Mohammed bin Salman, who has led a widely publicized drive to reform the Sunni monarchy but has also presided over the arrests of activists and businessmen.More news: Google Shutters Google+ Following Privacy Vulnerability
Turkish television Wednesday released CCTV footage showing the moment missing Saudi journalist Jamal Khashoggi entered the kingdom's consulate in Istanbul and the movements of a team suspected of involvement in his disappearance.
A screenshot of Khashoggi entering the consulate taken by a Turkish police camera, at 1:14 pm on October 2 is the last known image seen of the writer who was living in exile between Washington DC and Istanbul.
She called on Trump to "help shed light" on the journalist's disappearance. Twelve of them arrived early on Tuesday, based on photos captured at passport control which it published.
News channel 24 aired the video, suggesting that Khashoggi was inside of the black Mercedes Vito, which resembled one parked outside of the consulate when the writer walked in on October 2.
Officials also say they had become aware that Khashoggi may have been kidnapped before the second plane had departed, and monitored seven Saudis in a waiting room as they checked their luggage for a second time.
Sen. Bob Corker (R-Tennessee) reportedly spoke to a Saudi ambassador about viewing security video that would show whether or not Khashoggi left the consulate.
Turkey says it will conduct a search of the Istanbul consulate, while Saudi Arabia's foreign ministry said the country was "open to co-operation" and a search of the building could go ahead.
Saudi Arabia denies those allegations, saying Khashoggi exited the building shortly after his business there was conducted.
"We have to get an outcome from this investigation as soon as possible". "It has to prove that Jamal wasn't oppressed at the consulate and that he left safely".
"I would normally prefer not to address such outrageous claims, especially when it concerns the well-being of a missing citizen who dedicated a great portion of his life to serve his country", Khalid bin Salman said in a statement.
