Turkish officials have said that a 15-person team flew from Saudi Arabia into Istanbul on the day Khashoggi entered the consulate, and they have provided information about two private planes that, they say, were involved in the transit of these Saudis.
Khashoggi's fiancee, Hatice Cengiz, said she waited for him and he never came back out on October 2. The Turkish leader rejected commenting on allegations that Khashoggi was killed at the consulate, but said he was anxious, Efe news reported.
Shortly after Graham's remarks, Trump said in the Oval Office that he has already spoken with high-level Saudi officials about Khashoggi.
"We are anxious about this case", al-Otaibi said. "We want to see what's going on". He also said the USA was working "very closely" with Turkey, "and I think we'll get to the bottom of it".
Trump said that the United States is working closely with Turkey to find out what happened to Khashoggi.
"People saw him go in and didn't see him come out". "It's being investigated, it's being looked at very, very strongly. It's a awful thing", Trump said. "We can not let this happen, to reporters, to anyone".
'And we can not let this happen.
The president had been criticised for his mild response to the disappearance of the journalist, with members of Congress imploring his administration try to get to the bottom of the disappearance.
The team members departed immediately after Khashoggi's disappearance.
"I think that would be hurting us", Mr Trump said.
"Frankly I think that would be a very very tough pill to swallow for our country".
"If it did happen there would be hell to pay", Graham said.
But after several of his friends were arrested, his column was cancelled by the al-Hayat newspaper and he was allegedly warned to stop tweeting, Mr Khashoggi left Saudi Arabia for the US.

In addition, Bloomberg , the New York Times , the Financial Times , CNN and CNBC have all cut their ties with the conference. The oil-rich kingdom has called the allegations "baseless", but has offered no evidence the writer ever left the consulate.

There is a chance of gusts of 70 to 80 miles per hour in the Western Isles during Friday afternoon and evening. There are also risks of coastal flooding, and the warning is in place from 10pm Thursday until 12pm Friday.
Trump told reporters at the White House that he talked to the Saudi leadership "more than once" since Khashoggi, a United States resident and Washington Post contributor, vanished on October 2 after entering the Saudi consulate in Istanbul.
U.S. Secretary of State Mike Pompeo followed up with his own call to the crown prince, who had forged close ties to the administration, especially Kushner.
"We can not have an ally who murders in cold blood in their own consulate", said Mr. Sanders.
"But I will be at some point", he said Tuesday, without elaborating.
"At this time I implore President Trump and First Lady Melania Trump to shed light on Jamal's disappearance", wrote Cengzi.
Earlier this month, Trump suggested Saudi Arabia's king "might not be there for two weeks" without USA military support.
Trump said that he's been in touch with the "highest levels" of the Saudi government about Khashoggi's case and expressed concerns about his possible murder.
Khashoggi, a prominent critic of Riyadh and a USA resident, disappeared on October 2 after visiting the Saudi consulate.
The investigators have found that all 15 men had booked four nights in two hotels situated near the Saudi consulate but left Turkey less than 24 hours after arriving. The Post report cited USA intelligence intercepts of Saudi officials discussing the plan, as well as interviews with some of Khashoggi's friends.
National security adviser John Bolton and senior adviser Jared Kushner, President Donald Trump's son-in-law, talked with Salman on Tuesday, while Secretary of State Mike Pompeo had a follow-up call with the Saudi leader to reiterate the USA demand for information about the case, the White House said.
He called that statement "not credible" and he said it's now up to the Saudi government to clarify the situation. He said if they have footage of Khashoggi leaving the consulate, they should release it, the Associated Press reports.
With every day, leaks from the Turkish investigation are drip-fed to the media here - and hope that Jamal Khashoggi might still be alive fades further.
Twelve of them arrived early on Tuesday, based on photos captured at passport control which were published.
