Turkish President Tayyip Erdogan has said the order for Khashoggi's killing came from the highest level of the Saudi government but probably not King Salman, putting the spotlight instead on Salman's heir and de facto ruler Prince Mohammed.
CIA Director Gina Haspel briefed two Senate committees on Capitol Hill earlier on Tuesday on the agency's findings about Khashoggi's murder.
Graham said that President Trump has worked to create a strong relationship with Saudi Arabia, and he "clearly" isn't being respected. It says Saudi Arabia should be held accountable for "contributing to the humanitarian crisis in Yemen, the blockade of Qatar, the jailing of political dissidents within Saudi Arabia, the use of force to intimidate rivals, and the abhorrent and unjustified killing of journalist Jamal Khashoggi". He said it seemed as though the White House's response to the Khashoggi killing was that "you can kill a journalist".
"It is a zero chance, zero, that this happened in such an organized fashion without the crown prince", Graham told The Washington Post. "By extraditing all suspects to Turkey, where Jamal Khashoggi was killed and dismembered, the Saudi authorities could address those concerns", the Turkish official said.
Graham made the unambiguous rebuke following a classified briefing on the murder with CIA Director Gina Haspel, who is one of the only US officials who listened to the audio recording of Khashoggi's death.
"It is wrong to suggest that maintaining USA alliances consists of mutually exclusive choices between power and principles", he said.
"There's not a smoking gun".

Settimino Mineo, center, who allegedly took over as the Palermo head of Cosa Nostra, is escorted by Italian Carabinieri police. He also confirmed that there had been raids in Suriname, a small South American country that was once a Dutch colony.
Sen. Marco Rubio, R-Fla., concluded the crown prince was involved and suggested in a CNN interview Wednesday that Mattis and Pompeo were both technically accurate and echoing the administration's position.
Saudi Arabia has detained 21 people and seeking the death penalty for five. In recent months, Mattis - a former Marine four-star popular with lawmakers - has defended other politically controversial moves by the Trump administration, like troop deployments to the USA border and plans to reorganize the military for a Space Force.
Senators who weren't invited to Tuesday's briefing, including Rand Paul of Kentucky, Chris Murphy of CT and Tim Kaine of Virginia, where Khashoggi lived, said more senators should also get the same briefing.
Graham, who is a member of the armed services and foreign relations committees, told Fox News that he he could no longer support arms sales to Riyadh under Mohammed, who he called "a wrecking ball when it comes to the Mideast".
Pompeo and Mattis are now expected to give a briefing to the House on Yemen and Saudi Arabia on December 13, ahead of a Democratic takeover of the House in January following the party's gains in the midterm elections.
A senior Turkish official said on Wednesday that the prosecutor's move "reflects the view that the Saudi authorities won't take formal action against those individuals". If it advances beyond that, senators have an opportunity to debate and add amendments to the resolution before a final vote.
