While several Republican and Democratic members of Congress have said the crown prince either knew or even ordered the operation, President Trump has so far repeated the Saudi line that both men denied any knowledge.
Turkey and Western allies of Riyadh have voiced deep scepticism about Saudi explanations of the killing.
In a newspaper column Ilnur Cevik described the Khashoggi case as a "disgrace that reaches all the way to Crown Prince (Mohammed bin) Salman".
Turkish investigators continue to hunt for clues to the whereabouts of Khashoggi's body.
The Saudis on Friday admitted he died within their consulate, after first saying he walked out, and alleged he was killed in a fist fight that broke out during his visit.
The European Parliament passed a nonbinding resolution Thursday urging an EU-wide arms embargo on Saudi Arabia in response. But Saudi authorities refused to allow Turkish police to search a well in the garden of the consulate in Istanbul, according to Turkey's state-run Andalou agency.
"The Public Prosecution continues its investigations with the accused in the light of what it has received and the results of its investigations to reach facts and complete the course of justice", the official news report reads. Erdogan called it a "brutal" murder.
Saudi state media said they offered their condolences to the family, but pictures of the prince shaking hands with Salah went viral on social media, where rights activists demanded the immediate lifting of the travel ban.

Trump says Saudi prince vows 'full' probe into missing journalist
His remarks came after Saudi authorities claimed early Saturday that Khashoggi died in a fight inside its Istanbul consulate. He also urged Turkey to turn over purported audio recordings of Khashoggi's killing inside the Saudi consulate in Istanbul.
Megyn Kelly’s Show In Jeopardy After She Defends The Use Of Blackface
Ailes in her memoir, who left the network after multiple women made allegations of sexual misconduct against him. As more of her newsmagazine shows aired, those comments made Kelly look downright delusional.
Two informed sources told Reuters today that Central Intelligence Agency director Gina Haspel heard an audio recording of the killing during a fact-finding visit to Turkey this week, the first indication Ankara has shared its key investigative evidence.
Saudi Arabia initially maintained that Khashoggi, who had been writing critical columns in The Washington Post, had left the consulate alive on October 2.
The latest change came Thursday when the Saudi prosecutor announced that the murder of Khashoggi was premeditated, three days after a Saudi official told ABC News, "There was never a plan to kidnap or kill him".
In his toughest comments yet, Trump told the Wall Street Journal he wanted to believe the prince when he said that lower level officials were to blame for the killing at the Saudi mission.
Turkey has long dismissed the Saudi assertion of an accidental death and has pressed the kingdom to concede that Khashoggi was deliberately targeted for death.
Trump also said the USA has sent officials to Saudi Arabia to get more information on the killing, which has spiraled into a crisis. Last week, its government changed its story, saying the USA resident and critic of Saudi policy had died in the consulate because of a fight.
The United States has threatened sanctions if the Saudi leadership is linked to the murder, and on Tuesday revoked the visas of 21 Saudi nationals implicated in the crime.
