According to that narrative, the crown prince had approved an interrogation or rendition of Khashoggi back to Saudi Arabia, but the intelligence official was tragically incompetent as he eagerly sought to prove himself.
Saudi Arabia agreed last week to allow Turkish officials to conduct a search but insisted it would only be a superficial "visual" inspection.
October 10: Trump makes his first comments on Khashoggi's disappearance, saying he contacted the Saudis and invited Cengiz to the White House.
Trump says he doesn't "want to get" into King Salman's mind, but says, "it sounded to me like maybe these could have been rogue killers".

The US president announced that he had dispatched Secretary of State Mike Pompeo to the kingdom and anywhere else necessary to get to the bottom of the apparent demise of Khashoggi, a Saudi who had been living and working in the United States.
A Saudi team investigating the disappearance of journalist Jamal Khashoggi has left the Saudi consulate building in Istanbul, a Reuters witness said on Tuesday. He was joined on the plane by David Hale, the under secretary for political affairs, and Tim Lenderking, a deputy assistant secretary for Arabian Gulf affairs, among others.
Jamie Dimon, JPMorgan Chase's chief executive and chairman, has decided not to participate in Saudi Arabia's "Davos in the Desert" event this month as the outrage over the disappearance of journalist Jamal Khashoggi continues to grow. "There's something really bad and disgusting about that if that were the case", he said, referring to allegations by Turkish authorities that Saudi Arabia was involved.
But Trump, who has frequently boasted about his business ties with the kingdom, suggested during the CBS interview that ending USA arms sales to Saudi Arabia would not be an option, saying, "I don't want to hurt jobs".
"His denial to me could not have been stronger", Trump said, echoing language he has used to describe Russian President Vladimir Putin's denials of meddling in the 2016 election that sent Trump to the White House.
U.S. Senator Marco Rubio and Senator Jeff Flake, members of the Foreign Relations Committee, said Congress was prepared to move quickly and firmly if Trump failed to adequately respond to the October 2 disappearance of Khashoggi. While lurid claims have appeared in Turkish media - including that Khashoggi was tortured and dismembered - Turkey's leadership has so far refrained from pointing the finger directly at Riyadh in public comments.
King Salman and Turkish President Tayyip Erdogan spoke by telephone on Sunday evening and stressed the importance of the two countries creating a joint group as part of the probe.
On Sunday, Saudi Arabia warned that if it "receives any action, it will respond with greater action". He said the U.S. was working with Saudi Arabia and Turkey to figure out what happened.
Rubio's comments come a day after Trump vowed "severe punishment" for the U.S. ally if they were found responsible.
White House economic adviser Larry Kudlow declined to speculate on what Trump might do after the president promised "severe punishment" in a "60 Minutes" interview, if the US determines that Khashoggi was indeed killed inside the Saudi consulate in Istanbul.
