Freeland said she's been in contact with her G7 and North Atlantic Treaty Organisation counterparts, including U.S. Secretary of State Mike Pompeo, as well as the German, British and Turkish foreign ministers.
Security services in Turkey have used pro-government media to leak details of Khashoggi's case, adding to the pressure on the kingdom.
Trump has threatened "severe punishment" if it turns out Khashoggi was killed in the consulate, although he has ruled out cancelling arms deals worth tens of billions of dollars with Saudi Arabia. After saying yesterday that King Salman has issued a "flat denial", Trump updated that statement to say that Salman's son, the crown prince, had "totally denied any knowledge of what took place in their Turkish Consulate". Khashoggi was a USA resident who wrote columns for the Washington Post and he was critical of the Saudi government, calling for reforms.
It also said that a person with knowledge of the discussions said the kingdom will claim that rogue operatives killed the journalist during either an interrogation or an attempt to kidnap him and return him to his native Saudi Arabia.
Pompeo thanked Saudi King Salman for his commitment to a thorough, transparent investigation of Saudi writer Jamal Khashoggi's disappearance, while the crown prince assured him that the U.S. and Saudi Arabia are "old, strong allies".
The semiofficial Anadolu news agency said Saudi's Istanbul Consul General, Mohammed Otaibi, had left the country.
Over the past two days, Saudi Arabia has allowed Turkish police to search the consulate.
The report came as US Secretary of State Mike Pompeo held talks with Turkish officials in Ankara about Khashoggi's disappearance - a day after visiting Riyadh to discuss the mystery with Saudi King Salman and Crown Prince Mohammed bin Salman.
In August, Saudi Arabia reacted strongly to a tweet from Freeland calling for the immediate release of detained activists, including Samar Badawi, a champion of women's rights and the sister of detained blogger Raif Badawi.
While Pompeo said the Saudis would conduct a "thorough" investigation and hold any guilty parties completely accountable, he flat out shut down any conversation of the facts of the case.
After his talks in Riyadh on Tuesday, Pompeo was expected in Turkey today to meet Turkish Foreign Minister Mevlut Cavusoglu.
She said under global law, both a forced disappearance and an extra-judicial killing were "very serious crimes" and immunity should not be used to impede investigations into what happened and who is responsible.
Which begs the wider question: is the West's relationship with Saudi Arabia so important that it outweighs the need to condemn and punish what many believe was a state-sponsored murder of a journalist inside a consulate?
"It sounded to me like maybe these could have been rogue killers", Trump said. The Saudis initially denied that this happened, but without any video evidence that he ever left the consulate, they've seemingly painted themselves into a corner.
"This is going to alter the relationship between the United States and Saudi Arabia for the foreseeable future", Sen.
"The specific transfer of funds has been long in process and has nothing to do with other events of the secretary's visit", McGurk was quoted by the Times as saying.
