Turkey wants an global probe into the murder of Saudi journalist Jamal Khashoggi, Ankara said on Wednesday.
Mr Trump has championed a hard line on Iran, Saudi Arabia's regional rival.
"At the current stage we believe an global investigation is a must", Foreign Minister Mevlut Cavusoglu was quoted as saying by the state-run Anadolu news agency.
"We will do whatever needed to shed light on all its aspects of this murder", Cavusoglu said.
Turkey previously said it would cooperate in an global investigation, and had called for a United Nations probe.
French Foreign Minister Jean-Yves Le Drian on Monday said that France was not in possession of recordings related to the killing of Saudi journalist Jamal Khashoggi, as far as he was aware.
Turkish officials have shared an audio recording of the killing with American and other Western intelligence agencies.
Earlier this week, The New York Times reported that shortly after Khashoggi was killed, a member of the alleged assassination squad - a man believed to be Maher Abdulaziz Mutreb - told a superior over the phone to "tell your boss".
The 59-year-old journalist, who was considered close to the Saudi royal family, had became a critic of the current government and Crown Prince Mohammed bin Salman, the 33-year-old heir apparent who has introduced reforms but shown little tolerance for criticism. Saudi officials have said the crown prince had no involvement in or knowledge of the operation.
Saudi Arabia's top prosecutor is recommending the death penalty for five suspects charged with ordering and carrying out the killing of Saudi writer Jamal Khashoggi, in a move that appears created to protect the country's powerful crown prince Mohammed bin Salman. Trump has so far chose to stand by Crown Prince Mohammed despite the scandal, people familiar with the White House strategy have said. This contradicts remarks by Turkey's President Recep Tayyip Erdogan.
With the Saudi prosecutor expected this week to announce findings that the kingdom's rulers hope will close the case, the Turkish foreign minister's remarks Wednesday appeared meant to remind the Saudis that Ankara will continue pushing the question of responsibility.
Khashoggi, a frequent contributor to The Washington Post, was killed on October 2 inside the Saudi Consulate in Istanbul.
Any global investigation would complicate the efforts of Saudi Arabia and its allies to move past the episode.
