On Tuesday, Trump vowed to remain a "steadfast partner" of Saudi Arabia despite saying that Saudi Crown Prince Mohammad bin Salman may have known about the plan to murder Khashoggi last month.
Speaking to broadcaster CNN Turk, Cavusoglu also said the United States had not informed Turkey of an audio recording regarding Khashoggi's killing, after a Turkish daily reported that the CIA was in possession of a recording in which the Crown Prince ordered to "silence Khashoggi".
He also said there was no reason President Recep Tayyip Erdogan and the crown prince could not meet during a visit to Argentina for the G-20 summit, adding the final decision was Erdogan's.
