“In Argentina, Trump told Erdogan they were working on extraditing (Fethullah) Gulen and other people,” Mevlut Cavusoglu said, referring to the G20 summit where the leaders met two weeks ago.

Turkey has long sought the extradition of Gulen, who has lived in self-imposed U.S. exile for nearly two decades. A former ally of Erdogan, he is blamed by Turkish authorities for the failed coup when rogue soldiers commandeered tanks and helicopters, attacked parliament and shot unarmed civilians.
