“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.
Erdogan said last week Turkey would start new initiatives abroad to target the financing of Gulen supporters.
“I have recently seen a credible probe by the FBI on how the Gulen organization avoids taxes,” Cavusoglu told a conference in Doha.
