Cavusoglu is currently in the United States at an anti-ISIL coalition gathering as well as meeting the U.S. authorities on several issues.

Speaking late on Wednesday in New Jersey at a gathering about Turkey’s upcoming constitutional referendum, Cavusoglu said Ankara had raised the extradition of Fetullah Gulen once again with the U.S. authorities.

He said Turkey had again provided additional evidence not only for Gulen’s extradition but also to secure a provisional arrest warrant for the fugitive until the extradition process began. 

"Turkey expects the Trump administration to take steps in this regard," the minister said.

Gulen, leader of Fetullah Terrorist Organization (FETO) -- accused of orchestrating the failed 15 July 2016 coup attempt in Turkey which left 249 people martyred, and around 2,200 others wounded -- resides in the U.S. state of Pennsylvania.
