"We have seen no credible evidence that Mr. Brunson is guilty of a crime and are convinced that he is innocent," Nauert said on Monday.

We hope that the judicial system in Turkey will resolve his case in a timely, fair, and transparent manner."
The American pastor and his wife were detained in October on the Turkish coastal town of Izmir, where he has carried out his ministry for roughly 20 years, US media reported.
Earlier, Turkish President Recep Tayyip Erdogan asked Washington to extradite cleric Fethullah Gulen, who Ankara believes was the plotter of the 2016 failed coup attempt, and saying "we will do what we can within our judiciary," hinting at the release of pastor Andrew Brunson.
