US Secretary of State John Kerry says the United States would entertain an extradition request for exiled cleric Fethullah Gulen, whom Turkey's president blames for a failed coup.
But Kerry adds Turkey's government would have to present evidence of Gulen's wrongdoing that withstands scrutiny.
While visiting Luxembourg, Kerry says Turkey hasn't made a request to send the Pennsylvania-based Gulen home.
But he says he anticipates questions about Gulen, who has condemned the coup.
Kerry says on Saturday the US opposed any attempt to overthrow a democratically elected leader.
He says change must come through a constitutional process.
Kerry also says US military cooperation with its NATO ally has been unaffected by the turmoil.
Turkey plays a key role in US-led efforts against the Islamic State group in Syria and Iraq.
