Gulen, a reclusive Islamic preacher with a worldwide following who is regularly accused of a behind the scenes role in Turkish politics, lives in a tiny town in the Pocono Mountains of the US state of Pennsylvania.
He has been accused by Turkish President Recep Tayyip Erdogan of being behind the Thursday`s boody coup attempt, although he has denied any role and condemned the miliary uprising "in the strongest terms."
The Turkish PM said that any country that stood with Gulen was at a state of "war" with Turkey.
Kerry who spoke late Friday to his Turkish opposite number Mevlut Cavusoglu by telephone, said: "We haven`t received any request with respect to Mr Gulen.
"And obviously we invited the government of Turkey as we always do to present us with any legitimate evidence that withstands scrutiny and the United States will accept that and look at it and make judgments about it appropriately."
