>> A deeper chill between Turkey and the United States. Prosecutors in Istanbul reportedly sending a formal letter to Washington, demanding the detention of this man, Fethullah Gulen, alleged by Turkish authorities to be the mastermind of July's failed coup attempt. The latest in a string of such requests for Gulen, the Islamic cleric living in self-imposed exile at this estate in rural Pennsylvania.
Gulen is the head of a Turkish popular movement. And his followers have established a massive network of business and secular schools outside of Turkey, including in the United States.>>
> But Turkish President Erdogan has accused his former ally of running a shadowy cabal inside his government.
Since the coup attempt, Erdogan has purged thousands of government workers, including judges, members of the military, and teachers. He accuses them all of being Gulen followers. He's also encouraging a very public warming of relations between Russia and Turkey, a NATO member. Gulen has condemned and denied the coup.
Washington says it will not extradite the man without proof of his involvement.
