The ’Splainer (as in, “You’ve got some ’splaining to do”) is an occasional feature in which RNS gives you everything you need to know about current events to help you hold your own at a cocktail party. (RNS) Turkey’s crackdown of those suspected in the failed July 15 military coup widens, with the firing of 492 people at its top Islamic authority. And Turkish President Recep Tayyip Erdogan is zeroing in on a Muslim cleric living in rural Pennsylvania, whom he accuses of masterminding the coup. Reclusive Turkish imam Fethullah Gulen, who lives in a gated compound in the Poconos, denies involvement and disavows violence. Erdogan is pressuring the U.S. to extradite Gulen, but Secretary of State John Kerry, rejecting insinuations that the U.S. was involved in the coup, said it awaits a formal extradition request and proof of Gulen’s involvement.
