HOUSE OVERSIGHT 031481 Since the failed coup that led to the deaths of 271 people, Turkish President Recep Tayyip Erdogan has accused the imam, Fethullah Gulen, of issuing instructions to launch the coup, a charge Mr. Gulen has denied. Turkish authorities have demanded the U.S. extradite Mr. Gulen immediately to Turkey, but The Wall Street Journal reported Thursday that U.S. officials don't expect to do that, citing people familiar with the discussions. U.S. officials see problems with the evidence presented thus far by Turkey, and they are concerned about strident public statements made by Turkish leaders against Mr. Gulen, those people said. Mr. Erdogan has called Mr. Gulen and his supporters a terrorist network, a charge U.S. officials have long discounted. Turkey in May officially designated Mr. Gulen's network a terrorist organization, making membership a crime under Turkish law. Mr. Erdogan's government has pressed the Obama administration since the coup to extradite Mr. Gulen, arguing that pursuing the imam is part of the broader campaign against terrorism. At times, the Turkish leader's aides have said Ankara would view as hostile any foreign government that gave sanctuary to leaders of the Gulen movement. Turkey hasn't yet made a formal extradition request to the U.S., and Turkish officials say they plan to provide more evidence to the Justice Department. Mr. Gulen, 75 years old, came to the U.S. in 1999, and has a devoted following in Turkey and other countries. At a press conference in Washington on Friday, Mr. Gulen's lawyers said they have spoken to the Justice Department about the demands for extradition but are unaware of the U.S. government's thinking or plans. Asked if they feared for his life, one of Mr. Gulen's lawyers, Reid Weingarten said, "We do. We're very concerned about his safety." The lawyer said they are discussing whether to ask U.S. authorities for help in safeguarding their client. A Turkish court has issued a war
