Fethullah Gülen, a reclusive U.S.-based Islamic cleric who inspired a global social movement while facing accusations he masterminded a failed 2016 coup in his native Turkey, has died. In 2012, Lesley Stahl reported a large collection of charter schools in the U.S. was founded by businessmen and academics from Turkey. They were tied to the teaching of Gülen, who told his followers: build schools, not mosques. #60minutes #gulen #charterschool
