With increased success comes increased scrutiny, Turkey's powerful Gulen movement is learning. Over the years, the movement -- founded by the charismatic Islamic theologian Fetullah Gulen, who currently resides in Pennsylvania -- has been able to build what is thought to be the largest public charter school program in the United States, with more than 120 schools across the country that receive hundreds of millions of dollars in taxpayer money. (The movement also runs a very successful schools program in Turkey.)
Lately, though, the Gulen schools in the US have been coming under increased media scrutiny, facing questions not so much about the quality of education they offer, but rather about violations of financial, legal and ethical standards. One of the first major pieces to take a hard look at how the Gulen charter schools operate came in March of last year in the Philadelphia Inquirer, which claimed that federal authorities were investigating several of the movement's schools for violating immigration laws and for forcing employees to send part of their paycheck back to Turkey.
