FILE - In this file photo of Jan. 17, 2013, Yoko Ono, left, and her son Sean Lennon visit a fracking site in Franklin Forks, Pa., during a bus tour of natural-gas drilling sites in northeastern Pennsylvania. Ono and Lennon have formed a group called “Artists Against Fracking,” which has become the main celebrity driven anti-fracking organization. A formal complaint filed with New York’s lobbying board asks it to investigate whether Artists Against Fracking is violating the state's lobbying law, according to the document obtained by The Associated Press.
