A Christian pastor from California has been freed from China after nearly 20 years behind bars and is back home in the U.S., the State Department said. Two groups say the 68-year-old David Lin was detained after he entered China in 2006, convicted of contract fraud and sentenced to life in prison. (AP Photo/Charles Dharapak, File)
