 Oklahoma public schools must now give Bible lessons in class. More from ABC's Jim Ryan. Starting immediately, says Oklahoma State Superintendent Ryan Walters, students from 5th through 11th grade will be taught from Christian scripture. It is academic malpractice not to be teaching the Bible's influence on American history. Oklahoma's Attorney General says having the Bible in schools is not against state law. He has not determined whether educators can be forced to teach from it. ABC's Jim Ryan reporting.
