Oklahoma school districts are responding after State Superintendent Ryan Walters sent district superintendents across the state a video that he said must be shown in classrooms.

Oklahoma State Superintendent Ryan Walters did not reject the idea of a national mandate to require Bibles in schools on Tuesday night when asked if he would implement the policy if selected as the next education secretary.

Republican President-elect Donald Trump is quickly filling out his incoming Cabinet, and Walters’ name has been mentioned by some national news outlets as a potential pick for education secretary or adviser.
