Tennessee Governor Bill Haslam says he may sign a proposal critics deride as the "monkey bill" for once again attacking evolution. The measure would protect teachers who allow students to criticize scientific theories like evolution. It’s headed to the governor after passing the Senate last month and the House last year. When asked by a reporter Monday if he's leaning toward signing the measure, Haslam said "probably so." Haslam says he's talked with the State Board of Education about whether the bill will affect the current curriculum and what's being taught in schools regarding evolution. Haslam says he was told it won't. Critics believe the proposal could possibly open the door for some religious teachings.
