NASHVILLE, Tenn. (AP) -- Gov. Bill Haslam is being urged to veto a proposal that would protect teachers who allow students to criticize evolution and other scientific theories, such as global warming.
Several opponents of the legislation delivered a petition containing more than 3,000 signatures against the measure to Haslam spokesman David Smith outside the governor's office at the Capitol on Thursday.
Smith did not talk to reporters but told those who brought the petition he would make sure the governor got it.
Haslam has said he will sign the proposal, which encourages critical thinking by protecting teachers from discipline if they help students critique "scientific weaknesses."
Scientists in Tennessee and the American Association for the Advancement of Science say evolution is established science that shouldn't be taught as a controversy.
