First Liberty Institute sent a letter to officials at the KIPP Antioch College Prep Elementary School in Nashville, TN on behalf of Eric Rivera, a former first grade teacher, demanding that the school clear his record and adopt policies that ensure teachers are accommodated after he was reassigned for refusing to read two books to first graders that promote same-sex marriage. The letter also asks the school to ensure that parents are notified when topics of sexuality are going to be discussed.
