Oklahoma schools head takes aim at Tulsa district. Critics say his motives are politically driven

In his first year as head of Oklahoma's public schools, State Superintendent Ryan Walters has taken on what he describes as “radical leftists" indoctrinating students. Now, the Republican who has fully embraced so-called culture war issues has a new target in his sights: Tulsa Public Schools, which is Oklahoma's largest school district and has a student body of more than 33,000 students, nearly 80% of whom aren't white.
