Mississippi Gov. Phil Bryant has signed a bill that allows prayers led by students over school intercoms, at graduations, or at sporting events.
The new law says all Mississippi school districts must adopt a policy that lets students express their religious beliefs at various school events.
"We believe that we're on firm ground here with our opportunity for religious expression in a limited forum within public schools," Bryant said Thursday. "That does not mean that they won't file a lawsuit, and we'll see how that comes out for us."
The policy must include a disclaimer that the student's views are not endorsed by the school district.
The American Civil Liberties Union said the measure is likely to prompt a lawsuit. The measure becomes law by July.
