The Separation of Church and State clause is up for debate again in the Supreme Court.
This battle for religious freedom will have a significant impact on national parks and monuments. The latest manifestation in this ongoing fight is over a memorial to those who died in World War One in the shape of a cross on a public park. The plaintiffs argue that since the location is under government control, the monument violates the separation of church and state.
The outcome would affect similar statues across the country.
