I got curious about laws and my very cursory search reveals:
There's no law regarding strict separation of Church and State, but legal precedent says that the State shall endorse no one religion over another. District Courts have refused the right of a coach to even sit in on a student-led prayer, much less lead one (Borden v. School District of the Township of East Brunswick) and his appeal of this decision was denied by the Supreme Court.
I'd search for more law and precedent because I think it's interesting, but I'm tired and going to go nap, lol.
