Texas will require all public school classrooms to display the Ten Commandments under a new law that will make the state the nation’s largest to attempt to impose such a mandate.

Gov. Greg Abbott announced Saturday that he signed the bill, which is expected to draw a legal challenge from critics who consider it an unconstitutional violation of the separation of church and state.

A similar law in Louisiana was blocked when a federal appeals court ruled Friday that it was unconstitutional. Arkansas also has a similar law that has been challenged in federal court.
