The Supreme Court could rule Monday on whether Ten Commandments displays are permissible on government property.
Opponents challenging a monument on the Texas Capitol grounds and Ten Commandments displays in Kentucky courthouses say they're an unconstitutional government endorsement of religion.
In 2003, Roy Moore was removed from office as Alabama's chief justice when he refused to obey a federal judge's order to remove a Ten Commandments monument from the foyer of the Alabama Judicial Building.
Defenders respond that such displays, including engravings in the Supreme Court's own building, don't establish religion but merely acknowledge the nation's legal heritage.
The justices' ruling could affect thousands of Ten Commandments monuments and displays nationwide.
