The National Motto of the United States of America, is In God We Trust it was established in a 1956 law signed by President Dwight D Eisenhower. "It is engraved in stone in the House of Representatives in our Capitol and it is printed on our currency. If it is appropriate for our motto to be inscribed in the halls of our highest level of Government, then it is certainly appropriate to display it on the walls of our schools. God is in our pledge, our National Anthem, nearly every patriotic song, and in our founding documents. We honor His birth, death, and resurrection as holidays, and we turn to Him in prayer in times of crisis."
