            States against all enemies, foreign and domestic; that I 
            will bear true faith and allegiance to the same; that I take 
            this obligation freely, without any mental reservation or 
            purpose of evasion; and that I will well and faithfully 
            discharge the duties of the office on which I am about to 
            enter: So help me God.'' (5 U.S.C. 3331.)
