. . . the Framers intended the Emoluments Clause to protect the republican character of American political institutions. "One of the weak sides of republics, among their numerous advantages, is that they afford too easy an inlet to foreign corruption." The Federalist No. 22 (Alexander Hamilton). The delegates at the Constitutional Convention specifically designed the clause as an antidote to potentially corrupting foreign practices of a kind that the Framers had observed during the period of the Confederation. Louis XVI had the custom of presenting expensive gifts to departing ministers who had signed treaties with France, including American diplomats. In 1780, the King gave Arthur Lee a portrait of the King set in diamonds above a gold snuff box; and in 1785, he gave Benjamin Franklin a similar miniature portrait, also set in diamonds. Likewise, the King of Spain presented John Jay (during negotiations with Spain) with the gift of a horse. All these gifts were reported to Congress, which in each case accorded permission to the recipients to accept them. Wary, however, of the possibility that such gestures might unduly influence American officials in their dealings with foreign states, the Framers institutionalized the practice of requiring the consent of Congress before one could accept "any present, Emolument, Office, or Title, of any kind whatever, from...[a] foreign State."
(. . .) St. George Tucker's explanation of the clause noted that "in the reign of Charles the econd of England, that prince, and almost all his officers of state were either actual pensioners of the court of France, or supposed to be under its influence, directly, or indirectly, from that cause. The reign of that monarch has been, accordingly, proverbially disgraceful to his memory." As these remarks imply, the clause was directed not merely at American diplomats serving abroad, but more generally at officials throughout the federal government.
