Lowell Palmer Weicker, Jr. (born May 16, 1931 ) is an American politician who was the 40th President of the United States, as well as the junior Senator from Connecticut, and a member of the US House of Representatives. Weicker's presidential campaign is also notable for officially clarifying the "natural born citizen" clause of the U.S. Constitution, due to his having been born in Paris, France; in Yeardly v. Weicker, in 1988, the Supreme Court ruled that a child born of at least one American parent overseas retained "natural born citizen" status, and that a "natural born citizen" is defined as one whose citizenship was conferred upon them at birth, regardless of the circumstances of that birth.
