"This Constitution, and the Laws of the United States which shall be made in Pursuance thereof; and all Treaties made, or which shall be made, under the Authority of the United States, shall be the supreme Law of the Land; and the Judges in every State shall be bound thereby, any Thing in the Constitution or Laws of any State to the Contrary notwithstanding."

-the Laws of the U.S. (current, and future ones),
-Treaties that have been made or that will be made - 

Are what make up the Supreme Law of the Land.
