On the recordMarch 6, 2003
the second-degree amendment that I offer today would add to the underlying Levin amendment a provision that would require the President to obtain the approval of two-thirds of the Senate before withdrawing from or extending this treaty. Mr. President, Article II, Section 2 of the Constitution states that the President ``shall have the Power, by and with the Advice and Consent of the Senate, to make Treaties, provided that two thirds of the Senators present concur. . . .'' The Senator from Michigan pointed out in his remarks that the Constitution is silent on the process by which the United States can withdraw from a treaty, and the record in the Congress and the executive branch is mixed. However, I believe and I think many others believe the intent of the Framers as explained by Thomas Jefferson is clear. In section 52 of Jefferson's Manual, he writes: Treaties are legislative acts. A treaty is the law of the land. It differs from other laws only as it must have the consent of a foreign nation, being but a contract with respect to that nation. Article II, Section 3 of the Constitution states that the President shall: take Care that the laws be faithfully executed. . . . Jefferson continues: Treaties being declared, equally with the laws of the United States, to be the supreme law of the land, it is understood that an act of the legislature alone can declare them infringed and rescinded.
