who must approve any treaties that are made with foreign countries
Treaty Clause The Treaty Clause is part of Article II, Section 2, Clause 2, of the United States Constitution, that empowers the President of the United States to propose and chiefly negotiate agreements between the United States and other countries, which, upon receiving the advice and consent of a two-thirds supermajority vote of the United States Senate, become treaties under international law.
Treaty Clause Additionally, an international accord that is inconsistent with the U.S. Constitution is void under domestic U.S. law, the same as any other federal law in conflict with the Constitution. This principle was most clearly established in the case of Reid v. Covert.[9] The Supreme Court could rule an Article II treaty provision to be unconstitutional and void under domestic law, although it has not yet done so.
