The Bricker Amendment is the collective name of a number of slightly different proposed amendments to the United States Constitution considered by the United States Senate in the 1950s. None of these amendments ever passed Congress. Each of them would require explicit congressional approval, especially for executive agreements that did not require the Senate's two-thirds approval for treaty. They are named for their sponsor, conservative Republican Senator John W. Bricker of Ohio, who distrusted the exclusive powers of the president to involve America beyond the wishes of Congress.
