TO THE MEMBERS OF THE UNITED STATES SENATE: The U.S. Chamber of Commerce strongly supports S. 746, the “Trade Security Act,” introduced by Senators Rob Portman and Dianne Feinstein. This bipartisan legislation would help restore the proper constitutional role of Congress in tariff policy by providing for Congressional disapproval of prospective tariffs designated under Section 232 of the Trade Expansion Act of 1962. Members who cosponsor this legislation will receive credit for the Leadership component of their “How They Voted,” rating. Prior application of Section 232 tariffs has inflicted substantial harm on U.S. workers and consumers in every state, raising costs for U.S. manufacturers and eliciting foreign retaliation that has depressed American industrial and agricultural exports. The imposition of these tariffs on many of America’s closest allies—on the argument that their exports threaten U.S. national security—has also undermined U.S. efforts to build an international coalition of like-minded countries to combat the use of unfair trade practices.
