Rep. Denny Rehberg (R-MT) introduced legislation to require the U.S. Treasury Department to “mark livestock” imported into the U.S. He says federal law requires imports be “branded or marked with their country of origin, but the Treasury Department has for years exempted livestock under its so-called ‘J list’ of imports that are excluded from the branding provisions of the Tariff Act of 1930.” The proposed legislation would prevent Treasury from exempting livestock.
