U.S. Senator John Boozman (R-AR) led a bipartisan letter to Commerce Secretary Wilbur Ross asking the administration to conduct a robust economic analysis to evaluate how any changes to NAFTA would affect changes to the nation’s crop and livestock sectors.

The letter noted that “it is imperative that before any changes are made to NAFTA, or any other free trade agreement, that economic analysis that illustrates the impact on the full supply chain of the industries involved be shared. As such, we request an economic analysis that examines and evaluates the impacts to crop and livestock sectors as a result of any change to NAFTA.”
