Pat Toomey gave a speech at the American Enterprise Institute in opposition to the proposed United States Mexico and Canada (USMCA) Trade Agreement that would replace the North American Free Trade Agreement (NAFTA), arguing that it is unnecessary and would negatively impact his home state of Pennsylvania. Toomey argued that NAFTA is a good agreement and dismissed suggestions that the USMCA is a better replacement, suggesting incremental changes to the existing NAFTA agreement instead of a whole scale rewrite.
