NAFTA and the United States-Mexico-Canada Agreement (USMCA) [Updated March 2, 2020] [open pdf - 2MB]
From the Document: "The 116th Congress, in both its legislative and oversight capacities, has been active in numerous trade policy issues related to renegotiation of the North American Free Trade Agreement (NAFTA) and its replacement, the United States-Mexico-Canada Agreement (USMCA). In May 2017, the Trump Administration sent a 90-day notification to Congress of its intent to begin talks with Canada and Mexico to renegotiate and modernize NAFTA, as required by the 2015 Trade Promotion Authority (TPA). Negotiations officially began on August 16, 2017, and were concluded on September 30, 2018. The USMCA was signed on November 30, 2018. The agreement was approved by the House of Representatives (H.R. 5430) on December 19, 2019, by a vote of 385-41, and by the Senate (S. 3052) on January 16, 2020, by a vote of 89-10. President Trump signed the USMCA implementing legislation on January 29, 2020 (P.L. 116-113). All three parties must ratify the agreement and have regulations and laws in effect to meet their USMCA commitments before the agreement enters into force."
