On March 1, 2019, many organizations representing the agricultural sector in the United States announced their support for the USMCA and asked Congress to ratify the agreement. They also called on the Trump administration to continue to support NAFTA until the new trade agreement is ratified.  On March 4, House Ways and Means President Richard Neal predicted a “very hard” path through Congress for the agreement.  Starting March 7, senior White House officials met with members of the Ways and Means House of Representatives, as well as moderate cackles from both parties, such as the Solver Caucus, the Tuesday Group and the Blue Dog Coalition, to seek ratification support. The Trump administration also withdrew from the threat to withdraw from NAFTA as negotiations with Congress continued.  Fox News reported on December 9, 2019 that negotiators from the three countries reached an agreement on implementation, paving the way for a final agreement within 24 hours and ratification by all three parties before the end of the year. Mexico has agreed to impose a minimum wage of $16 per hour for Mexican auto workers by a “neutral” third party. Mexico, which imports all of its aluminum, also objected to the provisions relating to the U.S. steel and aluminum content of automotive components.  Canada and the United States have also agreed on strict rules to ensure fair and transparent management of tariff quotas to ensure that distributors can use them fully.
Growing objections within Member States to U.S. trade policy and various aspects of the USMCA have had an impact on the signing and ratification process. Mexico said it would not sign the USMCA if tariffs on steel and aluminum were maintained.  Based on the results of the November 6, 2018 U.S. election, it has been speculated that the greater power of Democrats in the House of Representatives could jeopardize the passage of the USMCA agreement.   Bill Pascrell, a senior Democrat, argued for changes to the USMCA to pass Congress.  Republicans have opposed the USMCA provisions that impose labour rights on LGBTQ and pregnant workers.  Forty Republicans in Congress have asked Mr. Trump not to sign an agreement that includes “the unprecedented integration of sexual orientation and the language of gender identity.” As a result, Trump ultimately signed a revised version that required each nation only to “policies it deems appropriate to protect workers from discrimination in the workplace” and said the United States would not be required to introduce additional non-discrimination laws. The Canadian government expressed concern about the changes that have occurred under the USMCA agreement.  On April 3, 2020, the U.S. Department of Commerce (www.trade.gov/export-solutions) informed the United States and Mexico that it had completed its ratification process on the national territory.  President Donald Trump`s greatest trade performance, the U.S.-Mexico-Canada agreement, takes effect Wednesday, replaces NAFTA and ends its threat to disintegnch the free trade zone with three nations.
