House Democrats and the Trump Administration are on the verge of coming to an agreement on the updated NAFTA deal, the United States–Mexico–Canada Agreement (USMCA), however the timeline for an agreement to be reached by the end of the year is looking more and more formidable.
Despite Congress extending its legislative schedule by one week until December 20th, the window for coming to an on-time agreement is extremely tight because once an agreement is reached, ratifying a trade deal requires a series of timely procedural steps laid out in the 2015 trade promotion law. The more likely scenario is that a deal between the Democrats and the White House is announced before the end of the year, but the agreement will not be technically ratified until 2020.
