The North American Free Trade Agreement (NAFTA) is of topic today being the deadline set where House Speaker Paul Ryan.
Lighthizer said he would continue to work toward "the best possible deal for American farmers, ranchers, workers, and businesses". But that could be politically damaging: The trade agreement benefits Republican-held states where agriculture is a big business, since Mexico and Canada are big buyers.
Negotiators from the U.S., Mexico and Canada have nothing to show for their efforts despite meeting all week in Washington DC to coming up with a deal, knowing that time was running short to get a deal through Congress in this legislative session.

That is if the Trump administration wants Congress to consider an updated NAFTA before the end of 2018. The U.S. International Trade Commission then has up to 105 days after the signing to produce a study on the effects of the agreement.
