The momentum to impeach in Washington, D.C., is not only hurtling Congress and President Donald Trump toward a potential constitutional crisis, but the prospect of reaching a solution to the ongoing trade standoffs has dimmed considerably.

That’s the opinion of leading international trade lawyer Clifford Sosnow, who notes the time frame for passing the U.S.-Mexico-Canada Agreement (USMCA)—and thereby revamping the North America Free Trade Agreement (NAFTA)—is growing shorter by the day, denting plans for global companies that rely heavily on exports.

“With impeachment officially on the table and the hyper-partisan climate in the lead-up to next year’s elections, there is serious concern whether the USMCA is dead in the water,” says Sosnow, an Ottawa-based partner with Canadian law firm Fasken.

“It’s unclear how much of a window is even left for approval of the USMCA. There are also high odds of failure post-election, especially if the Democrats win. The party has not shown any enthusiasm for the USMCA in its current form.”

Sosnow is not shooting from the hip in an easy chair. He has appeared before NAFTA and WTO panels and the Canadian International Trade Tribunal, and he has numerous clients affected by tariffs as well as any decisions on NAFTA, including automobile manufacturers, banks, service companies, IT companies, large retailers, manufacturers, agriculture business, aerospace firms, and transportation companies.
