Multinational corporations pressing Congress to adopt an updated version of the North America Free Trade Agreement shed over half a million U.S. jobs for trade-related reasons since NAFTA took effect, according to a new analysis of government data.

The analysis, conducted by Public Citizen’s Global Trade Watch, a liberal nonprofit critical of recent trade agreements, found that 182 U.S. companies pushing for “NAFTA 2.0” ― either directly or through groups representing them ― had outsourced 225,527 jobs to countries with cheaper labor since 1994. The companies lost 284,489 more jobs due to heightened competition from cheaper foreign imports or other unspecified trade-related reasons, Public Citizen concluded.

Public Citizen’s research aims to cast doubt on President Donald Trump’s contention that the revised trade agreement he negotiated, officially known as the United States-Mexico-Canada Agreement, or USMCA, fixes the flaws in NAFTA that cost American workers jobs.

“Having corporate coalitions packed with chronic outsourcers of American jobs spending millions to pass NAFTA 2.0 certainly eviscerates Trump’s claim to have replaced NAFTA with a totally different deal that is good for working people,” said Lori Wallach, director of Public Citizen’s Global Trade Watch.

Public Citizen identified 90 companies that are members of either the USMCA Coalition, a group convened by the U.S. Chamber of Commerce and other big business coalitions, or the Pass USMCA Coalition, which has taken the lead on public efforts. Pass USMCA is run by former Trump deputy chief of staff Rick Dearborn and co-chaired by former Rep. Joe Crowley (D-N.Y.) and former Obama administration Commerce Secretary Gary Locke.

Public Citizen counted an additional 92 companies that belong to business trade groups like the Business Roundtable, the National Association of Manufacturers or the U.S. Council for International Business, which are members of either or both pro-USMCA coalitions.

The nonprofit then looked at the number of trade-related job losses the companies reported to the federal government as part of the Department of Labor’s Trade Adjustment Assistance program, which provides educational benefits to workers displaced by trade agreements.

The companies in the group that outsourced the most jobs were V.F. Corp., which makes clothing brands including Timberland and Vans; the automotive parts manufacturer Delphi; General Electric; General Motors; and Hewlett Packard.

Spokespeople for the USMCA Coalition, as well as V.F. Corp. and Delphi, did not immediately respond to requests for comment on Public Citizen’s analysis.
