President Donald Trump is finding an unlikely ally in his efforts to overhaul the North American Free Trade Agreement: the political left.
Civil-society groups, union leaders and left-wing politicians have opposed almost everything Trump has done. But they’re urging him to stand firm in his attempt to overhaul Nafta -- and face down opposition from business groups, who complain that U.S. companies will be hurt by the proposed changes. Mexico and Canada have called U.S. demands unworkable, including on regional-content requirements for cars and investor-state dispute systems.
