WASHINGTON – President Donald Trump hailed his revamped North American trade agreement with Canada and Mexico as a breakthrough for U.S. workers on Monday, vowing to sign it by late November. But it still faces a lengthy path to congressional approval after serving for two decades as a political football for American manufacturing woes. Embracing the U.S.-Mexico-Canada Agreement, which the Canadians joined just before a Sunday midnight deadline, Trump branded it the “USMCA,” a moniker he said would replace the 24-year-old North American Free Trade Agreement, or NAFTA.
