Trump joins Canada and Mexico leaders to sign new trade pact
President Donald Trump joined the leaders of Canada and Mexico at a global meeting in Argentina on Friday to sign a revised North American trade pact that he called "ground-breaking" and a benefit for "working people. The U.S.-Mexico-Canada Agreement is meant to replace the 24-year-old North American Free Trade Agreement, which Trump has long denigrated as a "disaster". He appeared with Canadian Prime Minister Justin Trudeau and outgoing Mexican President Enrique Pena Nieto at the Group of 20 nations summit in Buenos Aires for the formal signing ceremony. Each country's legislature must also approve the agreement.
