Washington – US President Donald Trump’s administration formally notified Congress on Wednesday of its intent to renegotiate the three-nation North American Free Trade Agreement.

The talks with Canada and Mexico will begin “no earlier than August 16, 2017,” US Trade Representative Robert Lighthizer said in a statement.

During the 90-day countdown, USTR will consult with “Congress and American stakeholders to create an agreement that advances the interests of America’s workers, farmers, ranchers, and businesses,” he said.

Lighthizer said reforming the trade agreement, which Trump vowed to scrap altogether during his presidential campaign, fulfills a key promise to voters.

Trump’s charge that NAFTA and trade deals generally had cost American jobs gained him support among working class voters, who helped lift him to the White House.
