Vice President Mike Pence says the renegotiated North American Free Trade Agreement is part of the President Trump’s “America First” agenda.

Pence was in Ankeny, Iowa, Tuesday afternoon, urging Iowans to lobby for passage of the trade pact.

Canada’s government has begun the process of ratifying the deal. In Mexico, passage requires majority support in Mexico’s senate. Once the Trump Administration formally submits the deal to Congress, the U.S. House and Senate have 30 days to either ratify or reject it.
