NAFTA

Congress is turning its attention to trade this week.

The Trans-Pacific Partnership would include 12 countries and 40 percent of the world's economy.

Two decades after its passage, the debate continues over the trade pact among the US, Mexico and Canada.

Exports from big states like Texas, California and Michigan have soared since the 1990s when the North American Free Trade Agreement opened U.S. markets to Mexico. But not every state has been as savvy promoting cross-border trade.

It's been 20 years since NAFTA was signed. These days, the mantra is that more manufacturing plants in Mexico should be good for the U.S.

In 1992, the North American Free Trade Agreement (NAFTA) was signed. In the two decades since, the number of people living illegally in the U.S. has nearly quadrupled.
