The United States and Mexico have reached an agreement to change parts of NAFTA, the trade deal that President Donald Trump has derided for years as unfair. Trump announced the agreement from the Oval Office Monday. But the deal left open the question of whether Canada, the third country in NAFTA, would agree to the changes. Much of the business world has been worried about Trump's trade policies, and the stock market reacted positively to the news of a deal. The Dow closed nearly 260 points higher on Monday.
