The number of migrants caught illegally crossing the U.S. borders with Mexico and Canada fell in November, a senior U.S. border official told Reuters, part of a months-long trend that undercuts President-elect Donald Trump's claim illegal immigration is out of control.

President-elect Donald Trump promised to impose a 25% tariff on all goods from Mexico and Canada on his first day in office. Imports from Mexico and Canada totaled $900 billion in 2023. Trump has proposed tariffs as a solution to government funding.

The president-elect’s opening salvo in trade and border talks with the United States’ neighbors is casting a harsh light on the North American alliance.
