President Donald Trump's promises of mass deportations, which could bring batches of new arrivals fresh off the border bridges into Juárez, has Mexican law enforcement preparing to keep watch for potential trouble.

Mexican President Claudia Sheinbaum is pulling out all the stops to support the roughly 5 million undocumented Mexicans living in the U.S.

The flurry of attempted illegal crossing along the U.S.-Mexico border comes just 72 hours before Trump's inauguration. Border Patrol agents dissuaded and easily rounded the few migrants to face criminal charges of illegally entering the U.S.

Residents along Arizona's 372-mile border with Mexico make up a complicated tapestry of views, concerns and hopes on the eve of Trump's inauguration.

President Claudia Sheinbaum is detaining more migrants, seizing more fentanyl and positioning her country as a key ally against China. But the U.S. stance has shifted, too.

The Sheinbaum administration is gathering data to argue against tariffs, emphasizing their potential to harm U.S. economic growth and inflation.

United States Customs and Border Protection agents put up barricades on the Paso del Norte International Bridge that connects Mexico's Ciudad Juarez with El Paso, Texas. The barbed wire fencing is placed on the border as part of security exercises ahead of Donald Trump taking office for a second term as US president on January 20.
