President Trump has signaled he'll take a tougher approach to immigration after the resignation of Homeland Security Secretary Kirstjen Nielsen and as migrant families continue to cross the border.

Migrants from Central America who end up in the U.S. must cross the Guatemala-Mexico border, where immigration control is light to nonexistent. Quicker journeys are spurring more illegal immigration.

Central Americans streaming across the U.S.-Mexico border are traveling along well established smuggling routes through Mexico. Gracias a Dios, Guatemala, has become a busy smuggling staging area.

At Mexico's southern border, migrants can cross over from Guatemala for a price. The U.S. threatens to close its border unless Mexico slows migrants' travels. Many make their way to El Paso, Texas.

The Trump administration is sounding the alarm about "fake families" amid a surge of Central Americans crossing the southern border. Immigrant advocates say they're just trying to make it to the U.S.

The Trump administration is warning of "fake families" and fraudulent documents amid the surge of families at the U.S.-Mexico border.

The Border Patrol is bringing in more agents and asking the Pentagon for help as thousands of migrants continue to cross the U.S.-Mexico border each day.

El Paso is the new illegal crossing hot spot on the southern border. Officials say they have run out of room to process migrants, and they're encountering more and more infectious diseases.

Jose Eduardo was separated from his daughter Yaimy after crossing the U.S.-Mexico border last spring. He was deported, but his daughter remained in U.S. custody. Now, he has returned to find her.

The system is "overwhelmed," says Manuel Padilla, director of Joint Task Force-West. The migrants apprehended at the Southern border in February made for the highest monthly total in almost a decade.

Agents apprehended some 60,000 people last month — about 12,000 more immigrants than they picked up in January. The majority arrested are families, and children traveling alone or without a parent.

Eight steel-and-concrete mock-ups of border wall prototypes were put up near the San Diego-Tijuana border in 2017. They were supposed to represent the "next generation" of border barriers.

Thousands of unaccompanied migrant children have reported being sexually abused while in U.S. government custody. The numbers were detailed in documents released by a Democratic congressman.

In two-thirds of over 1,500 cases from April 2016 to February 2018, Immigration and Customs Enforcement put migrant youth into detention when they turned 18, according to government data.

A temporary shelter has been contracted south of Miami to house more than 2,000 migrant children. It is the nation's only corporate, for-profit migrant youth shelter.

Hundreds of migrant children are housed at a South Florida shelter, which is under scrutiny because it's the only one to be run by a for-profit corporation and is not overseen by state regulators.

Over 10,000 immigrant children are in U.S. custody. In the past year, lawyers say at least 170 willing sponsors were arrested and put in deportation proceedings after coming forward for the child.

The Trump administration is using a system that is meant to help migrant children to deport the kids and their families, according to several lawsuits filed around the country.

President Trump proposed a deal to congressional Democrats that would protect recipients of the Deferred Action for Childhood Arrivals program in exchange for $5.7 billion to fund the border wall.

Before family separation became an official and controversial policy of the Trump administration, federal immigration agents separated "thousands" of migrant children from their parents.
