President Trump has promised to build a wall along the 2,000 miles of the U.S.-Mexico border.

A third of that border already has a barrier, thanks to the Secure Fence Act of 2006, which was signed by then-President George W. Bush. That initiative ran into issues with landowners near the Rio Grande. If the wall goes forward as Trump promises, more lawsuits may be coming.

Donald Trump talked a lot about building a wall between the U.S. and Mexico when he was a candidate. Now that he is president, it's unclear just what that wall is going to look like and when it might get built.

What we know so far is that it's likely to be a fence, not a wall, it won't extend the length of the border and it will be very unpopular with its southern neighbor.

At the moment, about a third of the 2,000-mile border with Mexico is fenced. Some parts are 10 feet tall, some are 20 feet, some are wire mesh, some are steel beams.

The morning of Oct. 18, 2016, the employees at La Divina, a taqueria and Mexican grocery in Buffalo, N.Y., were prepping for the lunch crowd — making salsa, grilling chicken and stocking the shelves with Mexican Cokes and Corona beer. Suddenly, agents from Homeland Security Investigations rushed in.

With President-elect Donald Trump's tough talk on immigration, private prisons may be an early winner under his administration.

In the week after Election Day, stocks of GEO and CoreCivic, the two biggest for-profit detention companies, shot up more than 20 and 40 percent, respectively.

Last spring at a town hall meeting on MSNBC, Trump said this about the confinement industry: "By the way, with prisons I do think we can do a lot of privatizations and private prisons. It seems to work a lot better."

Every year in late November, the New Mexican village of Abiquiu, about an hour northwest of Santa Fe, celebrates the town saint, Santo Tomas. Townfolk file into the beautiful old adobe Catholic church to pay homage its namesake.

But this is no ordinary saint's day. Dancers at the front of the church are dressed in feathers, face paint and ankle bells that honor their forebears — captive Indian slaves called genizaros.

He is known only as Case 0408. The remains of a middle-aged male immigrant were discovered in Jim Hogg County, Texas, on Nov. 3, 2009. Six belongings are the only things in the universe that may help identify him: a beat-up sneaker, a size L pullover shirt and hoodie, a ring found sewn into the waistband of his pants, a red and black lucha libre wrestler's mask, and a stuffed smiley lion.

Edit note: This report includes some graphic scenes.

The Aryan Brotherhood of Texas originated in prison in the early 1980s as a protection racket for white inmates, but as the tattooed gang members were released into the free world, they became one of the most violent crime syndicates in America.

Two years ago, the Justice Department trumpeted that it had "decapitated" the leadership of the Aryan Brotherhood of Texas, or ABT. Seventy-three gang members were convicted, including all five regional generals.

On Oct. 2, 1835, a small group of rebellious colonists in what is now South Texas defied Mexican rule with the memorable battle cry: "Come and take it!" The dare referred to a small brass cannon, but it became a declaration of Texas' independence and grit as famous as "Remember the Alamo." Today, you can see a twist of the historic slogan on the Come and Wash It Laundromat and Come and Style It beauty salon, both in the town of Gonzales.

A group of inmates in Texas is suing the state prison system, the nation's largest, arguing that extreme heat is killing older and infirm convicts. The inmates allege it constitutes "cruel and unusual punishment" and they're asking the courts for relief.

It's no wonder that in Texas, home to the largest prison system in the nation and the busiest death chamber in the developed world, there's a museum about its prisons.

To find it just look for the sign with the ball and chain on Interstate 45, north of Houston.

Jim Willett, the Texas Prison Museum director, is not your typical museum docent. His deep knowledge of the artifacts of state-ordered punishment comes from the years he oversaw the looming, red-brick penitentiary in downtown Huntsville known as The Walls.

Polls show that the idea of building a wall across the southern border remains unpopular with the general public and especially in the U.S. borderlands.

But not everyone living near the international divide opposes a barrier between the U.S. and Mexico. Donald Trump has a small, zealous following along the southern frontier.

If you watch a watermelon harvest you may never think about the pink summery fruit again the same way.

Two pickers walk the rows. They bend over and grab the 20-pound gourds and pitch them to a man perched on the side of a dump truck, who heaves them up to another catcher in the truck bed. The pickers have arms like Popeye and the timing of acrobats. They like this crop because the bigger the melons the more they can earn.

The calculated killing of five uniformed officers would be traumatic for any metropolitan police department in America, but it has fallen especially hard in Dallas, where the police force already suffers from low pay and poor morale.

Citizens in Dallas are rallying around their officers in blue, suggesting the events could be a turning point for the embattled department.

Women who want an abortion in deeply conservative Texas have slightly more choice these days than they had a few months ago. In March, the Food and Drug Administration simplified rules on abortion medication, allowing patients to take the standard regimen of abortion drugs later in a pregnancy.

Immigrants fleeing gang violence in Central America are again surging across the U.S.-Mexico border, approaching the numbers that created an immigration crisis in the summer of 2014. While the flow of immigrants slowed for much of last year, nothing the U.S. government does seems to deter the current wave of travelers.
