In the epicurean world, Northern California is famous for two intoxicants — wine and weed. With recreational marijuana about to be legal in the Golden State, some cannabis entrepreneurs are looking to the wine industry as a model.

On the elegant terrace of a winery overlooking the vineyard-covered hills of Sonoma County, north of San Francisco, a dozen invited guests are sipping pinot noir, nibbling hors d'oeuvres and taking hits off a water pipe.

Two-thousand miles away from the Supreme Court's vaulted ceiling and marble friezes, 60-year-old jobless mother Maria Guereca sat in her $20-a-month, one-room apartment with a fan and a hotplate — beside a picture of her dead son.

On Monday, the Court gave Guereca, who lives in Juarez, Mexico, a partial victory, saying a lower court erred in granting immunity to an agent who shot and killed her son.

Can the family of a slain Mexican teenager sue the federal agent who shot him across the U.S.-Mexico border for damages? The U.S. Supreme Court did not answer this question on Monday, instead opting to send a case back to a lower court.

The case centers on a larger question: whether the Constitution extends protection to an individual who is killed on foreign soil, even though that person is standing just a few yards outside the United States.

Donkeys have been loyal beasts of burden for 5,000 years, yet they still don't get a lot of respect.

In the wild, burro herds are a nuisance. In captivity, they can be mistreated. But in recent years, donkey sanctuaries have sprung up across the country. The largest among them is Peaceful Valley Donkey Rescue, outside of San Angelo, Texas, where the air periodically erupts with the unpeaceable sounds of donkey braying.

The number of people apprehended while trying to cross the Southwest border illegally has plummeted, as the age-old practice of hopping the border without papers has changed profoundly in recent months.

One human smuggler, who gives his first name as Orlando, said his business is worse than he's ever seen it. He blames the Trump administration's increased emphasis on border security and enforcement of federal immigration laws.

Jason Cisneroz, a community service officer in Houston, is troubled. His job in the nation's fourth largest city is to forge good relations between the police and Hispanic immigrants, a population typically wary of blue uniforms.

"A couple of days ago there was a witness to a burglary of a motor vehicle," he said. "She saw the suspects run to a certain place and with items they stole from a car, but she was afraid to come to police, she was in fear they would ask for her papers."

After making the need for a wall along the U.S.-Mexico border a central campaign theme, President Trump has asked Congress for just $1.6 billion to start building 74 miles of barriers. Texas alone shares more than 1,200 miles of border with Mexico.

If Congress approves the current request, 14 miles of old fencing in the San Diego sector would be replaced, and 60 miles of new structures would be built in the Rio Grande Valley of Texas — the region with the heaviest illegal traffic.

A new Texas law banning sanctuary cities has outraged Democrats, immigrant advocates and police chiefs. Joining the opposition is a tiny, defiant city on the Mexican border.

El Cenizo is a city that fought for its very existence. It's all of half a square mile, located on the twisting Rio Grande just east of Laredo. It has fewer than 4,000 residents and only eight city employees.

Of all the wild places along the U.S.-Mexico border, Big Bend National Park, named for the great curve of the Rio Grande, is the gem.

In Santa Elena Canyon in west Texas, the international river flows between 1,500-foot-tall sheer walls of limestone — a study in light, shadow, water and time.

The Big Bend region — where the ghostly Chisos Mountains rise out of the prickly Chihuahuan Desert — is sacred ground. As writer Marion Winik described, it's "what I imagine the mind of God looks like."

After months of bashing the North American Free Trade Agreement and threatening to pull out of it, President Trump today said he'll begin renegotiating with Canada and Mexico.

As the White House pushes Congress to fund President Trump's U.S.-Mexico border wall, a new wrinkle has emerged that could stymie parts of the massive project.

There's a lot of excitement at the Border Security Expo in San Antonio, where vendors schmooze with government buyers and peddle their wares.
