administrations

PHOENIX — For decades, all that separated the U.S. from Mexico was barbed wire.

Now, after a massive infusion of cash from Congress, President Trump’s administration is swiftly building what it has dubbed a “smart wall,” a combination of 30-foot-tall steel fencing and an array of sophisticated technology like sensors, cameras and towers allowing Border Patrol to surveil the territory.

The wall is under heavy scrutiny for the billions of dollars being dedicated to it when border crossings are at their lowest in decades. Critics say the U.S. is militarizing the border as it increasingly deploys sophisticated surveillance technology to the area, impacting local communities.

“We are seeing a massive expansion of surveillance and surveillance technology across the borderlands,” said Ricky Garza, border policy counsel at the Southern Border Communities Coalition, an advocacy group. “The wall in all its forms is harmful to communities.”

Officials say the technology is complementary to the physical wall and frees up agents for other tasks.

“It’s a smart wall. It’s not just a barrier,” Customs and Border Protection Commissioner Rodney Scott said during recent congressional testimony. “It maximizes the use of our most valuable resource, which is our agents.”

Contracts for hundreds of miles of wall already inked

The wall has been a top priority for Trump, a Republican, since he first ran for president.

During the administration of President Joe Biden, a Democrat, the border emerged as a flashpoint, with thousands of people seeking to cross into the country each day. Those numbers started to taper off shortly before Trump returned to office last year and then slowed to a trickle, with his broader immigration crackdown serving as a deterrent for would-be migrants.

Flush with $46 billion to finish the wall after an infusion by Congress for immigration enforcement, CBP is inking tens of billions of dollars in contracts to build the wall and push along the president’s signature project.

Homeland Security Secretary Markwayne Mullin said recently that a preliminary part of the wall will be finished by “this time next year.” Scott said his agency is putting up 6 miles of wall a week.

Hundreds of miles had already been built before Trump returned to office. As of mid-June 2026, CBP has erected another 74 miles and aims to build hundreds more. There is no wall planned for roughly 535 miles of the roughly 2,000-mile-long border, because rugged terrain already serves as a barrier. Ground sensors and towers will be used instead.

CBP is also going back to hundreds of miles of already built wall and adding more technology, lights and roads. Along the long stretches of river in Texas that mark the border with Mexico, they’re deploying 12- to 15-foot-long cylinder-shaped buoys meant to keep migrants or smugglers from crossing the border.

More technology being deployed on the border

Technology is playing a greater role in the Trump administration’s effort to make illegal crossings along the border more difficult, part of a broader transformation of CBP in the years since Sept. 11, 2001, into an intelligence operation with a mass surveillance network whose reach extends far beyond the nation’s frontiers, according to reporting by The Associated Press.

And critics say the border technology poses a threat.

The Southern Border Communities Coalition says surveillance technologies can push migrants into more dangerous routes to avoid being detected.

Garza, the group’s policy counsel, warned that surveillance technology infringes on the privacy rights of border residents and that locals have found ground sensors used to detect smuggler or migrant traffic placed on their property without their consent.

Nayda Alvarez and her relatives own land along the Rio Grande roughly 125 miles inland from the Gulf of Mexico. She has found cameras placed on her family’s land, and just last week she spotted a surveillance tower about a quarter of a mile down the river from her house.

“Are we expecting a war or something?” she said. “It doesn’t make me feel safer.”

Dave Maass, director of investigations for the Electronic Frontier Foundation, a nonprofit that focuses on civil liberties related to digital technology, said the technology has made the border area “a hostile environment” for locals and would-be migrants.

The foundation has published a guide on the various types of surveillance towers in use along the southern border designed to help local residents.

These can range from fixed towers with video, infrared and radar technologies that have a range of roughly 8 miles to remote video surveillance systems that have cameras and a spotlight fixed on top. Some are mounted on the backs of trucks so agents can drive them to different parts of the border.

Increasingly, these towers are autonomous. They can scan an area, analyze what they’re seeing using artificial intelligence and alert Border Patrol agents to something suspicious. Proponents say this helps keep Border Patrol agents out in the field instead of sitting in front of computer screens watching for activity. But it also increases AI decision-making along the border when experts have warned about the technology’s potential for bias or other problems.

The big GOP tax cuts and spending bill passed by Congress last summer requires that CBP buys only the autonomous towers, and the department is deploying an additional 95.

Underground, buried fiberoptic cables can sense movement, capturing data that is also then analyzed by AI.

“We follow the contour of the land. We go through trees. We go down into the river banks. We can go absolutely everywhere,” said Magnus McEwen-King, CEO of Sintela, which has a contract with CBP to install the cables. He spoke at a recent border security expo in Phoenix, where some of the technology was on display.

CBP also uses ground sensors and trail cameras to detect smuggling routes.

Concerns over cost and future plans

The nonpartisan watchdog group Taxpayers for Common Sense has questioned both the huge amounts of money for the wall-building and whether taxpayers are getting their money’s worth.

In 2011, under Democratic President Obama, Homeland Security Secretary Janet Napolitano pulled the plug on a project to build a “virtual wall” of integrated technology like radars, sensors and cameras across the entire border after it ran over budget, faced technological glitches and was behind schedule.

Josh Sewell, director of research and policy at Taxpayers for Common Sense, said the organization would like to see more “robust evaluation” of the technologies being used to avoid similar scenarios. And he criticized the Trump administration for lack of oversight on how the money is being spent, a charge CBP has denied, citing “oversight mechanism.”

In the Big Bend area of southern Texas, opposition to the department’s wall-building plans gathered strong bipartisan support especially in the most sensitive areas that run through a state and national park and a wildlife area.

CBP now says it is not planning to build a 30-foot-high bollard wall in those areas. Its recently announced plans include installing patrol roads and some barriers designed to stop cars and using detection technologies.

Clara Benson, who is one of the founders of the No Big Bend Wall coalition, says bright lights in the area designed to illuminate the border could pollute the skies in an area renowned for having some of the best views of the stars. Even without a 30-foot-tall steel wall running through the land, there is concern about CBP’s plans.

“There’s still a lot of fear and dread that the plan is still going to be quite damaging,” she said.

Just days after the Trump administration completed millions of dollars in renovations on the Lincoln Memorial Reflecting Pool to make it American flag-blue, residents and online users noted it had turned a phosphorescent green.

Here’s why:

The calm, still waters of the Reflecting Pool make it an ideal nursery for algae growth. Algae need nitrogen and phosphorus to grow, and the Reflecting Pool is primarily fed by the Potomac River, which gets heavy doses of those nutrients from nearby urban and agricultural lands.

The Potomac also absorbed one of the largest sewage spills in U.S. history earlier this year when a pipe burst five miles upstream of Washington, although that event probably happened too long ago to contribute to the algal bloom today.

Untreated sewage is high in nitrogen and phosphorus. When nutrient levels are high, feasting algae can quickly reproduce.

The Department of the Interior said when the algae first appeared that it was “residual,” from the supply lines to the pool.

Experts also speculate that the darker blue color may be helping the Reflecting Pool absorb more heat. The higher temperatures promote algae growth by allowing their metabolisms to shift into overdrive.

Summer temperatures in D.C. aren’t helping. This week, temperatures are as high as 95 degrees in the city, prompting a heat alert.

The combination probably explains the excessive growth, turning the water surface an opaque green and preventing onlookers from seeing the new blue hue of the concrete basin.

Algae are important and beneficial organisms when the ecosystem is in balance. They’re the base of the aquatic food chain, fed on by herbivores of all shapes and sizes, including shrimp and juvenile fish, which in turn feed organisms higher up the food chain. The single-celled organisms use the power of the sun to produce energy through photosynthesis, similar to houseplants on your balcony.

In an effort combat the algae in the Reflecting Pool, employees of the National Park Service were seen pouring in gallons of hydrogen peroxide, a chemical commonly used in pool maintenance.

The Department of the Interior also is employing a “high-tech nanobubble ozone technology” to destroy the cells of the algae.

Ozone — yes, the same irritant that is in smog — is a gas composed of three oxygen molecules, and the small size of the bubbles allow the most gas transfer into the water, where it can damage algal cells, similar to how it irritates our lungs.

This only treats the symptoms, however. Generally, ozone nanobubbling is effective as a temporary solution for algae blooms. Longer-term fixes would have to address what makes the Reflecting Pool so ideal for algae, such as its depth, darker color and inflow of nitrogen and phosphorus.

In California, ozone nanobubbles also have been used in a project to improve water quality in the Tijuana River. The 120-mile river that runs near the border in northern Mexico and Southern California was the site of a pilot study in 2025. The U.S. section of the International Boundary and Water Commission reported that the nanobubbling reduced “odors and bacteria,” but the project concluded prematurely after a flood swept some of the instrumentation into the river.

PROVIDENCE, R.I. — A federal judge has blocked the Trump administration’s sweeping demands for confidential transgender patient information from Rhode Island’s largest hospital that provides gender-affirming care to minors.

U.S. District Judge Mary McElroy’s Wednesday ruling is the latest setback for the U.S. Department of Justice, where at least seven other federal courts have agreed to quash or limit the expansive civil subpoenas sent to more than 20 doctors and hospitals last summer.

McElroy’s decision also echoed similar concerns raised by judges surrounding the expansive scope of the subpoenas, describing the Justice Department as having “immense prosecutorial authority and discretion” but no longer trustworthy it will enforce its power fairly and honestly.

“DOJ has proven unworthy of this trust at every point in this case,” McElroy wrote.

A Justice Department spokesperson said Thursday that it would appeal and continue with its investigations.

“The Rhode Island court’s attack on the professionalism and integrity of DOJ attorneys is outrageous and unjustified,” the department said.

According to the subpoenas, the Justice Department had demanded Rhode Island Hospital hand over the birth dates, Social Security numbers and addresses of every patient who received transgender care over the past five years. It also included instructions to provide all documents detailing adverse side effects in minor patients who received gender-related care, assessments that formed the basis for prescribing puberty blockers or hormone therapy, as well as patient intake forms and guardian authorization.

The Justice Department has repeatedly argued that the information sought in the subpoenas is needed to investigate possible fraud or unlawful off-label promotion of drugs. Most recently during a hearing in Rhode Island, the DOJ said that the investigation was taking place in the Northern District of Texas, where the court’s chief judge ordered Rhode Island Hospital to comply with the subpoena before McElroy’s decision voided the subpoena.

Assistant U.S. Atty. Brantley Mayers told McElroy during the hearing that the Justice Department is investigating potential “misbranding” of drugs approved by the U.S. Food and Drug Administration, such as puberty blockers for young people. While off-label prescribing is legal, Mayers said that the DOJ is concerned that pharmaceutical companies are providing “financial incentives” to Rhode Island doctors to prescribe the drugs.

The subpoenas were crucial in getting the names of children and their families so the Justice Department could interview them.

McElroy rejected that argument.

“The administration has publicly characterized gender-affirming care for minors as abuse, directed the DOJ to bring its practice to an end, and celebrated when hospitals curtailed such programs as a result of this subpoena campaign,” McElroy wrote.

The Rhode Island decision is the latest development in the fight over transgender youth health records. Earlier this week, 11 families filed a class-action lawsuit seeking to block the Justice Department from obtaining the documents. The lawsuit, filed in Maryland’s federal court, is backed by families with transgender children who have received care from hospitals across the U.S.

And separately, a New York hospital announced that it received a grand jury subpoena from federal prosecutors in Texas seeking information about children who received gender-affirming care and the medical providers who administered it.

NYU Langone is the first hospital system to publicly acknowledge receiving a subpoena for such records as part of a federal criminal investigation. But the institution said in its statement Tuesday it was one of several that received a subpoena out of the Northern District of Texas on May 7. It said it was deciding on how to respond.

“The government cannot use its subpoena power to intimidate families out of seeking lawful medical care. To trans and gender-diverse children and their families, we want you to know that you are valued, you are not alone,” Kevin Love Hubbard, an attorney with the Lawyers’ Committee of Rhode Island, who represented the plaintiffs in the case, said in a statement.

Gender-affirming care includes a range of medical and mental health services to support a person’s gender identity, including when it’s different from the sex they were assigned at birth. It may include counseling, medications that block puberty, hormone therapy to produce physical changes or surgeries to transform chests and genitals, although those are rare for minors.

Most major medical groups say access to the treatment is important for those with gender dysphoria and see gender as existing along a spectrum.

At least 27 states have adopted laws restricting or banning the care for minors, while several others have adopted laws or policies protecting access to transgender healthcare.

April 17 (UPI) — A federal judge on Friday blocked a lawsuit against the state of Hawaii that the federal government filed to prevent it from suing oil companies.

The Department of Justice last year sued Hawaii to stop a suit against fossil fuel companies for the impact of climate change on the state, but Senior Judge Helen Gillmor of the U.S. District Court in Hawaii said they it has no standing, The Hill and The New York Times reported.

In the ruling, Gillmor said that an “abstract, theoretical future harm” is not a valid basis for a lawsuit because stating an intention to file suit — which the state’s governor declared on television that he planned to do — does not amount to “concrete harm” that would allow an entity to sue.

Gillmor blocked the lawsuit because the DOJ’s theory of harm would require predicting claims brought against unknown companies; predicting that the lawsuit would be successful; “guessing” that oil companies would react in specific way; and then hypothesizing that the reaction would somehow harm the United States’ commerce and future energy policy, she wrote in the 30-page decision.

The DOJ’s suit, which was filed by now-former Attorney General Pam Bondi, alleged that Hawaii’s action was a “burdensome and ideologically motivated” lawsuit that could cause “crippling damages” with the energy and climate policies the state allegedly is pursuing.

“We disagree with the Hawaii District Court’s ruling, which ignored Supreme Court precedent regarding the United States’ interest in the supremacy of federal law,” the DOJ’s principal deputy assistant attorney general Adam Gustafson said in a statement. “We are exploring all options.”
