Trump’s birthright citizenship ban may fail — but the administration already got too far

Trump’s birthright citizenship ban may fail — but the administration already got too far

Tech-news , ,

On Wednesday morning, the Supreme Court heard arguments in Trump v. Barbara, a case challenging President Donald Trump’s 2025 executive order banning birthright citizenship. Justices seemed skeptical of the administration’s argument, but by taking up birthright citizenship at all, they showed how much ground nativists have gained since Trump’s first term. The 14th Amendment is quite clear: “all persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.” Trump seeks to overturn this and create a new, effectively stateless American underclass, and he’s gotten alarmingly far.

Hours after being sworn back into office for his second term, Trump issued an executive order titled “Protecting the Meaning and Value of American Citizenship.” Under the order, children born to undocumented mothers — or to women in the country on non-immigrant visas — would no longer be citizens upon birth, unless the children’s fathers were citizens or permanent residents. The order’s provisions would take effect 30 days after it was issued. It was immediately challenged in court and several federal injunctions prevented its implementation, meaning birthright citizenship remains the law of the land for now.

Trump’s efforts hinge on the meaning of a specific clause: “subject to the jurisdiction thereof.” The administration contends that noncitizens and those who don’t have permanent residency are not subject to the jurisdiction of the United States, since they’re actually loyal to a foreign power. This interpretation would reverse not only centuries of US law but also precedent set by English common law, leaving hundreds of thousands of children without status or stateless upon birth. Karen Tumlin, the director of the Justice Action Center, called the case a “canary in the coalmine for our democracy”: if Trump can end birthright citizenship with the stroke of a pen, then no constitutional protection is safe.

All but the most conservative justices seemed unconvinced. Their questions largely focused on two landmark decisions. One was Dred Scott v. Sandford, the 1857 case in which the court decided that enslaved people were not citizens — which the 14th Amendment was ratified partly to overturn. The other was United States v. Wong Kim Ark, an 1898 case in which the court ruled that, despite the Chinese Exclusion Act, the American-born children of Chinese nationals were indeed US citizens.

After Justice Clarence Thomas asked Sauer how the citizenship clause responds to Dred Scott, Sauer acknowledged that the 1857 decision “imposed one of the worst injustices in the history of this court.” But he argued that Congress specifically ratified the 14th Amendment to grant citizenship to “newly freed slaves and their children” who, according to Sauer, had “a relationship of domicile” to the United States and no “relationship to any foreign power.”

Nineteenth-century legislators, Sauer argued, couldn’t have foreseen the problem of birth tourism. “There are 500 — 500 — birth tourism companies in the People’s Republic of China whose business is to bring people here to give birth and return to that nation,” Sauer said. The current interpretation of birthright citizenship “could not possibly have been approved by the 19th century framers of this amendment,” he said. “We’re in a new world,” he continued, “where 8 billion people are one plane ride away from having a child who’s a US citizen.”

Justice Neil Gorsuch, who was questioning Sauer, appeared unswayed. “It’s a new world,” he agreed, but “it’s the same Constitution.”

“It’s a new world,” Gorsuch said, but “it’s the same Constitution”

Chief Justice John Roberts called Sauer’s examples of existing exceptions — including children of ambassadors or enemies during a hostile invasion — “very quirky” and not necessarily comparable to“a whole class of illegal aliens who are here in the country.” Justice Elena Kagan noted that most of Sauer’s brief focused on people who are temporarily in the country on visas — but Trump’s executive order was clearly intended to restrict immigration, and the president has said so himself.

In 2019, Trump called birthright citizenship a “magnet for illegal immigration.” Last year, presidential adviser Stephen Miller said the US-born children of immigrants are just as much of a problem as the immigrants themselves. “With a lot of these immigrant groups, not only is the first generation unsuccessful,” Miller said in a Fox News interview, citing the Somali-American community, which the administration would soon target in Minneapolis, as an example. “You see persistent issues in every subsequent generation. So you see consistent high rates of welfare use, consistent high rates of criminal activity, consistent failures to assimilate.”

The administration has sought to restrict legal immigration in all its forms: it implemented a steep fee for H-1B work visas, has signaled it may end a work program for international students, and enacted a travel ban on several countries that is even affecting World Cup players. The operation is barefacedly racist. The president famously complained about “all these people from shithole countries” who migrate and expressed his desire to have “more people from Norway.” Last year, he cut the refugee resettlement cap to just 7,500 and prioritized the resettlement of white South Africans. The Department of Homeland Security has linked the “homeland” to a decidedly white vision of Manifest Destiny that, like debates about birthright citizenship, harkens back to the nineteenth century.

Experts are broadly in agreement that most justices weren’t convinced by the administration’s argument, but it’s not clear exactly how the court will rule.

If the court did hand Trump an unexpected victory, a series of grim questions would immediately come into play — starting with when the change kicks in. The order was supposed to be implemented on February 19, 2025, thirty days after Trump signed the order, and would have gone into effect if not for a number of federal injunctions. “If the court sides with Trump, it will have to decide on a date on which to begin applying the president’s interpretation of the 14th amendment,” César Cuauhtémoc García Hernández, a professor of civil rights and civil liberties at the Ohio State University College of Law, told The Verge. “Anyone born on or after that date and described in Trump’s order would be treated as a migrant rather than a U.S. citizen.”

Sauer asked the court to apply Trump’s executive order “proactively” and not retroactively, and backdating the change to 2025 would pose a number of problems, calling the citizenship of millions of children into question.

The Trump administration is trying to narrow who counts as an American while simultaneously pushing for policies that prevent noncitizens from participating in public life. The administration has tried to prohibit states from offering in-state tuition to undocumented immigrants who live there, revoked accreditation for training centers that work with noncitizen truckers, and has broadly sought to turn America into a “papers, please” country.

Trump was in the audience during Wednesday’s arguments, making him the first sitting president to attend oral arguments before the Supreme Court. His presence may have intended to intimidate skeptical justices into taking his side. Norman Wong, a direct descendant of Wong Kim Ark, was also outside the courthouse, according to the New York Times. Wong and his family embody the stakes of this case, and he had a message for the justices: “They will be shamed for history if they get this wrong.”

Miles Wang, an OpenAI researcher whose work includes using AI to accelerate scientific and biological discovery, is leaving the ChatGPT maker to launch a new startup focused on developing AI models for drug discovery, according to four people with knowledge of his plans. Several other OpenAI researchers are expected to join the new company.  

Wang is in talks to raise about $200 million at a $2 billion valuation, two of the people said. Lightspeed is in discussions to lead the funding round, according to sources. Talks are ongoing, the deal may not be final and details could change.

Wang disputed the story’s funding figures and description of the company but did not specify the correct numbers or details. Lightspeed didn’t respond to a request for comment.

The funding discussions point to investor interest in applying AI to make breakthroughs in life sciences. Chai Discovery, a two-year-old startup developing AI models that can predict molecular interactions to identify new drugs, announced on Tuesday that it raised $400 million at a $3.8 billion valuation. (Co-founder Josh Meier also passed through OpenAI as a researcher.) Meanwhile, Google DeepMind spinout Isomorphic Labs, which also develops AI models for drug discovery, raised a $2.1 billion Series B in May.

Wang’s new startup may be working on AI models that will help find new uses for existing drugs and possibly those that previously failed in trials, a couple of sources told TechCrunch. Finding new uses for FDA-approved drugs can result in significantly faster time to revenue than developing new drugs from scratch, as these medicines have already been tested for safety.

Wang joined OpenAI in 2024 after dropping out from Harvard, where he was working on a bachelor’s degree in computer science. (In recent years, investors are once again comfortable betting on young founders who haven’t completed college.)

At OpenAI, he co-authored research papers, including evaluating how AI models can automate and accelerate scientific discovery.

Like it or not, data centers are now intrinsic to our modern lives, supporting not just the AI boom but healthcare, banking, government services, and other essential sectors. Reliable data center operation depends on effective cooling, which is already a major challenge as many methods require huge inputs of water or energy. To make matters worse, new research suggests that one of our cheapest, most efficient cooling strategies could stop working in a warmer world.

The findings, published Monday in the journal Scientific Reports, show that rising temperatures and humidity levels threaten the viability of direct air free cooling, an energy-efficient, waterless technique that pulls outside air in to cool data center servers. Over the past 45 years, weather conditions that limit direct air cooling have become significantly more common, particularly across the tropics and the southeastern United States, according to the study. As the global temperature continues to rise, this problem is only going to get worse.

“We found that periods of time when temperature and humidity exceed recommended operating thresholds for direct air free cooling are becoming more frequent and lasting longer in many regions,” lead author Christina Karamperidou, a professor of atmospheric sciences professor at the University of Hawaii at Mānoa, said in a statement. “This will reduce the availability of air free cooling for a growing number of data centers globally.”

Climate-driven cooling constraints

For direct air free cooling, the American Society of Heating, Refrigerating and Air-Conditioning Engineers recommends keeping the air entering a data center between 64 and 81 degrees Fahrenheit (18 and 27 degrees Celsius), with 10% to 70% relative humidity and a dew point below 59 degrees F (15 degrees C). Air that is hotter and more humid than this won’t cool the servers effectively and could corrode metal components.

To investigate how this cooling method will function in a warmer, wetter world, Karamperidou and her colleagues used a combination of high-resolution hourly weather observations, climate model simulations, and global records of data center locations. With this data, they evaluated how often environmental conditions exceeded recommended operating limits for direct air free cooling over the past 45 years and in future climate scenarios.

The researchers found that the prevalence of weather conditions that limit direct air free cooling has increased significantly in recent decades. Even regions that have only seen modest long-term increases in heat and humidity are experiencing longer daily exceedance events, and the share of data centers exposed to conditions that limit direct air free cooling availability for at least one quarter of the year is rising.

Interestingly, the findings suggest that the hottest, most humid days are intensifying faster than average days, indicating that environmental stress on direct air free cooling systems is become more and more concentrated in rare, highly consequential events.

“From an operational perspective, those worst-day conditions often drive contingency planning, system overrides, redundancy requirements, and reliability decisions,” Karamperidou said. “This suggests that infrastructure planning may need to account not only for average environmental conditions but also for how the most stressful days are changing over time.”

By 2050, the number of hours that exceed temperature and humidity limits for direct air free cooling is protected to increase under high greenhouse gas emissions scenarios, according to the researchers. In most regions globally, the average number of hours per day during which this cooling strategy is constrained increases by more than two hours per day, the findings show.

A troubling feedback loop

While this study focuses on how weather can influence data centers, it’s important to remember that data centers can influence local weather too. These facilities dissipate a lot of heat, and research has shown that they can actually create heat islands within a 6-mile radius of themselves.

Karamperidou and her colleagues did not account for this effect, so the direct air free cooling constraints they identified may be conservative, they write in their report. Still, they emphasize that their findings do not mean that this cooling strategy is necessarily infeasible in warm, humid regions. Rather, the study shows that the window of feasibility for direct air free cooling is narrowing due to climate change.

“Alternative strategies—including indirect evaporative cooling, liquid cooling, and hybrid architectures—can partially offset these constraints, albeit with distinct trade-offs in water use, system complexity, and operational design,” the researchers write.

Indeed, as one of the simplest, cheapest, and most efficient cooling strategies becomes increasingly unreliable, data center operators may be forced to turn to more energy- and water-intensive methods. This, in turn, could put added strain on electric grids and water resources that are themselves strained by climate change. Adapting data centers to a warming world without exacerbating the impacts of rising global temperatures will require innovative solutions.

AI boom but healthcare, banking, government services, and other essential sectors. Reliable data center operation depends on effective cooling, which is already a major challenge as many methods require huge inputs of water or energy. To make matters worse, new research suggests that one of our cheapest, most efficient cooling strategies could stop working in a warmer world.

The findings, published Monday in the journal Scientific Reports, show that rising temperatures and humidity levels threaten the viability of direct air free cooling, an energy-efficient, waterless technique that pulls outside air in to cool data center servers. Over the past 45 years, weather conditions that limit direct air cooling have become significantly more common, particularly across the tropics and the southeastern United States, according to the study. As the global temperature continues to rise, this problem is only going to get worse.

“We found that periods of time when temperature and humidity exceed recommended operating thresholds for direct air free cooling are becoming more frequent and lasting longer in many regions,” lead author Christina Karamperidou, a professor of atmospheric sciences professor at the University of Hawaii at Mānoa, said in a statement. “This will reduce the availability of air free cooling for a growing number of data centers globally.”

Climate-driven cooling constraints

For direct air free cooling, the American Society of Heating, Refrigerating and Air-Conditioning Engineers recommends keeping the air entering a data center between 64 and 81 degrees Fahrenheit (18 and 27 degrees Celsius), with 10% to 70% relative humidity and a dew point below 59 degrees F (15 degrees C). Air that is hotter and more humid than this won’t cool the servers effectively and could corrode metal components.

To investigate how this cooling method will function in a warmer, wetter world, Karamperidou and her colleagues used a combination of high-resolution hourly weather observations, climate model simulations, and global records of data center locations. With this data, they evaluated how often environmental conditions exceeded recommended operating limits for direct air free cooling over the past 45 years and in future climate scenarios.

The researchers found that the prevalence of weather conditions that limit direct air free cooling has increased significantly in recent decades. Even regions that have only seen modest long-term increases in heat and humidity are experiencing longer daily exceedance events, and the share of data centers exposed to conditions that limit direct air free cooling availability for at least one quarter of the year is rising.

Interestingly, the findings suggest that the hottest, most humid days are intensifying faster than average days, indicating that environmental stress on direct air free cooling systems is become more and more concentrated in rare, highly consequential events.

“From an operational perspective, those worst-day conditions often drive contingency planning, system overrides, redundancy requirements, and reliability decisions,” Karamperidou said. “This suggests that infrastructure planning may need to account not only for average environmental conditions but also for how the most stressful days are changing over time.”

By 2050, the number of hours that exceed temperature and humidity limits for direct air free cooling is protected to increase under high greenhouse gas emissions scenarios, according to the researchers. In most regions globally, the average number of hours per day during which this cooling strategy is constrained increases by more than two hours per day, the findings show.

A troubling feedback loop

While this study focuses on how weather can influence data centers, it’s important to remember that data centers can influence local weather too. These facilities dissipate a lot of heat, and research has shown that they can actually create heat islands within a 6-mile radius of themselves.

Karamperidou and her colleagues did not account for this effect, so the direct air free cooling constraints they identified may be conservative, they write in their report. Still, they emphasize that their findings do not mean that this cooling strategy is necessarily infeasible in warm, humid regions. Rather, the study shows that the window of feasibility for direct air free cooling is narrowing due to climate change.
