Homeland Security Secretary Markwayne Mullin told Fox News he is working with Health and Human Services on a policy that could bar pregnant women from entering the United States, drawing a comparison to restrictions on travelers carrying infectious diseases.
Mullin's remarks came one day after U.S. District Judge Deborah Boardman blocked President Trump's latest executive order targeting birthright citizenship, calling it "certainly unconstitutional." The ruling was the second federal rebuke of the administration's efforts to narrow who qualifies for citizenship at birth. The Supreme Court struck down a separate 2025 executive order on the same subject in June.
With the courts blocking the constitutional route, the administration appears to be searching for a regulatory side door. Mullin's Fox News appearance offered the clearest signal yet of what that workaround might look like, and it raised immediate questions about scope, enforceability, and legal authority.
During the broadcast, Mullin argued that existing public-health travel restrictions provide a template for barring pregnant women at the border. He pointed to rules that prevent travelers from entering the country if they come from regions with communicable-disease outbreaks.
"Maybe you shouldn't come into the country if you are late in your third term. We don't allow sick individuals to come here if they are coming from an area that could possibly, come in, that could spread a disease. So there is precedent for us to look into saying it's not safe for you to travel."
Mullin then pivoted to a personal anecdote to bolster his case.
"I know my grandson was just recently born and her OBGYN didn't want her flying late into her third trimester."
The comparison is worth examining on its own terms. Infectious-disease restrictions exist because a sick traveler can transmit illness to others, a direct public-health threat to the receiving population. A pregnant woman poses no such threat. Mullin's analogy conflates two categories that share almost nothing in common beyond the fact that both involve a physical condition and air travel. The policy question, whether foreign nationals travel to the U.S. specifically to give birth on American soil, is legitimate. The comparison he chose to frame it was not.
Mullin also did not explain how a travel restriction would apply to people who enter the country by land or sea. The proposal, as he described it, appeared tethered to air travel and an obstetrician's advice about flying, a framing that ignores the reality that the U.S. shares a nearly 2,000-mile land border with Mexico.
The Center for Immigration Studies, an organization that advocates for lower immigration levels, estimated in 2020 that between 20,000 and 26,000 birth-tourism cases occur in the United States each year. That same year, the country recorded 3.61 million total births. Birth tourism, by that estimate, accounts for less than 1 percent of all births on American soil.
None of that means the practice is acceptable. Foreign nationals who time their travel to secure U.S. citizenship for a child, and the downstream access to public benefits that comes with it, exploit a system that was never designed for that purpose. Trump has signed executive orders targeting both birthright citizenship and birth tourism, making clear the administration views the issue as a priority.
But a policy problem that involves fewer than 26,000 cases a year does not automatically justify a blanket restriction on pregnant women entering the country. The question is whether the administration can craft a targeted, enforceable measure, or whether it will reach for something broad enough to create new problems of its own.
White House deputy chief of staff Stephen Miller had already laid the groundwork for this policy direction after the Supreme Court's June ruling. In an appearance on Fox News with host Jesse Watters, Miller argued that birthright citizenship creates perverse incentives for foreign nationals to enter the country temporarily for the sole purpose of giving birth.
"But if you have birthright citizenship, it means if a person comes here nine months pregnant to go look around at some things, in a couple of weeks, that is the mother of a lifetime American citizen and a direct line into American cash and welfare for the rest of that child's life."
Miller went further, telling Watters that the administration would need to rethink who it allows into the country even on short-term visas.
"Well, what I'm saying, Jesse, is that you have to now think very carefully about who you let into your country, even on a temporary basis, because the possibility, as you said, for birth tourism, right, they do that. People come here just to have babies on American soil, and that baby gets to be a citizen for life."
Miller's argument is more disciplined than Mullin's. He identified a specific incentive structure, birthright citizenship combined with permissive visa policies, and argued the combination invites exploitation. That is a policy argument grounded in observable behavior. Mullin's version, by contrast, wandered into a medical analogy that undermined the seriousness of his own position.
The administration has faced repeated setbacks in court over its birthright citizenship efforts. Trump called on the Supreme Court to rehear the case after losing on a narrow 5-4 vote, and the White House has continued to pursue the issue through new executive orders even after the high court's ruling.
Judge Boardman's Wednesday ruling blocking the latest executive order cited the Supreme Court's June decision as controlling precedent. By calling the new order "certainly unconstitutional," she signaled that the judiciary views the administration's repeated attempts to limit birthright citizenship through executive action as foreclosed by the high court's ruling.
That legal reality is what makes Mullin's pivot to a travel-restriction framework significant. If the courts will not allow the administration to redefine who qualifies for citizenship at birth, the fallback is to prevent the births from happening on U.S. soil in the first place. The strategy shifts from rewriting the Fourteenth Amendment's reach to controlling who physically enters the country.
Earlier in the legal battle, a federal judge declined to immediately block one of Trump's birthright citizenship orders, giving the administration a brief window before the higher courts weighed in. That window has now closed.
Mullin offered no specifics on how the proposed HHS collaboration would work. He did not say whether the restriction would apply to all pregnant women or only those in the third trimester. He did not address whether it would cover land crossings, sea arrivals, or only air travel. He did not name a legal authority for the policy beyond the infectious-disease analogy.
Government interventions that touch pregnancy have a track record of producing unintended consequences when officials prioritize ideological goals over practical reality. California's experience with SB132, a law requiring prisons to house inmates according to their stated gender identity, offers a cautionary example from the other end of the political spectrum. At least one woman at the state's Central California Women's Facility became pregnant after being housed with a male-born transgender inmate transferred under the law. State officials responded not by reversing the housing policy but by distributing condoms and drugs to induce abortions.
The lesson cuts across party lines: policies that treat pregnancy as an abstraction, whether to score progressive points on gender ideology or to build a workaround for a lost court battle on citizenship, tend to collide with reality in ways their architects did not anticipate.
The administration's frustration with the courts is understandable. Birth tourism exploits a constitutional provision in ways the framers of the Fourteenth Amendment could not have foreseen. The Supreme Court's 5-4 decision left the White House with few options, and the executive orders Trump signed after that loss reflected a determination to keep pressing the issue.
But comparing pregnant women to disease carriers is not the way to build public support for a serious policy. It hands critics a sound bite that drowns out the legitimate concern underneath. And floating a restriction without explaining how it would be enforced, or whether it would survive its own day in court, suggests the proposal is more about signaling defiance than solving the problem.
Mullin's Fox News appearance left several basic questions unresolved. What legal authority would the administration invoke to bar pregnant women from entering the country? Would the restriction apply at ports of entry, consular visa interviews, or both? Would it cover all pregnant women or only those past a certain gestational threshold? And would it apply to U.S. citizens returning from abroad, or only to foreign nationals?
The administration has also not addressed whether such a policy would face immediate legal challenge on equal-protection or due-process grounds, a near certainty given the judiciary's posture on every prior birthright citizenship measure. Concerns about noncitizen access to civic institutions remain a live issue across multiple policy fronts, but each new executive action invites its own courtroom fight.
Until those questions get answers, Mullin's proposal remains what it sounded like on Fox News: an idea looking for a mechanism, wrapped in an analogy that did more harm than good.
Birth tourism is a real problem that deserves a serious fix. Comparing expectant mothers to disease vectors is not serious, it is the kind of careless framing that turns a winnable argument into an unnecessary fight.
