The Missouri Republican’s argument centers on the Fourteenth Amendment phrase “subject to the jurisdiction.” The fight is really about who gets the final word when Congress, the president and the courts disagree over constitutional meaning.
Sen. Eric Schmitt explains how Congress can respond to the Supreme Court’s interpretation of the Constitution by arguing lawmakers can define the Fourteenth Amendment’s Citizenship Clause more narrowly than courts and agencies have treated it for decades. Schmitt criticizes the Supreme Court’s reading of the Constitution as too broad on birthright citizenship, and his proposed fix points to congressional action: legislation, oversight and legal briefs that press the Court to revisit who is subject to the jurisdiction of the United States.
The Missouri Republican’s position is not just a dispute over immigration policy. It is a test of how far Congress can go when it believes the Supreme Court has adopted what Schmitt calls a mistaken constitutional interpretation.
The dispute behind Schmitt’s argument
Schmitt’s recent legal push centers on birthright citizenship, one of the most contentious readings of the Fourteenth Amendment. The amendment says, in part, that 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 where they reside.
For generations, the dominant legal understanding has been that most children born on U.S. soil are citizens at birth, with narrow exceptions such as children of foreign diplomats. Schmitt and other conservatives argue that the phrase subject to the jurisdiction thereof has been stretched too far.
In official materials from his Senate office, Schmitt has argued that citizenship should be reserved for children whose parents have a permanent and lawful bond to the United States. He has said that broader birthright citizenship for children of tourists and people in the country unlawfully betrays the text and original intent of the Fourteenth Amendment.
That argument also appeared in an amicus brief Schmitt and Rep. Chip Roy filed with the Supreme Court in support of President Donald Trump’s birthright citizenship executive order. Schmitt’s office described the brief as a defense of the original meaning of the Citizenship Clause.
How Congress could try to act
Schmitt’s core claim is that Congress is not powerless when it disagrees with the Supreme Court’s constitutional reading. The most direct route would be legislation stating how Congress understands the Citizenship Clause and who qualifies as subject to the jurisdiction of the United States.
Supporters of that approach would likely point to Section 5 of the Fourteenth Amendment, which gives Congress power to enforce the amendment through appropriate legislation. In their view, Congress can clarify the amendment’s scope and stop executive agencies from treating every birth on U.S. soil as automatically creating citizenship.
There are other tools short of a new law. Congressional committees can hold hearings, demand records from agencies, attach conditions to funding and file amicus briefs urging the justices to rethink past assumptions. Schmitt’s own record shows that legal briefs are part of the strategy, not an afterthought.
But the strongest version of his proposal would still need votes. A bill narrowing birthright citizenship would almost certainly face a Senate fight, possible filibuster pressure and immediate lawsuits. Even if Congress passed it and a president signed it, the Supreme Court would likely get the final say on whether Congress had enforced the Fourteenth Amendment or tried to rewrite it.
The constitutional obstacle is real
The major legal problem for Schmitt’s position is that Congress cannot simply override the Supreme Court’s interpretation of the Constitution the way it can revise an ordinary statute. If the Court says the Constitution protects a right, lawmakers cannot erase that right by declaring a different interpretation in federal law.
The Supreme Court has made that point in other contexts. In City of Boerne v. Flores, the Court held that Congress has enforcement power under the Fourteenth Amendment, but not power to redefine the amendment’s substantive meaning. That doctrine would be central to any challenge over a birthright citizenship statute.
Schmitt’s side would likely respond that the Court has never squarely decided the exact modern question involving children of people unlawfully present or temporarily visiting the country. The 1898 decision most often cited in this debate, United States v. Wong Kim Ark, involved a man born in San Francisco to Chinese parents who were lawfully domiciled in the United States.
That distinction is important to conservatives pushing a narrower reading. Critics say it is not enough. They argue that the plain text, historical practice and long-standing federal policy support birthright citizenship far more broadly than Schmitt allows.
Why Wong Kim Ark matters
Wong Kim Ark is the case both sides have to confront. The Supreme Court held that Wong Kim Ark, who was born in California and later denied reentry under the Chinese Exclusion Act, was a U.S. citizen by birth.
Supporters of broad birthright citizenship read the ruling as a sweeping confirmation of citizenship for nearly everyone born on American soil. They argue that the phrase subject to the jurisdiction generally means subject to U.S. law, not owing complete political allegiance in the way citizens do.
Schmitt and allies read the case more narrowly. In the amicus materials promoted by his office, they emphasize that Wong’s parents had established a permanent domicile and residence in the United States. Their position is that the decision does not resolve the status of children born to parents who are unlawfully present or only temporarily admitted.
That is why Schmitt’s criticism of the Supreme Court’s interpretation is about more than one case. It is an effort to separate what the Court actually held from what later officials, agencies and lower courts have assumed it means.
A fight over institutional power
The political appeal of Schmitt’s argument is clear. It tells conservative voters that Congress can do more than complain about the courts. It also fits a wider Republican push to reclaim authority from judges and administrative agencies after years of battles over immigration, regulation and presidential power.
Schmitt has used similar language in other legal-policy fights. His post-Chevron working group report, issued from his Senate office, framed Congress as responsible for reclaiming lawmaking authority after the Supreme Court curtailed judicial deference to federal agencies. The birthright citizenship debate is different, but the institutional theme is similar: Congress should not surrender constitutional meaning to other branches without a fight.
Democrats and many constitutional scholars see danger in that framing. If Congress can aggressively narrow constitutional guarantees whenever a majority dislikes a Supreme Court reading, rights could shift with election results. They also argue that birthright citizenship has provided a clear rule in a country built on immigration and equal citizenship after the Civil War.
There is a practical concern, too. A narrower rule could create uncertainty for hospitals, state vital records offices, passport agencies and families. Any new statutory line would have to answer hard questions about lawful permanent residents, visa holders, asylum seekers, temporary workers and people whose immigration status changes while a child is born.
What remains unresolved
Schmitt’s proposal depends on two separate victories. First, Congress would have to pass a meaningful restriction or clarification of birthright citizenship. Second, the Supreme Court would have to uphold it.
That second step is the bigger question. A conservative Court might be open to revisiting parts of the birthright citizenship debate, especially if presented with a carefully drafted statute or a direct challenge involving a presidential order. But the justices could also decide that more than a century of precedent and practice weighs against a major disruption.
For now, Schmitt’s argument is best understood as a pressure campaign as much as a legislative blueprint. It uses Congress’s tools to push a constitutional theory toward the Supreme Court and invites the justices to draw a line that current law has not clearly drawn.
The takeaway is simple: Schmitt says Congress can challenge what he sees as a flawed Supreme Court reading of the Constitution. Whether Congress can actually change the legal meaning of birthright citizenship is the fight that would come next.
