The Supreme Court has delivered a significant ruling, striking down Executive Order 14160, President Donald Trump's attempt to deny automatic citizenship to children born on U.S. soil to parents who are not citizens or permanent residents. The 6-3 decision, announced recently, leaves the President's unilateral push to alter birthright citizenship in abeyance, although a concurring opinion from one of his own nominees has outlined a potential legislative route for Congress to address the issue.
"Congress could — consistent with the Fourteenth Amendment—amend §1401(a) or otherwise enact new legislation establishing exceptions to birthright citizenship for children born to foreign citizens unlawfully or temporarily in the country." — Justice Brett Kavanaugh, Supreme Court
Justice Brett Kavanaugh joined the majority in blocking President Trump's executive order, but his separate concurring opinion provided a detailed framework for lawmakers. Rather than viewing the dispute as a constitutional matter, Justice Kavanaugh argued that the case primarily hinged on existing statutory law. He traced the current rule to 1940, when Congress first codified the 14th Amendment’s citizenship guarantee into federal statute, later integrating it into the Immigration and Nationality Act of 1952. Kavanaugh emphasized that this legislative action occurred after the Supreme Court's 1898 decision in *United States v. Wong Kim Ark*, which affirmed automatic citizenship for most individuals born in the U.S. This sequence, he argued, effectively embedded the judicial interpretation into law, meaning the President lacked the power to unilaterally rewrite a statute via executive order.
However, Justice Kavanaugh's opinion also signaled a clear path for the legislative branch, suggesting that Congress retains the authority to establish new limits on birthright citizenship. He wrote, “Congress could — consistent with the Fourteenth Amendment—amend §1401(a) or otherwise enact new legislation establishing exceptions to birthright citizenship for children born to foreign citizens unlawfully or temporarily in the country.” He further noted that contemporary conditions, such as mass illegal immigration and the ease of international travel, differ significantly from the Reconstruction era when the 14th Amendment was ratified. These modern realities, he contended, could justify new categories of exceptions, similar to the long-standing exclusions for children of diplomats or occupying enemy soldiers.
While the full court did not adopt Kavanaugh’s underlying theory, Republican leaders quickly pivoted toward legislative action. House Speaker Mike Johnson addressed reporters following the decision, stating his belief that the citizenship guarantee has been "thwarted and overused and abused." He indicated support for a constitutional amendment, saying, “I’m sure that the conclusion from this decision is you have to amend the Constitution to fix that.”
Senator Rand Paul also seized on the ruling to renew his call for a constitutional amendment, which he had previously introduced. “I introduced a constitutional amendment months ago, actually, to fix birthright citizenship,” Paul posted on X. “After the Supreme Court decision, that amendment matters more than ever. I’m asking my colleagues to take it seriously and help me get this passed.” Similarly, Senator Mike Lee used the platform to advocate for a constitutional amendment, linking it to border enforcement and legal accountability. “The long fight for a constitutional amendment begins now,” Lee wrote. “We must explicitly exclude foreign nationals who break our laws, violate our borders, or exploit loopholes to make their families American.”
President Trump, however, expressed a different view, contending that a constitutional amendment is not necessary. On Truth Social, President Trump posted, “No long and unwieldy Constitutional Amendment is necessary! Congress should start TODAY to work on ending expensive and unfair to our Country, Birthright Citizenship. They will have my Complete and Total Support!”
Several bills addressing birthright citizenship are already before Congress, including Senator Tom Cotton’s Constitutional Citizenship Clarification Act and proposals from Senators John Cornyn and Rick Scott targeting "birth tourism." The Justice Department, in response to the ruling, has also indicated a shift in strategy, planning to combat birth tourism through visa fraud prosecutions rather than continuing attempts to enforce the now-blocked executive order.
Legal scholars, however, caution that Justice Kavanaugh's suggested legislative path is not without significant hurdles. A separate 5-4 majority in the Supreme Court has previously held that the citizenship clause itself constitutionally protects birthright citizenship, meaning any new legislation would almost certainly face immediate court challenges. Notre Dame law professor Haley Proctor noted the uncertainty even among dissenting justices regarding the ruling's permanence. Proctor told Fox News Digital, “Justice Thomas says in the final paragraph of his dissent that he’s not confident that the decision is going to stand the test of time, so it could well be that the court would revisit it if Congress were to take the steps that Justice Kavanaugh describes.” She added, “This is an important decision. I don’t think the court’s going to revisit it lightly, and the only sure way to get a new answer here would be to amend the Constitution.”
Justice Kavanaugh has previously offered similar guidance in cases where President Trump's actions were challenged. In a recent tariff dispute, the Court ruled President Trump lacked authority under a federal emergency law, but Kavanaugh framed the decision as a matter of using the wrong legal tool rather not an unlawful objective, pointing toward alternative trade laws. President Trump subsequently praised Kavanaugh as his “new hero” following that earlier ruling.
