President Donald Trump vowed to continue fighting to end birthright citizenship after the U.S. Supreme Court dealt a significant blow to one of the defining immigration policies of his presidency. In a 6-3 decision issued Tuesday, the court struck down Trump’s executive order that sought to restrict automatic citizenship for children born in the United States to certain non-citizen parents, reaffirming longstanding constitutional protections under the 14th Amendment.

Although the ruling effectively ends Trump’s executive action, the president quickly shifted his focus to Congress, arguing that lawmakers could accomplish the same goal through legislation rather than a constitutional amendment.

Posting on Truth Social shortly after the decision, Trump said Congress should immediately begin work on legislation to end what he described as “expensive and unfair” birthright citizenship. He insisted lawmakers would have his “complete and total support” and argued that a constitutional amendment would not be necessary.

The Supreme Court case carried particular importance for Trump. Earlier this year, he became the first sitting U.S. president to attend oral arguments before the nation’s highest court, underscoring how central the issue has become to his immigration agenda.

Executive Order Challenged Constitutional Interpretation

Trump signed the executive order on his first day back in office. It sought to deny automatic U.S. citizenship to children born in the country unless at least one parent was either a U.S. citizen or a lawful permanent resident. Under the proposal, children born to undocumented immigrants, temporary workers, international students, or visitors would no longer automatically receive citizenship at birth.

Almost immediately after the order was issued, multiple federal courts blocked its implementation, setting the stage for the constitutional battle that ultimately reached the Supreme Court.

The majority of the justices concluded that the executive order conflicted with the Citizenship Clause of the 14th Amendment, which guarantees citizenship to “all persons born or naturalized in the United States, and subject to the jurisdiction thereof.”

Five justices explicitly found that the order violated the Constitution. Justice Brett Kavanaugh, one of Trump’s three Supreme Court appointees, agreed that the order was unlawful, although he based his reasoning on statutory grounds rather than a constitutional interpretation.

Constitutional Amendment Seen as Difficult Path

Legal experts note that because the court’s ruling rested largely on constitutional grounds, changing birthright citizenship would almost certainly require amending the Constitution rather than simply passing a federal law.

Such an amendment would face enormous political hurdles. Constitutional amendments require approval by two-thirds of both the House and Senate before being ratified by three-fourths of the states.

Sen. John Cornyn of Texas reminded the public of those requirements in a social media post, emphasizing the high threshold necessary to alter constitutional protections.

Even legislation short of a constitutional amendment would face significant obstacles in Congress. Senate Republicans currently hold 53 seats, well short of the 60 votes generally needed to overcome a filibuster on most legislation. Eliminating the legislative filibuster would lower that threshold, but Senate Republican leaders have repeatedly indicated they lack sufficient support within their own conference for such a move.

White House and Republican Allies Signal Continued Fight

Despite the legal setback, Trump administration officials and congressional Republicans signaled they have no intention of abandoning the issue.

White House Deputy Chief of Staff Stephen Miller sharply criticized the ruling, calling it one of the Supreme Court’s worst decisions and arguing that American citizenship should belong only to those with allegiance to the United States.

Several Republican lawmakers also pledged to pursue legislative and constitutional alternatives.

Sen. Eric Schmitt of Missouri announced plans to introduce a constitutional amendment modeled after Trump’s executive order. Schmitt argued that Congress has the authority to redefine citizenship requirements and framed mass migration as one of the nation’s most pressing challenges.

Another Setback Amid Mixed Supreme Court Record

The birthright citizenship ruling represents one of several recent legal defeats for Trump, even though the Supreme Court maintains a conservative majority that includes three justices he nominated during his first term.

In recent months, the court has ruled against several administration initiatives, including invalidating broad tariff actions, preventing the removal of a Federal Reserve governor, declining to limit certain voting rights protections, and allowing to stand a civil judgment involving writer E. Jean Carroll.

At the same time, Trump has secured major victories before the court. Earlier this week, the justices expanded presidential authority over independent federal agencies by overturning a decades-old precedent. The court has also ruled in favor of Trump in cases involving campaign finance and other executive powers.

Following Tuesday’s rulings, Trump emphasized those victories while acknowledging the loss on birthright citizenship, saying his administration would continue working with Congress to pursue changes to citizenship laws.

Democrats Celebrate Constitutional Victory

Democratic leaders across the political spectrum welcomed the Supreme Court’s decision, arguing that it reaffirmed one of the nation’s oldest constitutional guarantees.

Representatives Adriano Espaillat, Yvette Clarke, and Grace Meng, who chair the Congressional Hispanic, Black, and Asian Pacific American caucuses, issued a joint statement praising the ruling. They said the decision rejected what they characterized as an exclusionary vision of America and reaffirmed that birthright citizenship remains a defining constitutional protection.

New York Mayor Zohran Mamdani also applauded the decision, saying the ruling upheld a promise embedded in the Constitution for more than 150 years. He argued that citizenship should not depend on race, religion, ancestry, or the immigration status of one’s parents.

Representative Maxwell Frost of Florida likewise defended the ruling, stating that birthright citizenship has been settled constitutional law for generations and that attempts to narrow the guarantee were driven by political considerations rather than constitutional interpretation.

Americans Remain Divided on Birthright Citizenship

Public opinion on birthright citizenship remains mixed. A recent national survey found Americans nearly evenly divided over whether being born in the United States is an essential part of being “truly American.”

According to the poll, 54 percent of respondents said being born in the United States is important to American identity, while 45 percent disagreed. However, participants ranked other characteristics—including embracing American customs, traditions, and the principles of liberty and equality—as even more important indicators of what it means to be American.

The Supreme Court’s decision leaves the constitutional guarantee of birthright citizenship intact while ensuring that any future effort to change the policy would face extraordinarily high legal and political barriers. Although Trump has vowed to continue pursuing the issue through Congress, the current balance of power and the constitutional requirements for altering citizenship law make such changes unlikely in the near term.
