Anthony Romero, the man who made Trump back down on citizenship

Introduction: a historic constitutional victory driven by the ACLU

A presidential order finally rejected by the highest court

On June 30, 2026, the Supreme Court of the United States ruled that Donald Trump's attempt to abolish automatic birthright citizenship violated both the Constitution and federal law, according to a statement published by the American Civil Liberties Union. This ruling puts an end, at least temporarily, to one of the most controversial initiatives of the first day of the second presidential term.

Executive order 14160, signed on January 20, 2025, sought to strip automatic citizenship from children born on American soil to parents in the country illegally or on temporary status, a radical break from over a century of established constitutional practice.

The ACLU's executive director at the heart of the legal battle

Anthony D. Romero, executive director of the ACLU for more than two decades, called the ruling a "stunning loss" for Trump, noting that this signature order from his first day in office ultimately did not survive constitutional review by the nation's highest court.

This legal victory caps months of intense legal mobilization led by the organization, which coordinated multiple challenges across different federal jurisdictions since the initial signing of the contested order.

The path of a lawyer who became a civil rights icon

A career built on defending fundamental freedoms

Anthony Romero built his reputation on decades of commitment to civil liberties, taking the helm of the ACLU at a pivotal moment in recent American history and transforming the organization into a leading force in legal challenges against government policies deemed unconstitutional.

Under his leadership, the organization has ramped up legal challenges against controversial executive measures, consistently positioning itself as the first legal line of defense against what it views as violations of the fundamental constitutional rights of American citizens.

A patient and methodical legal strategy

The victory on birthright citizenship illustrates the long-term strategy favored by Romero and his organization: rather than rushing into hasty challenges, the ACLU built a solid legal case, relying on constitutional case law established over more than a century.

This methodical approach paid off before a Supreme Court nonetheless dominated by a conservative majority appointed largely by Republican presidents, showing that legal soundness can sometimes overcome presumed ideological divides.

The constitutional arguments that tipped the balance

The historic weight of the fourteenth amendment

The ACLU's central argument rested on a strict reading of the fourteenth amendment, ratified after the American Civil War, which guarantees citizenship to anyone born on American soil, regardless of their parents' immigration status.

Chief Justice John Roberts, who wrote the majority opinion, acknowledged the strength of this historical argument, drawing on more than a century of case law interpreting this clause consistently and without significant ambiguity.

A dissent that reveals internal fractures

Justices Clarence Thomas, Samuel Alito and Neil Gorsuch nonetheless dissented, revealing that even within the conservative majority, unanimity was far from guaranteed on this particularly sensitive constitutional question.

This internal fracture underscores the complexity of the case and the difficulty for the Trump administration in counting on automatic judicial support, even from justices it helped appoint itself.

The concrete impact on hundreds of thousands of families

A number that captures the human stakes

According to estimates from the Migration Policy Institute, roughly 255,000 children per year would have been directly affected by this order had it remained in force, losing their constitutional right to American citizenship from birth on national soil.

For these families, often already facing considerable administrative precarity, this Supreme Court ruling represents fundamental legal security that could have permanently slipped away without the judicial intervention of the ACLU and its partners.

Testimonies that humanize the legal debate

Beyond the abstract constitutional arguments, this legal battle involved very real families, confronted with the concrete anguish of seeing their children, born on American soil, stripped of a fundamental legal status guaranteed for over a century by the Constitution.

This human dimension, often overshadowed by technical legal debates, partly explains the extraordinary mobilization this case sparked across American civil society as a whole.

The White House's immediate pushback

Vance vows to keep up the legal fight

Vice President JD Vance acknowledged that the ruling "hangs by a thread," noting that only five of the six justices who rejected the order based their reasoning on strictly constitutional grounds, while Justice Brett Kavanaugh relied on separate statutory grounds.

This legal nuance, according to Vance, would leave the door open for future challenges should the Court's composition change in the years ahead, a prospect already worrying civil rights organizations.

The Justice Department shifts strategy

In response to this legal defeat, the Department of Justice reportedly received instructions to prioritize prosecutions related to "birth tourism," a marginal but politically sensitive practice that the administration now intends to target through other available legal means.

This strategic pivot illustrates the administration's determination to pursue its immigration goals through alternative avenues, despite the stinging defeat suffered on the main constitutional front.

Mixed reactions across the American political class

Democrats celebrate a constitutional victory

Senator Chuck Schumer hailed the ruling as a fundamental reaffirmation of the principle that "if you are born in America, you belong to America," summing up the Democratic camp's enthusiasm over this judicial setback dealt to the Republican administration.

Several civil rights organizations likewise praised the ruling as confirmation that federal courts remain capable of resisting executive attempts to bypass constitutional protections established over generations.

Republicans voice their disappointment

Speaker of the House Mike Johnson said he was "very disappointed" by the ruling, calling it a significant setback for the immigration reform efforts pursued by the Trump administration since its return to power.

This deep partisan divide once again illustrates the extreme polarization that now characterizes every major ruling handed down by the Supreme Court on matters touching immigration and American citizenship.

The ACLU faces its future legal battles

An organization energized by this victory

This victory marks a pivotal moment for the ACLU, strengthening its legitimacy and its capacity to mobilize for future legal battles ahead against other Trump administration initiatives deemed potentially unconstitutional.

Anthony Romero has already announced that his organization will continue to closely monitor any new attempt to circumvent this ruling through alternative legislative or administrative channels.

Similar cases still in the pipeline

Several other legal challenges, touching on issues related to immigration and constitutional rights, remain in preparation within the organization, which intends to maintain constant legal pressure on the current administration's full range of controversial immigration policies.

This ongoing dynamic of permanent legal contestation could define much of the American political and judicial landscape for the remainder of the current presidential term.

The historic precedent of the fourteenth amendment

A constitutional clause born of the Civil War

The fourteenth amendment, ratified in 1868 in the wake of the American Civil War, was initially intended to guarantee full citizenship to formerly enslaved people, before being interpreted more broadly to cover anyone born on American soil.

This deep constitutional history explains why the Supreme Court, despite considerable political pressure from the current administration, chose to preserve an interpretation established over more than a century rather than overturn it in the name of contemporary immigration concerns.

A founding ruling still invoked today

The landmark ruling in United States v. Wong Kim Ark, handed down in 1898, had already confirmed this expansive interpretation of birthright citizenship, a precedent the current Court explicitly invoked to justify its rejection of the order challenged by the Trump administration.

This historical reminder illustrates the depth of the legal roots underpinning the ACLU's winning argument before the nation's highest court.

The international stakes of this constitutional case

A signal sent to the rest of the democratic world

This Supreme Court ruling sends an important signal to Western democracies, demonstrating that American judicial institutions retain their ability to contain potential excesses of executive power, a reassuring message at a time when several authoritarian regimes are seeking to discredit Western democratic models.

China, Russia and Iran, regimes the West considers major structural threats, will no doubt watch closely this demonstration of American institutional resilience against attempts at excessive concentration of power.

A lesson in separation of powers for the West

This legal victory for the ACLU serves as a timely reminder that separation of powers remains an essential pillar of Western democracy, a principle that America's European allies are watching with particular interest given the current political context.

It is precisely this institutional capacity for self-correction that fundamentally distinguishes Western democracies from the authoritarian regimes the West must continue to contain on the world stage.

The next legal steps to watch

A battle far from truly over

Despite this resounding victory, several legal observers warn that the battle over birthright citizenship is far from truly over, with the Trump administration having clearly signaled its intent to pursue its efforts through other legal or legislative means.

Vice President Vance has already hinted at the possibility of new initiatives, suggesting this constitutional conflict will drag on in the months and years ahead.

The ACLU's continued vigilance on this case

Anthony Romero and his organization have vowed to remain extremely vigilant against any new attempt to bypass this ruling, mobilizing their considerable legal resources again if necessary to defend this fundamental constitutional principle.

This continued vigilance reflects the cyclical, never fully finished nature of America's great constitutional battles, where every legal victory must be defended and consolidated over time.

What this case reveals about the state of American democracy

A system of checks and balances that still works

This case demonstrates that the American system of separation of powers, despite the considerable strains it is currently under, retains its fundamental ability to uphold constitutional principles against the executive branch's most determined attempts to circumvent them.

This institutional resilience offers cautious grounds for optimism for anyone worried about authoritarian tendencies observed in some Western democracies confronted with determined populist leaders.

The irreplaceable role of organized civil society

The role played by the ACLU in this victory also underscores the irreplaceable importance of an organized, legally competent civil society, capable of bringing solid constitutional challenges against government policies deemed unconstitutional.

Without this structured citizen mobilization, this controversial order could likely have produced far more lasting effects before an effective legal challenge could be organized.

Persistent criticism of this judicial ruling

Conservative voices challenge the ruling's legitimacy

Some conservative commentators have criticized this ruling, arguing that it encroaches on the executive branch's constitutional prerogatives over immigration policy, an authority they consider historically belonging to the president and Congress rather than federal courts.

These criticisms, though a minority view in today's public debate, feed into a broader challenge to the very legitimacy of the Supreme Court to decide questions some consider more political than legal in nature.

The firm response from defenders of constitutional rights

Facing this criticism, the ACLU and its legal allies point out that constitutional interpretation remains precisely the core function of the Supreme Court, regardless of the political preferences of whichever administration happens to be in power at a given time.

This firm defense of the traditional judicial role illustrates the crucial importance of preserving judicial independence against political pressure, whatever the ideological leaning of the executive branch in office.

The lasting legacy of this constitutional battle

A precedent that will protect future generations

Beyond its immediate impact, this constitutional ruling will establish a lasting legal precedent, protecting future generations of children born on American soil against any similar attempt by future administrations to strip them of automatic citizenship.

This precedent significantly strengthens the legal security of millions of American families, regardless of their origin or immigration status, a constitutional gain now cemented by this landmark ruling.

A victory that outlasts the current political context

This victory for the ACLU and its director Anthony Romero extends far beyond the immediate political considerations of the Trump administration, standing within a long American tradition of fiercely defending fundamental constitutional principles against attempts to weaken them.

It is this lasting legacy, more than the political satisfaction of the moment, that truly constitutes the historic significance of this exceptional legal battle.

The role of lower courts before reaching the Supreme Court

A battle fought on several judicial fronts at once

Before reaching the Supreme Court, this case moved through several lower federal courts, where different judges issued sometimes contradictory rulings on the constitutionality of order 14160, creating considerable legal uncertainty for months for the families affected.

The ACLU had to coordinate a complex legal strategy across multiple jurisdictions simultaneously, a considerable logistical and legal effort that ultimately paid off before the nation's highest judicial body.

A collective victory beyond Anthony Romero alone

This final victory rests on the tireless work of dozens of lawyers and legal experts within the ACLU and its partner organizations, whose combined expertise helped build a legal case solid enough to convince a majority of conservative justices.

This collective dimension deserves recognition, even though Anthony Romero, as executive director, remains the most recognizable public face of this historic constitutional victory.

Conclusion: the lasting triumph of a constitutional principle

A victory that honors the spirit of the Constitution

This Supreme Court ruling, driven by the legal tenacity of Anthony Romero and the ACLU, honors the deep spirit of an American Constitution designed precisely to withstand the executive branch's periodic attempts to unilaterally redefine fundamental rights established over generations.

A fight that continues beyond this single victory

But this victory, significant as it is, marks only one stage in a broader constitutional fight that the ACLU and its allies will have to keep waging with the same determination against future administration attempts to redefine the contours of American citizenship.
