Here’s what happened.
President Donald Trump’s battle to tighten America’s birthright citizenship rules has hit another major legal roadblock, setting up a fresh confrontation over immigration, presidential authority and the meaning of the Fourteenth Amendment.
A Maryland federal judge temporarily halted Trump’s newest effort to limit automatic U.S. citizenship for some American-born children, handing the administration another legal setback only months after its previous strategy was rejected by the Supreme Court.
U.S. District Judge Deborah Boardman issued a preliminary injunction Wednesday against portions of Trump’s new birthright citizenship policy.
Boardman, who was appointed by former President Joe Biden, concluded that the administration’s latest effort is unlikely to survive its constitutional challenge.
“The 2026 Executive Order is almost certainly unconstitutional,” Boardman wrote, citing the Supreme Court’s earlier ruling in Trump v. Barbara.
The decision does not necessarily mark the end of Trump’s fight.
Instead, it opens another chapter in a legal battle that could once again place the politically explosive issue of birthright citizenship before the nation’s highest court.
Trump Takes Aim At Birth Tourism
At the center of the controversy is Trump’s attempt to crack down on what is commonly called “birth tourism.”
The term generally describes foreign nationals traveling to the United States on temporary visas for the purpose of giving birth on American soil.
Under the longstanding interpretation of the Fourteenth Amendment, most children born in the United States automatically become American citizens regardless of their parents’ immigration status, with limited exceptions.
Trump has challenged that interpretation as part of his broader effort to overhaul the nation’s immigration system.
After suffering a defeat at the Supreme Court over his original birthright citizenship order, Trump returned in August with a narrower strategy.
One executive action sought to identify additional circumstances in which children born in the United States would not qualify for automatic citizenship.
Another directed the Department of Homeland Security and State Department to take stronger action against birth tourism and the businesses or individuals that facilitate it.
The administration argues that American citizenship should not become a benefit deliberately obtained by exploiting temporary visa programs.
Supreme Court Decision Creates Major Obstacle
Trump’s biggest challenge is the Supreme Court’s June ruling in Trump v. Barbara.
The dispute centered on Trump’s January 2025 executive order seeking to deny automatic citizenship to certain children born in the United States when their parents were illegally or temporarily present in the country.
The Supreme Court rejected that position for the class involved in the case.
The Fourteenth Amendment states that all people born or naturalized in the United States and “subject to the jurisdiction thereof” are American citizens.
Those six words — “subject to the jurisdiction thereof” — have become critical to the modern debate.
Trump and supporters of a more restrictive interpretation argue that the Citizenship Clause should not necessarily be read as granting automatic citizenship in virtually every circumstance involving a child born on U.S. soil.
Opponents argue that the constitutional language, longstanding legal precedent and Supreme Court decisions leave presidents with little authority to impose such restrictions through executive action.
Boardman sided with the challengers at this stage of the case.
She determined that the Supreme Court had already established citizenship rights for children covered by the lawsuit, meaning the president could not eliminate those rights through another executive order.
White House Pushes Back
The Trump administration insists its new policy was deliberately written to comply with the Supreme Court’s decision.
Attorney General Todd Blanche defended the administration’s approach during an appearance on Fox News.
“We crafted the EO around, and in concurrence, and understanding what the Supreme Court said in their decision,” Blanche said.
The administration had anticipated additional legal challenges, he indicated, and appears prepared to continue defending the policy in court.
The White House was even more forceful in its response.
White House spokesperson Lauren Bis criticized the decision, arguing that it was another example of a Biden-appointed judge working to block President Trump’s policy agenda.
The administration argues that the updated executive order follows the Supreme Court’s legal reasoning instead of seeking a way around its ruling.
That disagreement could ultimately become the central question in the next phase of the case.
What Trump’s Executive Order Would Do
Trump’s August action goes beyond the citizenship debate itself by directing federal officials to take stronger measures against birth tourism.
The White House argues that temporary visas are being misused by foreign nationals who enter the country specifically to give birth.
Under the order, the Secretary of State and Secretary of Homeland Security were directed to take appropriate action against the practice.
Potential measures outlined by the administration include preventing entry into the United States, revoking visas or travel authorizations, removing individuals who violate immigration requirements and taking action against organizations involved in facilitating birth-tourism operations.
The State Department has also moved toward requiring additional documentation concerning citizenship or immigration status in certain passport applications involving children.
For Trump supporters, the larger concern is whether America’s citizenship system creates incentives for people to take advantage of the country’s immigration laws.
For opponents, the more fundamental issue is whether a president has the constitutional authority to change who qualifies as an American citizen.
The Fourteenth Amendment Is At The Center Of The Fight
The dispute ultimately comes down to competing interpretations of one of the most consequential provisions of the U.S. Constitution.
The Citizenship Clause of the Fourteenth Amendment was ratified in 1868.
It states:
“All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States.”
For generations, that language has generally been interpreted to provide citizenship to nearly everyone born on American soil.
There are recognized exceptions, including children born to certain foreign diplomats.
Trump has sought to test whether additional categories can legally fall outside the constitutional guarantee.
That argument has sparked an enormous debate over immigration, national sovereignty and the original meaning of the Fourteenth Amendment.
Another Court Fight Is Already Underway
The Maryland case is not the only challenge facing Trump’s new policy.
Another legal battle involving the administration’s executive actions is unfolding in New Hampshire.
That means different federal courts could weigh in as the administration attempts to implement its revised approach.
Depending on how those cases develop, the dispute could eventually climb through the appeals courts and potentially reach the Supreme Court again.
Trump has made immigration enforcement one of the defining priorities of his presidency, and there is little indication that his administration intends to abandon the birthright citizenship fight following Wednesday’s ruling.
The White House argues that the United States has a legitimate interest in preventing foreign visitors from deliberately exploiting temporary visas to obtain permanent advantages through their children.
Civil rights and immigrant advocacy organizations counter that citizenship guaranteed by the Constitution cannot be restricted by presidential order.
What Happens Next?
For now, the preliminary injunction prevents the administration from enforcing the challenged citizenship restrictions against the affected class while the lawsuit continues.
But a preliminary injunction is not necessarily the final word on the underlying legal dispute.
The administration can continue fighting the case and pursue appeals as it attempts to defend its revised policy.
That leaves Americans with another consequential constitutional showdown to watch.
The question is no longer simply whether Trump wants to change birthright citizenship.
It is whether the administration can find a legally permissible way to combat birth tourism and narrow citizenship eligibility after the Supreme Court has already placed significant limits on what the president can accomplish through executive action.
For the moment, Trump’s birthright citizenship agenda has encountered another roadblock.
But with multiple cases moving through federal courts and the administration promising to continue the fight, the battle over who automatically becomes an American citizen appears far from over.
