The legal battle over President Donald Trump’s move to end birthright citizenship is far from over despite the Republican administration’s major victory Friday limiting nationwide injunctions.

Immigrant advocates are vowing to fight to ensure birthright citizenship remains the law as the Republican president tries to do away with more than a century of precedent.

The high court’s ruling sends cases challenging the president’s birthright citizenship executive order back to the lower courts. But the ultimate fate of the president’s policy remains uncertain.

Here’s what to know about birthright citizenship, the Supreme Court’s ruling and what happens next.

What does birthright citizenship mean?

Birthright citizenship makes anyone born in the United States an American citizen, including children born to mothers in the country illegally.

The practice goes back to soon after the Civil War, when Congress ratified the Constitution’s 14th Amendment, in part to ensure that Black people, including former slaves, had citizenship.

“All persons born or naturalized in the United States and subject to the jurisdiction thereof, are citizens of the United States,” the amendment states.

Thirty years later, Wong Kim Ark, a man born in the U.S. to Chinese parents, was refused re-entry into the U.S. after traveling overseas. His suit led to the Supreme Court explicitly ruling that the amendment gives citizenship to anyone born in the U.S., no matter their parents’ legal status.

It has been seen since then as an intrinsic part of U.S. law, with only a handful of exceptions, such as for children born in the U.S. to foreign diplomats.

Trump has long said he wants to do away with birthright citizenship

Trump’s executive order, signed in January, seeks to deny citizenship to children who are born to people who are living in the U.S. illegally or temporarily. It’s part of the hardline immigration agenda of the president, who has called birthright citizenship a “magnet for illegal immigration.”

Trump and his supporters focus on one phrase in the amendment — “subject to the jurisdiction thereof” – saying it means the U.S. can deny citizenship to babies born to women in the country illegally.

A series of federal judges have said that’s not true, and issued nationwide injunctions stopping his order from taking effect.

“I’ve been on the bench for over four decades. I can’t remember another case where the question presented was as clear as this one is. This is a blatantly unconstitutional order,” U.S. District Judge John Coughenour said at a hearing earlier this year in his Seattle courtroom.

In Greenbelt, Maryland, a Washington suburb, U.S. District Judge Deborah Boardman wrote that “the Supreme Court has resoundingly rejected and no court in the country has ever endorsed” Trump’s interpretation of birthright citizenship.

Is Trump’s order constitutional? The justices didn’t say

The high court’s ruling was a major victory for the Trump administration in that it limited an individual judge’s authority in granting nationwide injunctions. The administration hailed the ruling as a monumental check on the powers of individual district court judges, whom Trump supporters have argued want to usurp the president’s authority with rulings blocking his priorities around immigration and other matters.

But the Supreme Court did not address the merits of Trump’s bid to enforce his birthright citizenship executive order.

“The Trump administration made a strategic decision, which I think quite clearly paid off, that they were going to challenge not the judges’ decisions on the merits, but on the scope of relief,” said Jessica Levinson, a Loyola Law School professor.

Attorney General Pam Bondi told reporters at the White House that the administration is “very confident” that the high court will ultimately side with the administration on the merits of the case.

Questions and uncertainty swirl around next steps

The justices kicked the cases challenging the birthright citizenship policy back down to the lower courts, where judges will have to decide how to tailor their orders to comply with the new ruling. The executive order remains blocked for at least 30 days, giving lower courts and the parties time to sort out the next steps.

The Supreme Court’s ruling leaves open the possibility that groups challenging the policy could still get nationwide relief through class-action lawsuits and seek certification as a nationwide class. Within hours after the ruling, two class-action suits had been filed in Maryland and New Hampshire seeking to block Trump’s order.

But obtaining nationwide relief through a class action is difficult as courts have put up hurdles to doing so over the years, said Suzette Malveaux, a Washington and Lee University law school professor.

“It’s not the case that a class action is a sort of easy, breezy way of getting around this problem of not having nationwide relief,” said Malveaux, who had urged the high court not to eliminate the nationwide injunctions.

The Supreme Court on Monday rejected an appeal from Minnesota asking to revive the state’s ban on gun-carry permits for young adults.

The justices also left in place a ban on guns at the University of Michigan, declining to hear an appeal from a man who argued he has a right to be armed on campus. No justice noted a dissent in either case.

Taken together, the actions reflect the high court’s apparent lack of appetite for cases that further explore the constitutional right to “keep and bear arms.”

The court has repeatedly turned away gun cases since its 2022 ruling that expanded gun rights and a clarifying 2024 decision that upheld a federal gun control law that is intended to protect victims of domestic violence.

The decision not to hear the Minnesota case was somewhat surprising because both sides sought the Supreme Court’s review and courts around the country have come to different conclusions about whether states can limit the gun rights of people aged 18 to 20 without violating the Constitution.

The federal appeals court in St. Louis ruled that the Minnesota ban conflicted with the Second Amendment, which the court noted sets no age limit and generally protects ordinary, law-abiding young adults.

In January, the federal appeals court in New Orleans struck down a federal law requiring young adults to be 21 to buy handguns.

In February, a federal judge declined to block Hawaii’s ban on gun possession for people under 21.

President Donald Trump said Thursday he is in “no rush” to reach any trade deals because he views tariffs as making the United States wealthy. But he suggested while meeting with Italian Premier Giorgia Meloni that it would be easy to find an agreement with the European Union and others.

Trump played down the likelihood of an accelerated timeline to wrap up deals, saying other countries “want to make deals more than I do.”

“We’re in no rush,” said Trump, hinting he has leverage because other countries want access to U.S. consumers.

Even though Trump has a warm relationship with Meloni, she was unable in their meeting to change his mind on tariffs.

“No, tariffs are making us rich. We were losing a lot of money under Biden,” Trump said of his predecessor, Democrat Joe Biden. “And now that whole tide is turned.”

Trump is convinced that his devotion to tariffs will yield unprecedented wealth for his country even as the stock market has dropped, interest on U.S. debt has risen and CEOs are warning of price increases and job losses in what increasingly looks like a threat to the existing structure of the world economy.

A bond market panic was enough for Trump to partially pull back on his tariffs, causing him to pause his 20% import taxes on the EU for 90 days and charge a baseline 10% instead. Meloni’s visit showed the challenge faced even by leaders who enjoy a rapport with Trump.

After they met, Trump told reporters that trade talks were easier than other business negotiations such as mergers. He said he had spoken with Chinese officials about tariffs “a lot” and the amount of his import taxes could be influenced by China approving a sale of the social media site TikTok. He also seemed to contradict his previous statement Thursday morning about being in no rush to make trade deals “over the next three or four weeks.”

Even then, Trump showed no interest in fully severing his tariffs. “Tariff negotiations are actually simpler than everyone has said,” Trump said. “A number of people are going to pay that number or they’re going to decide to go elsewhere if there is such a place. There really is no elsewhere.”

Meloni had, in a sense, been “knighted” to represent the EU at a critical juncture in the fast-evolving trade war that has stoked recession fears. The U.S. administration has belittled its European counterparts for not doing enough on national security while threatening their economies with tariffs, sparking deep uncertainty about the future of the trans-Atlantic alliance.

She sought to portray the U.S. and Europe as natural allies in Western civilization and said it was important to “try to sit down and find solution” to tensions over trade and national security.

The EU is defending what it calls “the most important commercial relationship in the world,’’ with annual trade with the U.S. totaling 1.6 trillion euros ($1.8 trillion). It was unclear, based on Meloni’s public interactions with Trump, whether the premier has a clear understanding of what Trump wants as part of an agreement.

His administration has said its tariffs would enable trade negotiations that would box out China, the world’s dominant manufacturer. But Trump maintains that rivals and allies alike have taken advantage of the U.S. on trade, a position that has frustrated long-standing partners and raised concerns about whether Trump is a trustworthy dealmaker.

Trump tried to push back against claims that his tariffs are harming the economy, saying that gasoline and egg prices are already dropping. The president blamed the Federal Reserve for interest rates rising on U.S. debt. Rates largely increased because investors were worried about Trump’s tariff plans and they became less willing to buy Treasury notes, while the central bank has held steady on its own benchmark rates because of economic uncertainty.

Louisiana Attorney General Liz Murrill is pushing forward with her efforts to force Orleans Parish Sheriff Susan Hutson to drop a longtime policy that generally prohibits deputies from directly engaging in federal immigration enforcement within the city’s jail.

In legal filings, Murrill claims that the policy — which the state characterizes as a so-called “sanctuary city” policy — is in direct conflict with a newly passed state law that requires state and local law enforcement agencies to cooperate with federal immigration agencies.

“The consent decree now sits fundamentally at odds with state law as applicable to immigration detainers,” Murrill said in court documents filed Friday.

A federal court will now determine whether to allow the state of Louisiana to join a 2011 federal suit that resulted in the policy and whether to throw out the policy altogether. A hearing has been set for April 30.

The state’s campaign against “sanctuary” policies comes as President Donald Trump is pushing local law enforcement agencies to join the federal government in his promised immigration crackdown. Since his inauguration, Trump has ordered the U.S. Department of Homeland Security to push for more partnerships between local law enforcement units and federal immigration agencies. A few have already signed up. Louisiana Gov. Jeff Landry, a longtime immigration hardliner and Trump ally, has worked with Republican lawmakers in the state to enact laws that encourage those collaborations.

As attorney general, Landry criticized a policy adopted by the New Orleans Police Department, under a long-running federal consent decree that blocks officers from enforcing immigration laws.

Neither Murrill’s office nor representatives for U.S. Immigration and Customs Enforcement responded to requests for comment.

In court filings, Murrill said Hutson “does not oppose the (state’s) intervention” in the case.” But a spokesperson for Hutson said that’s not exactly true. “It’s more accurate that we take no position regarding the state intervention,” a Sheriff’s Office spokesperson said in an emailed statement on Wednesday.

While she has not taken a position for or against increased collaboration with ICE, in an interview with Fox 8 in December, Hutson noted that the jail’s resources were far too stretched to take on immigration enforcement.

The sheriff’s policy stems from a 2013 federal court settlement in a civil rights case involving two New Orleans construction workers picked up on minor charges in 2009 and 2010. Mario Cacho and Antonio Ocampo sued after they were allegedly illegally held in the city’s jail past the completion of their sentences. The two were held at the request of U.S. Immigration and Customs Enforcement. The agency issues such “detainer” requests to local law enforcement agencies, asking them to hold onto arrestees who are suspected of immigration violations. Local agencies are only supposed to honor the hold requests for 48 hours, after which they should let detainees free. But in 2009 and 2010, then-Sheriff Marlin Gusman detained Cacho and Ocampo for months, according to legal filings in their case against the office.

Ocampo and Cacho settled the case with the Sheriff’s Office in 2013, and Gusman agreed to adopt a new policy on immigration investigations. The resulting policy blocks the agency from investigating immigration violations and from detaining immigrants for ICE without a court order, except in certain cases where they are facing charges for a small number of serious violent crimes.

Hungary will start the process to withdraw from the International Criminal Court, an official said Thursday, just as Israeli Prime Minister Benjamin Netanyahu arrived to red carpet treatment in the country’s capital despite an arrest warrant from the world’s only permanent global tribunal for war crimes and genocide.

Prime Minister Viktor Orbán gave the Israeli leader a welcome with full military honors in Budapest’s Castle District. The two close allies stood side by side as a military band played and an elaborate procession of soldiers on horseback and carrying swords and bayoneted rifles marched by.

As the ceremony unfolded, Orbán’s chief of staff, Gergely Gulyás, released a brief statement saying that “the government will initiate the withdrawal procedure” for leaving the court, which could take a year or more to complete. Netanyahu’s visit to Hungary, which is scheduled to last until Sunday, was only his second foreign trip since the ICC issued the warrant against him in November.

The ICC, based in The Hague, Netherlands, said when issuing its warrant that there was reason to believe Netanyahu and former Israeli Defense Minister Yoav Gallant had committed crimes against humanity in connection with the war in Gaza.

The war began when Hamas-led militants attacked southern Israel on Oct. 7, 2023, killing around 1,200 people, mostly civilians, and taking 251 hostages, most of whom have since been released in ceasefire agreements and other deals. Israel rescued eight living hostages and has recovered dozens of bodies.

Israel’s offensive has killed more than 50,000 Palestinians, according to Gaza’s Health Ministry, which doesn’t say whether those killed are civilians or combatants. Israel says it has killed around 20,000 militants, without providing evidence. Israeli military’s response resumed last month, shattering a ceasefire.

After the ICC issued the warrant, Orbán invited Netanyahu to Budapest, and accused the court of “interfering in an ongoing conflict for political purposes.” That invitation was in open defiance of the court’s ruling and contradicted Hungary’s obligations as a signatory to arrest any suspects facing a warrant if they set foot on their soil.

All countries in the 27-member European Union, including Hungary, are signatories, but the court relies on member countries to enforce its rulings. Hungary joined the court in 2001 during Orbán’s first term as prime minister.
