The Supreme Court heard arguments Tuesday in a high-stakes challenge to President Trump's executive order seeking to restrict birthright citizenship, with multiple justices appearing skeptical that the administration's position is constitutionally sound. The order, signed shortly after Trump took office, attempts to deny automatic citizenship to children born in the United States to parents who are in the country illegally or on temporary visas.

The 14th Amendment to the Constitution states that all persons born or naturalized in the United States and subject to its jurisdiction are citizens. For over a century, that language has been interpreted to grant citizenship to virtually all children born on U.S. soil regardless of their parents' immigration status. The administration argues the phrase "subject to the jurisdiction thereof" excludes children of undocumented immigrants and temporary visa holders.

Justices from both conservative and liberal wings of the court pressed government attorneys on the historical and legal foundations of the executive order, with several noting that a broad reading of the 14th Amendment has been the settled interpretation since an 1898 Supreme Court ruling. The government's position faced pointed questioning about whether a president can unilaterally redefine a constitutional provision through executive action alone.

Advocacy groups and several states that challenged the order warn that hundreds of thousands of people could lose citizenship status if the court sides with the administration. Lower courts had uniformly blocked the order from taking effect, and the current case before the justices partly concerns the scope of those nationwide injunctions, in addition to the underlying constitutional question.

A decision is expected by the end of June. Legal analysts across the spectrum noted that while the questioning suggested a difficult path for the administration on the merits, the court could issue a narrower ruling focused on the injunctions without fully resolving the constitutional question.
