Kentucky Republican leaders are calling for a constitutional amendment to restrict birthright citizenship following the U.S. Supreme Court's decision upholding a broad conception of birthright citizenship, rejecting an executive order by President Donald Trump that sought to deny citizenship to children born to parents in the United States illegally or temporarily.

The high court's ruling marked a significant setback for the Trump administration's immigration agenda. The president's executive order had attempted to reinterpret the 14th Amendment to exclude children born to undocumented immigrants or those on temporary visas from automatic citizenship at birth.

Kentucky GOP officials have responded to the decision by renewing efforts to pass a federal constitutional amendment that would end birthright citizenship as currently guaranteed under the 14th Amendment's citizenship clause. Supporters of such amendments argue that restricting automatic citizenship would give Congress greater control over immigration policy and ensure that citizenship status aligns with legal immigration status.

The push for a constitutional amendment represents a more permanent solution than the executive order approach, as such amendments require approval from two-thirds of both the House and Senate, followed by ratification by three-fourths of state legislatures. The threshold is intentionally high, making constitutional amendments difficult to pass.

Birthright citizenship has been a cornerstone of U.S. immigration law since the passage of the 14th Amendment following the Civil War. The Supreme Court's 1898 decision in United States v. Wong Kim Ark established that children born to non-citizen parents on U.S. soil are automatically granted citizenship.

The court's recent decision continues a legal tradition that has remained largely settled for over a century, though it has become increasingly contested in recent years as immigration policy has moved to the forefront of national political debates.
