At 11:20 a.m. in Washington, D.C., the Supreme Court was preparing to hear arguments in a case that could redefine the meaning of American citizenship, even as the personal histories of its nine members remind the nation of its immigrant past.
The dispute stems from President Donald Trump’s January 2025 executive order, part of his broader agenda to close the border. The order sought to end the guarantee that nearly all children born on U.S. soil automatically become citizens, regardless of their parents’ immigration status. Immigrant advocates, civil rights groups, and Democratic attorneys general immediately challenged the policy, and lower courts struck it down, citing the Fourteenth Amendment and longstanding precedent.
Chief Justice John Roberts, who will open the April 1 arguments and later lead the private vote, descends from English and Slovakian immigrants. His great‑great‑grandfather Richard Glover left England in 1863, driven by famine and political strife, and settled in Pennsylvania’s coal country. Roberts’ maternal line came from Hungary, also drawn to the steel hub of Johnstown. His family story reflects the struggles and aspirations of immigrants who sought opportunity in America.
Justice Clarence Thomas, the senior‑most associate justice, has written of his descent from West African slaves who lived in Georgia, South Carolina, and Florida. Raised in Pin Point, Georgia, by his maternal grandparents after his father left, Thomas often recalls his grandfather’s influence. His memoir, My Grandfather’s Son, captures the resilience that shaped his path, rooted in a heritage scarred by slavery yet defined by perseverance.
Justice Samuel Alito’s family came from southern Italy. His father was born in Calabria in 1914 and emigrated as an infant. The family name was “Americanized” at Ellis Island, reflecting assimilation pressures faced by many immigrants. Alito has spoken of his father’s poverty and struggles during the Depression, and of the scholarship that allowed him to attend college. His heritage remains central to his identity, celebrated in Italy where he was recently honored with an international prize.
Justice Sonia Sotomayor’s ancestry traces to Puerto Rico in the 1800s, when Spain controlled the island. Her parents migrated to New York during World War II, part of the first wave of Puerto Rican migration. Sotomayor has described herself as a “proud Nuyorican,” often reflecting on her family’s shifting fortunes and the cultural pride that continues to shape her voice on the bench.
Justice Elena Kagan’s family story is rooted in Russian Jewish immigration. Three of her grandparents arrived in the early 1900s, while the fourth was born in the U.S. to newly arrived parents. Raised in Manhattan, Kagan grew up in a Yiddish‑speaking household and was the first girl to participate in a bat Torah at her synagogue. She occasionally uses Yiddish phrases in her opinions, weaving cultural identity into her judicial voice.
Other justices connect to older immigrant waves or frontier experiences. Neil Gorsuch defines himself as a fourth‑generation Coloradan, emphasizing his family’s Western identity rather than immigrant ancestry. Brett Kavanaugh and Amy Coney Barrett trace their roots to Ireland and France, part of the broader story of European migration that shaped America. Justice Ketanji Brown Jackson has written of ancestors brought from Africa in bondage, underscoring the painful legacy of slavery.
At 11:20 a.m., the Court’s diverse heritage underscored the stakes of the case. The Fourteenth Amendment, adopted in 1868 after the Civil War, declares: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens.” For more than 150 years, that promise has defined the nation’s identity.
Public reaction has been intense. Immigrant advocates argue that ending birthright citizenship would dismantle a cornerstone of democracy. Supporters of Trump’s order contend it would strengthen sovereignty and reduce incentives for illegal immigration. The case has already ignited fierce debate across communities and political lines, with implications for the 2026 election.
Veteran Supreme Court journalist Joan Biskupic has noted how the justices’ family histories mirror the immigrant journeys now at stake. Her reporting emphasizes how their personal vantage points and ideological approaches will shape deliberations on whether birthright citizenship endures.
As arguments begin on April 1, the justices’ own ancestral journeys stand as silent testimony to the stakes of the case. Their ruling will not only shape immigration policy but also define how America tells its story to the world. The question before them when does one become an American will echo across generations.
