The U.S. Conference of Catholic Bishops (USCCB) filed an amicus brief with the Supreme Court in late February 2026 arguing that Trump's executive order ending birthright citizenship for children of undocumented immigrants violates not only the Fourteenth Amendment but Catholic teaching on the inherent dignity of all persons. The brief described the order as forsaking "the vulnerable among us — specifically the children of migrants" and an affront to "the God-given equality of all people."
The USCCB filing represented a significant escalation in the bishops' ongoing confrontation with a president who explicitly claims the mantle of Christianity and Christian nationalism. The bishops had been repeatedly pushing back on administration policies since January 2025, but the Supreme Court brief marked the most formal and legally consequential expression of that resistance, directly challenging the administration before the court that Trump's appointments had substantially reshaped.
The episode illustrated a fracture within American Christianity that the administration's Christian nationalist posture had deepened: while evangelical and charismatic Protestant leaders largely supported Trump's agenda, the institutional Catholic hierarchy — nominally the religious tradition of many senior administration figures including JD Vance — increasingly positioned itself as a check on administration excess. The bishops' intervention underscores the contested nature of claims that administration policies reflect Christian values, complicating the ideological justification for religious-nationalist governance.
