The U.S. Conference of Catholic Bishops filed an extraordinary amicus brief on Thursday urging the Supreme Court to strike down President Donald Trump’s executive order abolishing birthright citizenship for the children of many immigrants. The conference, which represents active Catholic bishops in the United States, frequently supports conservative positions at the court: In the past, it has argued against same-sex marriage, transgender rights, LGBTQ+ nondiscrimination laws, reproductive freedom, restrictions on school prayer, and medical aid in dying. But the conference is staunchly opposed to Trump’s draconian immigration policies. And its brief in support of birthright citizenship is a searing, full-throated rebuke of the president’s executive order as an affront to the God-given equality of all people.
