The Supreme Court appeared to be deeply skeptical of President Donald Trump's attempt to overturn more than a century of settled law around birthright citizenship. The court's conservative majority, including Chief Justice John Roberts and Justices Neil Gorsuch, Brett Kavanaugh and Amy Coney Barrett, questioned the historical, textual, and practical foundations of the Administration's position. Their exchanges with Solicitor General D. John Sauer suggested that the case could redefine who qualifies as an American citizen. The issue is the meaning of the Citizenship Clause of the 14th Amendment, which guarantees citizenship to nearly anyone born in the country with narrow exceptions. The order, part of a broader immigration crackdown, has been blocked nationwide by lower courts and never taken effect.
