Justice Ketanji Brown Jackson criticizes Justice Clarence Thomas in connection with a Supreme Court dispute over birthright citizenship under the 14th Amendment. Multiple reports say Jackson, writing in a concurring opinion, argues that Thomas’s position in a case about whether children born in the United States to certain noncitizen parents are entitled to citizenship echoes the reasoning of the Dred Scott v. Sandford decision, a historically racist ruling from the 19th century. The accounts reference the Supreme Court ruling in Trump v. Barbara, which holds that removing birthright citizenship from U.S.-born children of illegal aliens would violate the 14th Amendment. Jackson’s criticism is directed at Thomas’s principal dissent, which advocates a narrower view of the constitutional citizenship guarantee. In the reports, Jackson describes Thomas as seeking to return to what she characterizes as a core tenet of the Dred Scott framework, positioning the disagreement as one rooted in fundamental constitutional principles rather than a limited technical question. The sources focus on Jackson’s comparison to Dred Scott and the disagreement between Jackson and Thomas over the meaning and application of the 14th Amendment’s citizenship clause.
