During his GOP presidential campaign, candidate Donald Trump triggered a debate over birthright citizenship. Now, some of the top high court advocates urge the U.S. Supreme Court to weigh in on what birthright citizenship means, particularly for persons born in U.S. territories.

Before the justices adjourn for the summer, they may consider whether to grant review next term in Tuaua v. United States. Lene Tuaua, four others born in American Samoa and the Samoan Federation of America ask the high court whether the Constitution’s citizenship clause entitles persons born in American Samoa—a U.S. territory—to birthright citizenship.
