Sen. David Vitter is renewing his call to change the law so that U.S. citizenship is no longer granted automatically as a result of being born on American soil.

The Louisiana Republican, in an interview on CNN that was flagged by the Hill, said the U.S. is the only industrialized nation that treats citizenship as a birthright, regardless of the citizenship of a child’s parents. Vitter, who plans to run for governor next year, also was critical of apportionment regulations that he says count non-citizens as a part of the population in the drawing of congressional districts.
