Mark Levin's remarks on this issue.
He then put up a quotationfrom Citizenship Clause author Senator Jacob Howard (R-MI) during the debate on the 14th Amendment that “Every person born within the limits of the United States, and subject to their jurisdiction is, by virtue of natural law and national law, a citizen of the [United States]. This will not, of course, include persons born in the United States who are foreigners, aliens, who belong to the families of ambassadors or foreign ministers, accredited to the government of the United States, but will include every other class of persons.”The clause speaks for itself, the author of the clause made it abundantly, unequivocally clear, let’s add another thing, let’s read the clause together, shall we? ‘All persons born or naturalized in the United States.’ Let’s stop there. If it means what the proponents of birthright citizenship say, it would stop right there. ‘All persons born or naturalized in the United States’ are citizens. There’s no need for anything else, but that’s what it says. Then it says, and, ‘subject to the jurisdiction thereof.’
