You mean the same senator Howard that specifically said it did NOT apply to foreigners, aliens, or diplomats? And also said it was so discussed at the time he felt he didn’t even have to reiterate that?
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 person.
You’re misreading that statement. It’s not a list of classes, it’s a list of adjectives describing a single class - the children of diplomats.
This is that, in context:
“This amendment which I have offered, is simply declaratory of what I regard as the law of the land already, 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.”
