Here is the Congressional Record:

The sponsor of the 14th amendment (Jacob Howard) made it crystal clear that birthright citizenship was for everyone, excluding the children of foreign ministers and ambassadors for obvious reasons.
"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. It settles the great question of citizenship and removes all doubt as to what persons are or are not citizens of the United States."
Trump can't do jack shit about it.
