Read much, most won’t, so here is a nice slice for busy people...
“All from other lands, who by the terms of [congressional] laws and a compliance with their provisions become naturalized, are adopted citizens of the United States; all other persons born within the Republic, of parents owing allegiance to no other sovereignty, are natural born citizens. Gentleman can find no exception to this statement touching natural-born citizens except what is said in the Constitution relating to Indians.” (Cong. Globe, 37th, 2nd Sess., 1639 (1862)).
The above is a congressional declaration. I would assume that it carries a little more weight than Newsweek.
every human being born within the jurisdiction of the United States of parents not owing allegiance to any foreign sovereignty is, in the language of your Constitution itself, a natural born citizen. (Cong. Globe, 39th, 1st Sess., 1291 (1866))"
No other Representative ever took issue with these words on the floor of the House. If you read the Congressional Globe to study these debates, you will see that many of the underlying issues were hotly contested. However, Binghams definition of natural born citizen (born of citizen parents in the sovereign territory of the U.S.) was never challenged on the floor of the House. Without a challenge on the definition, it appears the ALL where in agreement.
Then, during a debate (see pg. 2791) on April 25, 1872 regarding a certain Dr. Houard, who had been incarcerated in Spain, the issue was raised on the floor of the House of Representatives as to whether the man was a US citizen (generally. they were not trying to decide if he was a NBC). Representative Bingham (of Ohio), stated on the floor:
As to the question of citizenship I am willing to resolve all doubts in favor of a citizen of the United States. That Dr. Houard is a natural-born citizen of the United States there is not room for the shadow of a doubt. He was born of naturalized parents within the jurisdiction of the United States, and by the express words of the Constitution, as amended to-day, he is declared to all the world to be a citizen of the United States by birth.
