The remarks of Mr. Bingham and of Senator Pinckney, by well-recognized and objective judicial principles of statutory interpretation are mere "legislative history" relevant and cognizable by the courts ONLY where there is some facial ambiguity in the language of the enactment itself (i.e. the 14th Amendment). Otherwise the law (the 14th Amendment in this case) says what it means and means what it says regardless of Congressional intent.
Also, there are privately employed American citizens who are effectively permanently residing in other nations who nonetheless enjoy the same rights as any other citizen. The execrable Lowell P. Weicker, Jr., was born in Paris, France, to parents who were American citizens in Paris on business. The late George Romney was born in Mexico in circumstances suggesting his parents' intention to remain there in protest of Congressional requirements that Utah outlaw polygamy as a condition ofd admission as a state to the Union. Each ran unsuccessfully for President but citizenship was not seriously questioned in either case.
“Otherwise the law (the 14th Amendment in this case) says what it means and means what it says regardless of Congressional intent.”
Ignoring “original intent” is the reason so many good things have been preverted to bad things in regards to both the constitution and laws enacted.
