You state the answer and still can't see it. As in many cases when interpreting the Constitution, the meaning of the words aren't clear and therefore require interpretation.
Gee, I wonder if there is a source of information regarding the meaning of the words that were written to clarify the meaning. Hmm. It couldn't be the record of what the framers intended, could it? Nah, that makes no sense. When the meaning isn't clear, it obviously means whatever you really, really, really want it to mean. It's right there in black letters!
And if you still don't believe me, don't look at any material from the framers of the law! No, look at material from England way, way, way before the framers crafted the law. That's true black letter right there!
It is in English. Historic language knowledge is necessary.
It couldn't be the record of what the framers intended, could it?
No, it couldn't.
"A Matter of Interpretation," Federal Courts and the Law, by Antonin Scalia, 1997. This book contains an essay by Antonin Scalia and responses to that essay by professors Ronald Dworkin, Mary Ann Glendon, Laurence Tribe, and Gordon Wood. There is a final response by Antonin Scalia.
Laurence Tribe, pp. 65-6
Let me begin with my principal area of agreement with Justice Scalia. Like him, I believe that when we ask what a legal text means — what it requires of us, what it permits us to do, and what it forbids — we ought not to be inquiring (except perhaps very peripherally) into the ideas, intentions, or expectations subjectively held by whatever particular persons were, as a historical matter, involved in drafting, promulgating, or ratifying the text in question. To be sure, those matters, when reliably ascertainable, might shed some light on otherwise ambiguous or perplexing words or phrases - by pointing us, as readers, toward the linguistic frame of reference within which the people to whom those words or phrases were addressed would have "translated" and thus understood them. But such thoughts and beliefs can never substitute for what was in fact enacted as law. Like Justice Scalia, I never cease to be amazed by the arguments of judges, lawyers, or others who proceed as though legal texts were little more than interesting documentary evidence of what some lawgiver had in mind. And, like the justice, I find little to commend the proposition that anyone ought, in any circumstances I can imagine, to feel legally bound to obey another's mere wish or thought, or legally bound to act in accord with another's mere hope or fear.
Antonin Scalia, responding to Dr. Tribe, p. 133
He is correct that we both regard as irrelevant the intentions of the drafters....
Beginning on page 30 Scalia writes:
Extensive use of legislative history in this country dates only from about the 1940s. It was still being criticized by such respected justices as Frankfurter and Jackson as recently as the 1950s. Jackson, for example, wrote in one concurrence:I should concur in this result more readily if the Court could reach it by analysis of the statute instead of by psychoanalysis of Congress. When we decide from legislative history, including statements of witnesses at hearings, what Congress probably had in mind, we must put ourselves in the place of a majority of Congressmen and act according to the impression we think this history should have made on them. Never having been a Congressman, I am handicapped in that weird endeavor. That process seems to me not interpretation of a statute but creation of a statute.

Plyler v. Doe, 457 U.S. 202, 211 (1982)
In appellants' view, persons who have entered the United States illegally are not "within the jurisdiction" of a State even if they are present within a State's boundaries and subject to its laws. Neither our cases nor the logic of the Fourteenth Amendment supports that constricting construction of the phrase "within its jurisdiction." 10We have never suggested that the class of persons who might avail themselves of the equal protection guarantee is less than coextensive with that entitled to due process. To the contrary, we have recognized that both provisions were fashioned to protect an identical class of persons, and to reach every exercise of state authority.

10 "Although we have not previously focused on the intended meaning of this phrase, we have had occasion to examine the first sentence of the Fourteenth Amendment, which provides that "[a]ll persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States .... ." (Emphasis added.) Justice Gray, writing for the Court in United States v. Wong Kim Ark, 169 U. S. 649 (1898), detailed at some length the history of the Citizenship Clause, and the predominantly geographic sense in which the term "jurisdiction" was used.
He further noted that it was "impossible to construe the words 'subject to the jurisdiction thereof,' in the opening sentence [of the Fourteenth Amendment], as less comprehensive than the words 'within its jurisdiction,' in the concluding sentence of the same section; or to hold that persons 'within the jurisdiction' of one of the States of the Union are not 'subject to the jurisdiction of the United States."' Id., at 687.
Justice Gray concluded that "[e]very citizen or subject of another country, while domiciled here, is within the allegiance and the protection, and consequently subject to the jurisdiction, of the United States." Id., at 693. As one early commentator noted, given the historical emphasis on geographic territoriality, bounded only, if at all, by principles of sovereignty and allegiance, no plausible distinction with respect to Fourteenth Amendment "jurisdiction" can be drawn between resident aliens whose entry into the United States was lawful, and resident aliens whose entry was unlawful. See C. Bouvé, Exclusion and Expulsion of Aliens in the United States 425-427 (1912).
Conroy v. Aniskoff, 507 US 511, 519 (1993), Scalia, J., concurring
The greatest defect of legislative history is its illegitimacy.We are governed by laws, not by the intentions of legislators. As the Court said in 1844: "The law as it passed is the will of the majority of both houses, and the only mode in which that will is spoken is in the act itself...." Aldridge v. Williams, 3 How. 9, 24 (emphasis added). But not the least of the defects of legislative history is its indeterminacy. If one were to search for an interpretive technique that, on the whole, was more likely to confuse than to clarify, one could hardly find a more promising candidate than legislative history. And the present case nicely proves that point.
Judge Harold Leventhal used to describe the use of legislative history as the equivalent of entering a crowded cocktail party and looking over the heads of the guests for one's friends.
Aldridge v. Williams, 44 U.S. 9, 24 (1845)
In expounding this law, the judgment of the Court cannot in any degree be influenced by the construction placed upon it by individual members of Congress in the debate which took place on its passage nor by the motives or reasons assigned by them for supporting or opposing amendments that were offered. The law as it passed is the will of the majority of both houses, and the only mode in which that will is spoken is in the act itself, and we must gather their intention from the language there used, comparing it, when any ambiguity exists, with the laws upon the same subject and looking, if necessary, to the public history of the times in which it was passed.
United States v Union Pacific Railroad Company, 91 U.S. 72 (1875)
In construing an act of Congress, we are not at liberty to recur to the views of individual members in debate nor to consider the motives which influenced them to vote for or against its passage. The act itself speaks the will of Congress, and this is to be ascertained from the language used. But courts, in construing a statute, may with propriety recur to the history of the times when it was passed, and this is frequently necessary in order to ascertain the reason as well as the meaning of particular provisions in it. Aldridge v. Williams, 3 How. 24; Preston v. Browder, 1 Wheat. 115, 120 [argument of counsel -- omitted].
Downes v. Bidwell, 182 U.S. 244, 254 (1901)
In expounding this law, the judgment of the Court cannot in any degree be influenced by the construction placed upon it by individual members of Congress in the debate which took place on its passage nor by the motives or reasons assigned by them for supporting or opposing amendments that were offered. The law as it passed is the will of the majority of both houses, and the only mode in which that will is spoken is in the act itself, and we must gather their intention from the language there used, comparing it, when any ambiguity exists, with the laws upon the same subject and looking, if necessary, to the public history of the times in which it was passed.
