Yeah, how come the 14th didn't cover these Americans?
Indian Citizenship Act
The text of the 1924 Indian Citizenship Act (43 U.S. Stats. At Large, Ch. 233, p. 253 (1924)) reads as follows:
BE IT ENACTED by the Senate and house of Representatives of the United States of America in Congress assembled, That all non citizen Indians born within the territorial limits of the United States be, and they are hereby, declared to be citizens of the United States: Provided That the granting of such citizenship shall not in any manner impair or otherwise affect the right of any Indian to tribal or other property."
Approved, June 2, 1924. June 2, 1924. [H. R. 6355.] [Public, No. 175.]
That is because the first item of the 14th reads as follows.
Section 1. All persons born or naturalized in the United States, AND subject to the jurisdiction thereof, are citizens of the United States and of the State ...
Note the red line as it reads two illegal aliens are NOT subject to the jurisdiction (nor is anchor baby) of the U.S. AND is the keyword that reveals the true meaning of the wording or the wording would have been OR. "AND" implies somebody can be born or naturalized in the United State and NOT be subject to the jurisdiction of.
