If you want to make it so that some people born here are not "natural born citizens" you have to amend the Constitution.
Amendment XIV, Section. 1., states:
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 wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
and since when does congress care abut whether or not the laws they pass are constitutional? or are they gonna start here?
" If you want to make it so that some people born here are not "natural born citizens" you have to amend the Constitution."
WRONG
That is a novel interpretation.
"and subject to the jurisdiction thereof,"
...means what it says, lefty.
