Rubio’s parents were not citizens at the time of his birth....and with the legal precedent already set in about 80 different court cases....to be natural born one must also have citizen parents at time of birth
Note that the ones who inaccurately claim Marco Rubio is eligible are the same ones that fought against conservatives on Obama Eligibility.
I think I will go with the opinion of constitutional scholars like Mark Levin on this one. Rubio was born in Miami, Florida. That makes him a natural born citizen. The citizenship status of his parents is irrelevant. The courts are not going to agree with you any more on Rubio than they did on Obama. Rubio is constitutionally eligible to hold the office of President (or VP). Period. The end.
