Neither parents were illegal aliens, in fact both were in the US with the permission of the US Govt.
“Neither parents were illegal aliens...”
That isn’t relevant in this instance.
The question is whether the parents were citizens.
I.e., were they born here or had they sworn an oath of allegiance to the U.S. via a citizenship process?
Did you read the whole piece?
Rubio’s parents did not receive their naturalized citizenship until several years AFTER Rubio was born. Just because they are in the country “with the permission of the US Govt” does not make them naturalized citizens.
Rubio is NOT a natural born citizen.
