The supreme court has already ruled on this. children born in the US are US citizens, they cannot have their citizenship revoked because of the crimes of their parents.Actually that's according to a court ruling, not according to the US constitution. The 14th Amendment was not intended to make the children of illegal aliens or tourists US citizens. The fact that John McCain is a natural born US citizen makes this quite clear.
if we can punish people for the crimes of their ancestors then this opens up a whole new argument for Slave Reparations
