Aside from being factually wrong, Cruz Mother was in no way a Cuban nor an migrant what is your point ?
Cruz’s father was Cuban, and Cuba has/had a law that a person boran abroad of one citizen parent is a citizen of Cuba. At the moment of his birth, Ted was as much Cuban as American. Canada’s claim was even stronger, because he was born there of lawful permanent residents.
Never said Eleanor Darragh Wilson Cruz was Cuban nor a migrant.
