He is a US citizen being born in Fort Worth Texas. A better question for McCain would be “How can you justify having, as one of your advisors on Immigration issues, a former member of Mexico President Vincente Fox’s cabinet?”
Fox appointed Hernandez as a member of his cabinet ...I guess what is good enough for Fox is good enough for McCain.
Amazing. A US citizen serving in an official capacity as a close advisor to a foreign leader. How does a foreigner gain that level of trust from a foreign leader, I wonder?
