A Natural Born citizen can not be created by an act of naturalization. Congress has the authority to naturalize. Any person so naturalized by congress is immediately not a natural born citizen and, thereby, ineligible to be POTUS. A natural born citizen is created by nature. Nature has determined that Ted Cruz is a natural born citizen of Canada. Congress determined that he is a naturalized citizen of the United States.
Nope - no naturalization process was need for TC to be a citizen = NBC.
