Releasing his mother’s birth certificate makes perfect sense. The natural born citizenship issue is what is being contested, not the parentage of Cruz. He can offer, if necessary, any number of other exhibits to show he was born to Eleanor Cruz. But the NBC question hangs, in large part, on whether she was locked in as a U.S. Citizen when he was born. Her birth certificate shows this to be true, and that would be why he released it.

His birth certificate doesn't address his mother's citizenship. It addresses her place of birth which may be why he chose that document.
So you’re saying Cruz doesn’t possess a CRBA?
