Note: The story says he had previously released his "hospital birth certificate" which apparently wasn't official. Trump resolved the matter with the release of the "official" certificate.
Trump should release everything he demands others release. That’s only fair and I’m a Trump fan.
“Trump refuses to release his birth or school records.”
Trump has. Cruz has not.
