Cruz released his CA BC and he released his Mom's BC. There is nothing else to release. You're posting nonsense.
He could not use either of those documents to obtain a passport.
I'd like to see what document(s) he used to obtain his passport. Did he naturalize through the US Embassy in Canada, or did he file a form with the US Department of State to obtain a Report of Birth Abroad?
Those forms contain information on the citizenship, names etc of both parents. Place of birth, and the means by which citizenship was conferred.
