I have heard that Cruz has sealed some documents.
IF true, why would that be necessary?
Why not? Our Kenyan-communist did it.
Sauce=goose=sauce=gander.
Cruz has access to his own records, of course (as you do to yours), and can make them public if he wants. Since there is no official "vetting" of qualifications for office, he can hide his history, with pressure coming only when the public has doubts.
His admitted birth in Canada makes him naturalized. There is no need to see any records. Just "see law."
