Is Cruz really a Canadian citizen? Is Kasich’s Trump’s running mate?
He was legally naturalized by virtue of his mothers USA citizenship, and as such, is a legal USA citizen.
If he hadn't sealed his records, this could have been put to bed last year, but he didn't, and it isn't.
Kasich is not Trump's running mate.
Nor will Cruz, Rubio, Bush, Christie, Carson or Romney be Trump's VP pick.
