"I think Canada, what you said that, “Well, that one, I might be trolling.” But I'm really not trolling. Canada is an interesting case. We lose $200 to $250 billion a year supporting Canada. And I asked a man who I called Governor Trudeau. I said, ”Why? Why do you think we're losing so much money supporting you? Do you think that's right? Do you think that's appropriate for another country to make it possible, for a country to sustain and he was unable to give me an answer, but it costs us over $200 billion a year to take care of Canada?” We’re taking care of their military. We're taking care of every aspect of their lives, and we don't need them to make cars for us. In fact, we don't want them to make cars for us. We want to make our own cars. We don't need their lumber. We don't need their energy. We don't need anything from Canada. And I say the only way this thing really works is for Canada to become a state."
