I never said that Trump said he wants to implement single payer in America. What he has said is that single payer “works incredibly well in Canada and Scotland” and that he says he will cover everyone and “the government will pay for it.”
Both are accurate, proven quotes. If one derives from that the idea that he wants to implement single payer in America, well, there is reason to infer that. He has never said that flat-out, and nobody has said he did. But it sounds like it may be his plan.
