FWIW, people around here denied that the Saudis donated money to the Clinton Campaign, which they didn't and which would be 100% illegal. Trump's accusation is that they donated money to the Clinton Foundation (don't know but let's assume that's true), and that Clinton should return that money because Saudi Arabia is awful and does terrible things (100% true). I suppose there could be an interesting discussion there surrounding whether international charities should accept donations from "bad" countries like Saudi Arabia or its leaders and, if not, what constitutes a "bad" country, but I don't see how that would be considered the best moment of the debate.
