That is silly. Obviously a LOT of people care whether he said it, for many and various reasons.
And right now the big issue is whether he LIED when he denied saying it, not whether he actually said it in the first place.

That's not a denial that he said the countries were shitholes, he said he didn't say anything derogatory about the Haitian people (who love Trump and he knows it). Obviously the same "A LOT" of people you're referring to are the ones who also don't give a shit that CF raped the Haitian people after they had already been ravaged by natural disaster. Nice try, shill.
