"We've been waging all-out war on American democracy," said Trump on the weekend, but Snopes thinks he said something else and meant to say something else again (something that made sense), so the Fact-Checking website thinks that's enough to deny Trump said what he said, and we're supposed to interpret what he meant to say instead.
Lost yet? Yeah, me too.

To our ears, Trump unambiguously said, "we've been waging all-out war in American democracy" (and CSPAN's transcript reflects the same). We did not hear, nor does the context support the claim that he said, "We've been waging an all-out war on American democracy." It's clear that Trump was out to accuse his political opponents of waging war, not himself. Given the context, Trump likely meant to say, "They've been waging an all-out war on American democracy," but those weren't the words that came out of his mouth.
Twitter was having none of their bullshit.
