No, it has to be interpreted in terms of what he said. He was explicit about what he said: “I’m not talking about the neo-Nazis and the white nationalists, because they should be condemned totally.” Nobody operating in good faith could interpret that as ambiguous.
At most Trump was mistaken about who else was in the park. Be repeatedly said that “there were protesters who were there to protest the taking down, of to them, a very, very important statue and the renaming of a park from Robert E. Lee to another name.” Maybe he was wrong about that fact.
> He had one job, to condemn the Unite The Right protest,
But that’s your real argument, isn’t it? That it was insensitive of Trump to address the larger context of the protests (which was about tearing down confederate statues) instead of just sticking to condemning the neo-Nazis. Maybe that’s true. But it’s utterly dishonest—a point-blank lie—to say that he didn’t condemn neo-Nazis and white supremacists when he did, using those exact words.
