The article claims Don Jr. was promoting conspiracy theories, and indirectly suggests "crisis actor" as one of those theories. If you click through to the story they're sourcing from, it says much the same. It's only when you go down to the next level, to "The Hill," that you find Don Jr. didn't actually do that. He liked a comment that said Hogg was coached by his father, and a comment that said Hogg is actually promoting a conspiracy theory of his own.
