Given that President Trump addressed the group, just about every new outlet covered the march - NPR, Washington Post, New York Times, CNN, etc. As for the 3 categories (A, B, C) listed above, I would add a 4th category: “objectively”. That is, as a news story, it can be reported and was reported by many outlets in a purely factual way, without implying any value judgments on the march itself, either positive or negative. But “not at all” does not apply since the march was covered.
