His argument is not nonsense. Even assuming you buy the line that the media is not covering the story because it has "has all the hallmarks" of a Russian disinformation campaign as was argued by all the media outlets it makes no sense why they wouldn't cover it (unless your assume they are worried about how it might effect the election). Just months before the idea that a trump administration offical (or close personal adviser/lawyer) was working with a foreign power to effect the election was a impeachable offense! Now it's not even worth informing the public about?
