The entire US political establishment invested so much of its credibility into "Mueller will prove Trump is a Russian spy" that are you really surprised nobody cares what the US Government thinks anymore? There have been non-stop stories about Russia for years that always collapse.

Anyway, the idea that there was a huge campaign to "denigrate Clinton" from Russia is absurd on its face. She had most of a country trying to denigrate her during that election. Trump won because so many people hated Clinton even more than they disliked Trump.
