By the way, the press seems to call this "meddling". Not "hacking" or "interference". Again, I don't even think this qualifies as "meddling," more like "fake news."
Mueller's scope was limited thank goodness but I question his findings. This is it? What about the Chinese? Nigerians? He can only find a handful of Russians? I think the Social Media companies helped him out. No NSA, CIA, FBI, etc assistance.
