Is there any actual evidence that his was Russia? All I've seen so far is solarWinds unsubstantiated claim.
For a very good reason.
Russia is in NO uncertain terms a hostile and aggressive nation that we all need to be wary of.
Not that Russia is not a threat to the US, but there is a sizable part of the federal bureaucracy that wants to pin things on Russia for various reasons (it's not all anti-Trump either).
Edit: Downvoters, feel free to prove me wrong. Here's one source for my claims[0]
