Yes, Russian, or anybody else's, interference in US domestic politics is unwelcome and needs to be prevented. A serious investigation is in order and the results should be properly evaluated. On the other hand, the following are unwelcome from anyone: seeing Russia primarily from the perspective of US domestic politics, hyperventilating for dubious short-term domestic political gain over an intelligence question where the facts remain unknown, likely to be less than conclusive, and unknowable for the time being, failing to recognize that Russia may be adversarial in some areas but not in others and that good long term relations are in the interest of both Russia and the US, as well as Europe.
In what ways is Russia adversarial to the US?
I don't know how it will go but we all need better cyber protection, not only from Russia but also the US government, China, France, Germany, UK, Persia, Israel, ISIS and anyone else who is into cyber spying and mischief.
