Sure Russia meddled, China too. Likely a few other "bad actors" as well, both inside the country and out.  Just as we meddle with them. Just as they have meddled in the past. 
Who had responsibility to prevent the meddling?  Not President Elect Trump. Just another Obama administration failure. 
I have yet to see any evidence showing that it had any affect on the outcome of the election. Frankly, these ongoing efforts to delegitimize the duly elected President of the United States are beginning to seem a bit treasonous. 
Bad actors like Podesta and Reid might want to think about that.
 There is no positive outcome to be had here for the Dims. They look inept and desperate no matter how this plays out.
