The only thing the Russians did in regards to the 2016 elections was they hacked members of the DNC and released a bunch of emails via Wikileaks that basically confirmed what everyone already knew - the DNC and their buddies in the media and government were in the tank for Hillary all along, and it blew up in their faces when Trump won.
It should be noted there's no proof Russia even did it. The FBI never investigated the servers. It was "investigated" a third party that is pro-Democrat and anti-Russia.
I think Russia hacking the DNC is an even bigger lie than WMDs.
