Nonsense. Democrats never talked about ill-defined "Russian interference" until after Trump was elected, and have yet to produce anything that is even claimed to be evidence, or to name specific persons, other than boogie-man Trump of course, who might have been involved in whatever vague actions they have not quite claimed to have happened.
Republicans have transcripts and have made calls for Susan Rice and Farkas to explain their very specific statements and actions.
The Obama administration assumed Hillary Clinton was going to win the election, so all of the evidence of this illegal surveillance was going to disappear. When Trump won, they knew they were all going to get caught with their pants down, so to speak -- so they fabricated the story about Russia's ties to the Trump campaign in order to rationalize the surveillance.
