Define "interfering".  There never has been a definition of that term regarding this stupid made up baloney.  "Meddling" is another term that means nothing.  The only thing identified is one show, on RT (Russian Television) that was not favorable to Hillery, who, by the way, was saying we needed to go to war with the Russians.  Of course Putin was not for her.  
What this is really all about is that the democrats knew for months that Trump was going to win, and that she was losing.  They knew the polls were rigged, it was all in the method section in each poll....over sampling democrats by up to 50%, etc.  More women than men.  Hardly any republicans, etc.  Even then, Trump would lead in many polls in certain areas.  So, the dems concocted this ridiculous story about the Russians to do two things:
1.  cover their tracks for Hillary and Uranium 1
2.  use this story to hurt Trump after the election.  They wanted to blame the Russians for her loss.  Only a fool would believe in this crap.
