Rochard here's you a good read about how Fusion GPS worked together with Russia to try and kill the Magnitsky Act. You should be ok with the source..

So there we have it. Russia meddled in the election alright via Fusion GPS. Putin actually wanted Hillary to win because she was opposed to the Magnitsky Act whereas Trump was for it. (his quote during the election is somewhere in those 3 articles.)
Also make note of what Fusion GPS' modus operandi is. It's creating fake dossier's on those who are opposed to their clients, using it as a bargaining chip and either making and/or killing news stories. They use a law firm to get paid so their clients are kept secret due to attorney client privilege..
