There is a lot of additional information available regarding this case, but the original source is from FBI documents. An investigation into Russian corruption and collusion took place in 2009, and was then covered up by Meuller and Co. There were tens or hundreds of millions in kickbacks floating around to the Clinton Foundation and Podesta Lobby firm, and whoever else was involved. A whole lot of people are going to be in a heap of crap over this if they can't manage to pull off another cover up, i.e. something like the Trump/Russia collusion thingy?
