If Mueller and Rosenstein can't show how Manafort, Gates, and Pedestal were implicated during his investigation of Russian interference with the 2016 election, then this is becoming an abuse of power. I've wondered if Mueller's team is on a mission to prosecute all those that were being investigated during the Uranium One Deal but was unable to indict them because Mueller was told not to pursue it. Indictments would derail Obama's political agenda for the Russian "reset". Now he is in the position to bring justice to all those involved in that morass. I know this is purely speculation, but can imagine such a scenario. I find it hard to believe Mueller would have gathered all that evidence of bribery, extortion, money laundering etc. and concluded only one guy should be charged with one count of money laundering four years later. Mueller had to be directed to stand down. I can't imagine that set well with him.
