In the run-up to the Trump-Putin summit, many wondered how the Mueller investigation's latest indictment would impact the outcome. After all, the language of the indictment was very specific and very detailed. Russian intelligence officers were mentioned by name. More to the point, the indictment revealed that Russian hackers were inside the computer systems of the Democratic National Committee for far longer than we knew. They had access to the DNC's analytics, their data on voters and opponents.
Russians certainly would have used that data to run their own online campaigns, using the fake social media accounts that special counsel Robert Mueller revealed in a previous indictment.
