The short version? Mueller is done. His report unambiguously states there was no collusion or obstruction. He was allowed to follow every lead unfettered in an investigation of breathtaking depth.
It cannot be clearer. The report summary states, “The Special Counsel’s investigation did not find that the Trump campaign or anyone associated with it conspired or coordinated with Russia in its efforts to influence the 2016 US Presidential Election…the report does not recommend any further indictments, nor did the Special Counsel obtain any sealed indictments that have yet to be made public.”
Robert Mueller did not charge any Americans with collusion, coordination, or criminal conspiracy between the Trump campaign and Russia. The special counsel also considered whether members of the Trump campaign “coordinated,” a much lower standard defined as an “agreement, tacit or express,” with Russian election interference activities. They did not.
