Mueller (Special Council) Investigation On May 17, 2017, US Deputy Attorney General Rod Rosenstein appointed Robert Mueller to take over the FBI work (Hurricane Crossfire) to investigate Russian interference in the 2016 United States elections, potential links with the Trump campaign and “any matters that may arise”.  Thirty four (34) individuals were indicted  of which five (5) were Trump associates for process crimes (not related to Russian interference in the election). The investigation concluded on March 22, 2019 with an ambiguous report that claimed no Americans colluded with Russia on the 2016 election, but obstruction of justice charges by President Trump were not filed because a sitting president cannot be charged with a federal crime while in office. This left the final say with US Attorney General William Barr, who along with Rosenstein concluded that there was insufficient evidence for obstruction of justice and closed the matter with no further charges. The cost of the investigation was over $32 million dollars.
