On May 17, 2017, the Justice Department named former FBI Director Robert Mueller as special counsel to oversee the investigation into Russian government efforts to influence the 2016 presidential election, “and related matters.”

"My decision is not a finding that crimes have been committed or that any prosecution is warranted. I have made no such determination. What I have determined is that based upon the unique circumstances, the public interest requires me to place this investigation under the authority of a person who exercises a degree of independence from the normal chain of command," Deputy Attorney General Rod Rosenstein said in making the announcement.

Throughout the length of the appointment, Mueller has been notoriously tight lipped while delivering at least two dozen indictments of Russian operatives and some individuals close to the Trump campaign, including former campaign director Paul Manafort and Trump associate Roger Stone.
