Only ignorant people are worried about this. Special Investigator Mueller employed 19 lawyers. These lawyers were assisted by a team of approximately 40 FBI agents, intelligence analysts, forensic accountants, and other professional staff. The Special Council issued more than 2800 subpoenas, executed nearly 500 search warrants, obtained more than 230 orders for communications records, issued almost 50 orders authorizing the use of pen registers, made 13 requests to foreign governments for evidence, and interviewed approximately 500 witnesses. 37 indictments, 4 prison sentences. After 675 days, not a single American was found to have committed any conspiracy, or collusion to interfere with the 2016 Presidential election. AG William Barr and Deputy AG Rod Rosenstein (who appointed Robert Mueller) wrote the 4 page summary noting that no collusion was found and that there was not enough evidence to find any obstruction of justice.
