First problem is that there is no US code statute related to any crime called “collusion” so the entire criminal investigation was founded on a hoax created by the IC and media. At the time Mueller was appointed the entire investigation was a counter intelligence operation and he had no legal authority to investigate anything. The Rosenstein document that created the Special Prosecutor does not name a specific crime and only authorized an illegal fishing expedition.
To see was real criminal campaign violations with a foreign government look like you need to go back to the Bill Clinton campaign and the laundering of millions in Chinese government money or the secret meetings Ted Kennedy held with the Kremlin to cooperate on blocking Reagan’s second term.
