Mueller has referred a whopping 14 additional potential criminal cases to other offices

Special Counsel Robert Mueller's report has investigation has finished, but the probe has spurred more than a dozen possible criminal cases to be examined in other offices of the Justice Department.
According to the report published Thursday, Mueller has referred out information about 14 additional instances of potential or actual criminal activity, of which only two or three are publicly known.
Twelve of the cases are redacted in the report, while two are public:
First, the report notes that Michael Cohen's banking and fraud crimes, to which he has pleaded guilty, were referred out to the Southern District of New York. Crucially, the SDNY also uncovered Cohen's participation in a campaign finance violation that involved illegal hush money payments — a crime in which President Donald Trump has been directly implicated.
Second, Mueller referred out the case relating to Greg Craig, a former White House counsel for President Barack Obama, and his potential foreign lobbying efforts. Charges have been filed by Craig about his alleged lies to investigators, though he is fighting the indictment. This case also related to Craig's law firm, Skadden, Arps, Slate, Meagher & Flom LLP, and an apparent unnamed individual.
Because the rest of the report seems to redact much of the information regarding Roger Stone to protect an ongoing maatter, it's reasonable to assume that another of the cases referred out relates to him. Stone is facing charges for lying, obstructing justice, and intimidating a witness that were brought by Mueller.
But the other cases — and who they might relate to or implicate — remain a mystery.
In his public comments about the case, Attorney General Bill Barr seemed to downplay the extent of the investigations that were referred out, claiming that Mueller "referred several matters to other offices for further action." "Several" is a vague word, but it's rarely used to mean a dozen or more.
