Did we ever find out what other criminal investigations Mike Flynn was providing significant assistance?
The court papers offered few new details on the Russia probe but the prosecutors, citing Flynn's extensive cooperation in "several ongoing investigations," said a sentence that includes no prison time is "appropriate and warranted."
Flynn's cooperation extends to a "criminal investigation" that is separate from Mueller's probe, according to the court documents. But the federal prosecutors released no details on that investigation, redacting nearly the entire section devoted to it.
