Special Counsel Robert Mueller is singing Michael Flynn's praises for spilling the beans on the Trump campaign/administration's dealings with Russia.
Beyond that, Mueller has kept the details to himself.
Former national security adviser Michael Flynn provided "substantial assistance" in special counsel Robert Mueller's Russia investigation, according to court papers filed Tuesday.
Prosecutors described Flynn's cooperation with federal prosecutors in a sentencing memo filed by Mueller that offered few new details of the Russia probe. Citing the extent of Flynn's cooperation, Mueller's office said a sentence that includes no prison time is "appropriate and warranted."
Flynn pleaded guilty in December 2017 to a charge of lying to the FBI about his conversations with Russian ambassador Sergey Kislyak in the weeks before Trump took office.
The crime carries a maximum sentence of five years in prison and a fine up to $250,000, but his plea agreement says he's eligible for a sentence of six months or less and can request the court not to impose a fine.Mueller's submission can be read here although it is heavily redacted. What remains boils down to - he was very helpful.
