Former national security adviser Michael Flynn has provided “substantial” aid in the Russia investigation and beyond — and that merits a judge’s consideration at Flynn’s sentencing this month, prosecutors said in court papers late Tuesday.

The government said in a memo to a federal judge that it believes sentencing for Flynn should be lenient and that even a sentence without prison time “is appropriate and warranted.”
