NBC News reports:
The Justice Department’s Office of the Inspector General has begun investigating the circumstances surrounding the sentencing recommendation for Roger Stone, a longtime friend of President Donald Trump, according to two sources familiar with the matter.
The investigation is focused on events in February, according to the two sources who spoke on the condition of anonymity, when prosecutors for Stone have said they were told to seek a lighter sentence for Stone than they had previously considered.
Attorney General William Barr ultimately intervened to override the prosecutors’ recommendation of seven to nine years and ask for a lighter sentence. All four prosecutors quit the case as a result.
