Federal prosecutors on Tuesday said they did not oppose Rick Gates’ request for a sentence of probation on charges brought by the special counsel’s office, as they commended the former top Trump campaign adviser’s “extraordinary assistance” with the investigation into Russian interference in the 2016 election.

In a court filing ahead of his sentencing next week, prosecutors said Gates deserves a “significant downward departure” from guidelines that would otherwise call for him to serve about four years, or longer, in prison.
