A district court judge in Washington, D.C., put out a rare statement dismissing the idea that outside pressure may influence judges’ decisions after President Trump weighed in on Roger Stone’s sentencing.

U.S. District Court Chief Judge Beryl Howell released a statement on Thursday defending the integrity of the judicial system. On Tuesday, the Justice Department announced it would seek a lower sentence than originally planned in the case of longtime Republican operative Roger Stone, causing the four prosecutors working the case to resign in protest.
