Is there any issue with judges reading newspaper articles about cases they're in? I know that jury members aren't supposed to, are judges fine?
(The reference is to the President's statements before and after the election)
Many seem to be surprised reading this transcript. Yet the tone this judge is using isn't anything special. You can see that he takes extreme care not to disadvantage one side, without pretending to be some sort of soulless automaton.
Judges are supposed to be people who can be trusted to be objective. They are chosen (or, before they were elected, and politics became divisive) for their trustworthiness and objective scholarship. Historically they were well educated, of a higher class, perceived to be of a higher moral character.
The point is judges are expected to be mostly objective, and use external information responsibly.
