From New Hampshire Judicial Ethics Opinion 2017-ACJE-01, decided in 2017 but just posted on Westlaw:
QUESTION PRESENTED:
Does the Code of Judicial Conduct prohibit judges from hosting podcasts or radio shows devoted to sports or other matters that have little to do with the courts, the law or the legal profession?
FACTS PRESENTED:
The judge has been asked to host a podcast, devoted to professional football, the New England Patriots and predictions for the games ahead. The podcast will be sponsored by a local commercial radio station. Although the podcast will not ordinarily touch on legal issues, there may be some discussion about NFL rulings, calls on the field and disciplinary actions.
