An Oregon state judge faces an ethics hearing in November in connection with his refusal to perform same-sex marriages and several other allegations, a proceeding the judge on Tuesday called an unconstitutional assault on "core political speech."

In a 13-count statement of allegations, the state Commission on Judicial Fitness and Disability found no specific fault with Marion County Circuit Judge Vance Day's refusal to perform same-sex weddings — something he isn't required to do under county law. Day stopped performing any weddings earlier this year rather than preside over same-sex marriages.

The ethics panel, however, alleged that before he stopped performing marriages, Day — a former chairman of the state Republican Party — ordered his staff screen wedding applicants to ensure that they weren't of the same sex.

The complaint "fails to provide fair warning to judges like Judge Day that their unwillingness to perform non-mandatory, non-judicial duties because of sincerely-held religious beliefs is unconstitutionally vague under the First and Fourteenth Amendments of the United States Constitution."

The allegations against Day extend beyond the dispute over same-sex marriage. The most unusual one is that Day — who presides over the county's Veterans Treatment Court — hung a portrait of Adolf Hitler in the Marion County Courthouse.

"Three wall hangings were created and hung in July of 2014 to honor the service of a local medical doctor," according to Day's response. "One of the wall hangings emphasized how a liberal democracy overcame the scourge of fascism and, as part of the background behind [the doctor's] memorabilia, the wall hanging did contain an old painting from that period of Adolf Hitler."

The items were later removed, according to Day's response.

The 11 other allegations that will be heard at the hearing Nov. 9 in Salem, the state capital, include claims that:
