You said they had ethic rules. Please feel free to post them. However, one need not know the "rules" to know if something is ethical or not. It's not written down anywhere in my employee handbook, for example, that we aren't supposed to take money from patients for doing our jobs. But nobody in the building would think such an action would be ethical. Unless they are Trump supporters. They have no ethics. As you demonstrate daily. Are you still pretending you don't support the blob?
Judges shouldn't be taking gifts from folks who have a case the is before them.
