In NYC mayors can't be impeached. The only legal way to remove a mayor in NY is by action of the govorner.
You keep acting like we are calling for imprisonment here, but this is literally the correct legal process to remove a corrupt mayor. By not removing him, the govorner is acting against the rule of law you seem to be so concerned about. It is more authoritarian to think he deserves to stay mayor despite betraying his people.
As I have told you he has to have the right to defend himself against the charges. He never faced a trial so he never has had an opportunity to defend himself.
I hate Mayor Adams. I wanted him sacked when he hired his brother to a job said brother was unqualified for in his first few days but there is a process to remove him and none of those steps have been met other than presenting the charge.
