Actually, I believe that someone researched this, and he is legally able to keep his job even after losing his license to practice law. Does someone here have a link to that info? Howlin?
If he is no longer a practicing licensed attorney the state can have him removed from office as he would no longer be licensed to perform his job. Indeed for him to continue in that job would be a crime in and of itself, i.e., practicing law without a license.
So if he loses his license, he loses his job.
