Even though it though there is nothing illegal about her serving as a commissioner while working for the efforts of the state agency that the city has fled suit against, she should step down to prevent any chance of improprieties.
As a transportation commissioner what is there to prevent her from using her position to provide herself, her PR firm and HSR with info regarding city efforts re HSR. As a "city insider" she has easier access to coordinated efforts with other communities and an insiders read on the thinking, mores and strategies of those involved on the cities side. In a sense an HSR trojan horse.
