News from CA: "Santa Ana Mayor Had City Hall Meeting That Could be Illegal"

Quoted in this one in the Voice of the OC. 

Jessica Levinson, an associate professor at Loyola Law School, said one documented instance of using the office for a personal business meeting probably would lead to only a civil fine.

It could, however, also turn into a criminal issue if more instances are uncovered, Levinson said. “If you are running a consulting business out of the mayor’s office, there is a possibility for criminal liability,” she said.
