Even though another member of Green Bay’s governing body says his comments and conduct violate an ethical standard, Alderman Guy Zima says he’s not changing.  Alderwoman Barb Dorff points to Zima’s comments at city hall meetings last year.  He has called Green Bay Economic Development Director Kevin Vonck “Doctor Yahoo,” and called the mayor a “weasel.”  Zima says, “The truth is the truth,” adding the mayor doesn’t answer questions directly sometimes.  He says Dorff won’t turn him into what he calls a “politically correct wimp.”  Zima says he wouldn’t change 99 percent of what he has said.
