Joe Berrios believes he’s free to hire whomever, even his dog.
That’s the way a political adviser to Berrios — the Cook County assessor and county Democratic Party chairman — once explained it to me.
That’s why his sister Carmen Berrios was working one evening in April 2007, after normal business hours, at the Cook County Board of Review. That was back when her brother was still one of the tax-appeal board’s three elected commissioners, before he left to successfully run for assessor — bringing his sister and other relatives with him to his new public office, despite county ethics rules barring nepotism hiring.
