Christine Beatty, former chief of staff to ex-Detroit Mayor Kwame Kilpatrick, begins her county jail sentence next week. Kilpatrick is serving 120 days after admitting that he lied under oath about an extra-marital affair with Beatty when the city was sued by two former cops whose investigation could’ve exposed the romance. Beatty pleaded guilty to similar charges last month after many had speculated that she’d agree to testify against Kilpatrick and avoid jail time. Beatty resigned as chief of staff when the Detroit Free Press published dozens of sexually explicit text messages exchanged between her and Kilpatrick.
