Ald. Sandi Jackson was one half of a major political power couple.
Her husband, Jesse Jackson Jr., resigned from Congress in November amid a federal investigation and health issues. Now the alderman is leaving her post, as well.
Reaction from elected officials, constituents and friends was swift following the Friday afternoon announcement.
Chicago Mayor Rahm Emanuel:
"As Sandi takes this time to focus on her family, we give her out deepest thanks and support for her service to our city and the residents of her ward."
