The Week in Review

The Week in Review with Joel Weisman

This week on Chicago Tonight: The Week in Review, the tone turns nasty in the final days of the mayoral campaign. In a rally for Gery Chico, a union leader calls Rahm Emanuel a "Wall Street Judas." Mayor Daley says that's anti-Semitic. But Chico, who has three Jewish daughters, disagrees. Just weeks after a major income tax increase, Gov. Pat Quinn's $52.7 billion budget includes tough cuts and billions in borrowing. And in sports, Super Bowl Bears great Dave Duerson is found dead. Blackhawks Coach Joel Quenneville is hospitalized. And the Bulls beat the league's best.
