This week on Chicago Tonight: The Week in Review, Mayor-elect Rahm Emanuel-backed candidates win big in Tuesday's aldermanic runoff election, and he also responds to emperor claims. Mayor Daley and Emanuel speak out against concealed carry legislation. Meanwhile, Caterpillar, one of the state's largest manufacturer's says it will stay put in Peoria. And in sports, the Cubs and Sox open the baseball season, while the Bulls look to finish strong -- and on top of the Eastern Conference.
