Candidate for Chicago mayor Toni Preckwinkle is trying to distance herself from Alderman Ed Burke after he was charged with attempted extortion last week. In a Twitter post last night, the Cook County Board president said she is returning 116-thousand dollars raised at a campaign fundraiser at Burke’s home last January. Preckwinkle also said she’s removing Burke as chair of the Cook County Democratic Party Judicial Slating Committee and demanded that he resign from the City Council and as the 14th Ward’s Democratic committeeman. The longtime alderman is accused of using his powerful position to solicit business for his private tax law firm.
