Barack Obama have brought his name into the national spotlight , was arrested Monday morning , an FBI spokesman said . Rezko was taken into custody by the FBI at his Wilmette , Illinois , home just outside Chicago following a government motion to revoke his bond , said FBI spokesman Tom Simon . Rezko -- whom Sen. Hillary Clinton referred to in a debate as having run a `` slum landlord business '' -- has pleaded not guilty to federal charges of conspiracy , influence peddling and demanding kickbacks from companies seeking Illinois state business .
