Pension fund investment firms paid big bucks to Rahm Emanuel's campaign

international Business Times - Executives at investment firms that manage Chicago pension funds have since 2011 poured more than $600,000 in contributions into Mayor Rahm Emanuel's campaign operation and political action committees  that support him, according to documents reviewed by International Business Times. These contributions appear to flout federal rules banning companies that manage pension funds from financing the campaigns of officials with authority over pension systems, say legal experts. The contributions also potentially conflict with an executive order Emanuel himself signed in 2011 prohibiting city contractors and subcontractors from making campaign donations to city officials.
