Flashback: How The Chicago Mob Hijacked Chicago's Union Movement

United States Department of Justice. Here's why the Justice Department had to step in:

INTRODUCTION

1 . This action is brought against the Construction & General Laborers' District Council of Chicago and vicinity (hereafter "Chicago Laborers District Council," or the "CLDC") to rid the district council of domination and influence by members and associates of organized crime. The CLDC is a group of 21 local unions affiliated with LIUNA. The Chicago Laborers District Council has been infiltrated by corrupt individuals and organized crime figures who have exploited their control and influence over the district council for personal gain and to the detriment of the CLDC.

2. As a result of the strong, pervasive ties to organized crime, officers and employees of the CLDC and its constituent locals and affiliated funds have been chosen and controlled by various members and associates of organized crime. Consequently, the rights of the members of the union to control the affairs of the union have been systematically abused. Those union members who might have opposed this corrupt state of affairs have been intimidated into silence by economic coercion and by the well-known ties between corrupt union officials and organized crime.

Organized crime, in Chicago, doesn't seem to bother Barack Obama too much.
