KLEPT, do you have problems with unexpected holiday guests? [MP]

Melrose Park Police Chief Vito Scavo does. Some federal employees came to his home unannounced looking for free stuff. See Sun-Times (Chris Fusco).

Can somebody explain why the Department of Labor is mentioned like it's leading the investigation?

If the feds are investigating the $42 million overhaul of the watermain project, what angle would involve the Department of Labor?

See this post on the fed's September raid.
