The State AG's and Walmart.

Connecticut AG Dick Blumenthal slammed Wal Mart last week for labor violations, asking other states to join Connecticut in investigating allegations the world's largest retailer broke child labor laws.
Columbia 2L - Peter Romer-Friendman - has written an article on the role of AG's in enforcing
wage and hour laws. That paper can be found at http://www.stateag.org which is part of the AG Library, a CLS entity. The AG Library has a great newsletter for folks interested in the role of the State AGs in multi-state litigation.
