As Judy Muller reports this week, Walmart, already the largest retailer in the world, is looking to expand. Part of its expansion plan involves opening new stores in California, though it faces tough opposition, especially in Los Angeles County.

In this quick behind-the-scenes interview, Muller shares a few extra details that didn't make it into the piece, including a University of California study that suggests a small increase in the superstore's minimum wage for employees would go a long way toward helping people who are living below the federal poverty line.
