The GOP debate Wednesday night started with a bang over the topic of immigration. Presidential hopefuls Rudolph Giuliani and Mitt Romney traded barbs over their past policies on immigration, at which point Giuliani accused Romney of employing illegal immigrants to do landscaping at his home. It's a story that The Boston Globe reported on last year.
Romney shot back, asking whether it's the responsibility of homeowners to determine the status of people working with a contractor. And that's a question that many middle-class Americans have had occasion to ponder.
Susan Gzesh, director of the University of Chicago's Human Rights Program, talks with Robert Siegel about what homeowners are obliged to do.
