According to a new report by the San Jose Mercury News, workers were flown from around the world and paid as little as $5 an hour to build a new paint factory in Fremont for automaker Tesla.

Tesla has responded to the allegations with a statement and then multiple tweets and interviews by its founder, Elon Musk, which have pushed blame to subcontractors.

Louis Hansen wrote the report and he takes time to speak with Josie Huang about his discoveries.
