A state audit found that a Southern California school district issued California high school diplomas to students in China who never set foot in the state and never attended a single class here. The scheme ran for years before it surfaced. How does something like that go undetected? In this episode, Sonja Shaw, President of the Chino Valley Unified School Board, walks us through what the audit uncovered and what an ongoing investigation still needs to answer. Joshua Philipp, host of Crossroads, explains how this case connects to larger concerns about foreign influence in American schools.
