On Tuesday's broadcast of CNN's "Don Lemon Tonight," economist, Harvard Professor, Director of the National Economic Council under President Barack Obama, and Treasury Secretary under President Bill Clinton Larry Summers said that inflation will not "get that close to the 2% that is the Fed's central objective." And that while it's not for certain, "probably early next year, the most likely thing is that you'll see the economy will be very substantially slow and perhaps you'll see a period of negative growth."
