Michael Millikin, the GM chief counsel many see as being the person behind the mishandling of the automaker's ignition switch fiasco, is retiring early. The company has been hit with a $10 billion class action lawsuit alleging it long concealed a series of safety problems. While GM CEO Mary Barra issued a statement praising the 66-year-old attorney for his “tremendous career,” it is likely that Millikin’s departure comes as something of a relief. People like Sen. Claire McCaskill, a Maryland Democrat, directly accused Millikin of “incompetence.”
