While taxpayers are flipping the bill to keep America’s auto industry afloat, an undercover investigation shows illegal activities by Chrysler employees who have enjoyed nearly $15 billion in government money.

 Dozens of autoworkers in Detroit were caught on camera drinking beer and smoking marijuana before heading to work at the Chrysler plant that President Obama praised in a speech just two months ago.

  An exclusive investigation by MyFoxDetroit showed workers at Chrysler’s Jefferson North Assembly Plant in Detroit, Mich., drinking beer and smoking joints while on a half-hour lunch break at a nearby park.

  The investigation — conducted over several weeks and based on tips from workers at the plant — outraged the auto giant’s top executives who reportedly called the behavior “totally unacceptable.”
