Feds Investigating Walmart: Report

The Justice Department has been conducting a criminal investigation of Walmart, several sources tell The Washington Post and Bloomberg. The probe started in December after Walmart met voluntarily with Justice officials and told them it was looking into whether its Mexico arm had paid bribes. Still, that's long after the retailer allegedly covered up the bribery, according to The New York Times. The Times says a whistleblower informed Walmart executives in 2005 that Walmart de Mexico paid more than $24 million in bribes, but the company shut down its inquiry and didn't inform law enforcement.
