Two Democratic congressmembers are claiming Wal-Mart CEO Mike Duke was told of bribery allegations surrounding the retail giant’s expansion in Mexico as early as 2005. Emails disclosed by Rep. Henry Waxman of California and Rep. Elijah Cummings of Maryland show Walmart International’s general counsel emailed Duke and other executives about specific bribes for the opening of a number of stores in November 2005, contradicting Wal-Mart claims its top officials were unaware. In a letter to Duke, the congressmembers write: “It would be a serious matter if the CEO of one of our nation’s largest companies failed to address allegations of a bribery scheme.” The Justice Department is currently investigating whether Wal-Mart violated the Foreign Corrupt Practices Act, which makes it a crime for American corporations to bribe foreign officials.
