Lawmakers on Thursday released emails that appeared to show Wal-Mart Chief Executive Mike Duke knew as far back as 2005 of allegations that company representatives had bribed Mexican officials.

The emails appeared to contradict the company’s public statements about a bribery scandal tied to its Mexican affiliate, Wal Mart de Mexico. Lawmakers said Wal-Mart Stores Inc did not dispute the authenticity of the emails.
