Former Wal-Mart No. 2 says bogus expenses funded anti-union project: Thomas M. Coughlin, former Wal-Mart vice chairman, recently resigned his board seat after the company said it had discovered a pattern of expense-account abuses and fake invoices used to obtain payments. Coughlin says the money was used for anti-union activities, which if true, could violate the National Labor Relations Act. Wal-Mart said its internal investigation found no evidence to support Coughlin's assertions.
