Wal-Mart spokesman resigns after resume discovery

David Tovar, Wal-Mart Stores Inc.'s vice president of corporate communications, is leaving the retail giant after a background check revealed he hadn't finished his college degree.

The error was discovered during an assessment of the process of his promotion to senior vice president, Tovar told CNBC.

"As part of that process, I was going through additional leadership assessment, including a battery of tests including questions about leadership, drug tests, background checks," he said. "In the background check, my education was flagged - it was done by a third party company. They asked me about it, and I was 100 percent transparent."

While he walked in the University of Delaware's graduation ceremony, he later learned he was a few credits short.

"I got a job and never looked back. I really didn't think an art degree would matter in communications, which was the field I went into," he said.
