David Tovar, Wal-Mart's vice president of corporate communications, is leaving the retail giant after a background check revealed he hadn't finished his college degree.
In a phone interview, Tovar told CNBC the résumé error was discovered while he was undergoing an assessment as part of the process of being promoted to senior vice president. He had been with the retail giant for eight years after working at Altria earlier.
"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."
