Frankie Sanders thought he could fool his union. Instead, he made a fool of himself. And now he's facing civil and possibly criminal charges. On February 9, the American Postal Workers Union (APWU) filed suit in federal court against the former Houston-based union official charging that he had defrauded the union of more than $13,000. The APWU alleges Sanders, a business agent and regional coordinator, employed tactics of racketeering, deceit and breach of contract to disguise more than 20 acts of embezzlement for supposed union-related trips. Ed Gallagher, deputy criminal chief for the U.S. Attorney's Office in Houston, has asked the Labor Department and the Postal Service to conduct a criminal probe.
