Former Gov. Robert L. Ehrlich Jr. led trade missions to Singapore, China and Israel. His lieutenant governor, Michael S. Steele, went to Ghana, South Africa, Paris, Barbados and Israel. Former Gov. Parris N. Glendening took overseas trips with an aide who would later become his wife, and former Gov. William Donald Schaefer traveled to Europe, the Soviet Union, Canada, the Middle East and Asia. All of them raised some eyebrows, but it is Gov. Martin O'Malley's recently concluded trip to China, South Korea and Vietnam that seems to be getting the most scrutiny. Republicans are demanding a detailed accounting of all state money spent on the trip, and the governor has been unusually aggressive in touting the accomplishments of the trade mission with a news release and a press conference upon his return.
