(WASHINGTON) -- Nine high-ranking U.S. Navy officers, including one former admiral, have been charged with trading classified information in exchange for travel, dinner and prostitution services from a foreign defense contractor -- the latest charges in the widening probe, according to the Justice Department. According to the Justice Department, the Navy officials allegedly took in expensive travel and entertainment expenses as well as prostitution services while steering contracts toward the company, Glenn Defense Marine Asia (GDMA), and blocking its competitors. They allegedly used fake names and foreign email address to keep their actions secret.
