Jeff Stein is an investigative reporter of long standing in Washington, D.C., contributing articles on U.S. intelligence, defense and foreign policy topics for a wide variety of newspapers and magazines. An Army Intelligence case officer in Vietnam during 1968-69, Stein has authored three books: THE VIETNAM FACT BOOK: 1000 QUESTIONS AND ANSWERS ON THE VIETNAM WAR (Dell,1987); A MURDER IN WARTIME: THE UNTOLD SPY STORY THAT CHANGED THE COURSE OF THE VIETNAM WAR (St. Martin's Press, 1992); and (with Khidhir Hamza) SADDAM'S BOMBMAKER (Scribner 2000). In 2002, Congressional Quarterly recruited Stein to launch and edit the daily CQ/Homeland Security online publication. In 2005 he became CQ National Security Editor and launched a weekly column, SpyTalk , which gained a measure of fame when top U.S. counterterrorism officials and members of the House Intelligence Committee couldn't answer his basic question, "Can you tell a Sunni from a Shiite?" An occasional contributor to the New York Times and Washington Post, Stein was deputy foreign editor for UPI during the 1980s. He appears frequently on CBS, CNN, MSNBC, Fox, the BBC and NPR as a commentator on national security issues.
