David Martin is CBS News’ national security correspondent, where he’s covered the Pentagon and the State Department since 1993. He has reported virtually every major defense, intelligence and international affairs story for the “CBS Evening News,” as well as for other broadcasts, including “60 Minutes” and “48 Hours” in that time.

Martin has received several Emmys, most recently in 2012 for his story “Starting Over.” He has also received two Alfred I. duPont-Columbia University Awards (2002 and 2004) for his body of work.

In awarding the second DuPont, the committee said, “David Martin’s reports on the Pentagon, the military build-up to the Iraq war and on the war itself demonstrate his exceptional grasp of national security issues. Teamed with his long-time producer, Mary Walsh, Martin consistently breaks new information with clear reporting on the Pentagon’s goals. He exemplifies the role of a journalist: to measure what we are being told against what we find out.”

Martin also received the 2004 Joan S. Barone Award for excellence in Washington-based national affairs and public policy reporting awarded by the Washington Radio & Television Correspondents’ Association.

He joined CBS News as its Pentagon correspondent in 1983. Martin’s duties later expanded to include the State Department and intelligence beats.

Before that, he covered defense and intelligence matters for Newsweek magazine from its Washington bureau (1977-83). Martin was a reporter with the Associated Press in Washington (1973-77), covering the FBI and CIA. He also was a member of the AP special assignment team (1977).

Martin began his journalism career as a researcher for CBS News in New York in 1969. He then became a news writer with the AP broadcast wire (1971-72) and a fellow at the Washington Journalism Center (1973).

Martin is the author of two books, “Wilderness of Mirrors” (Harper & Row, 1980), an account of the secret wars between the CIA and KGB, and “Best Laid Plans: The Inside Story of America’s War Against Terrorism” (Harper & Row, 1988).

He was born July 28, 1943, in Washington, D.C. He graduated from Yale University in 1965 with a bachelor’s degree in English. During the Vietnam War, Martin served as an officer aboard a U.S. Navy destroyer.
