ABCNEWS' John McWethy

— -- John McWethy is ABCNEWS' chief national security correspondent, a position he has held since 1984.

McWethy reports on military and diplomatic aspects of U.S. foreign policy, primarily from the Pentagon in Washington. In addition to his daily coverage for World News Tonight With Peter Jennings, he also files stories for Nightline, Good Morning America and other ABCNEWS broadcasts.

McWethy was at the Pentagon on Sept. 11, 2001, when the building was struck by an American Airlines passenger plane. He was heavily involved in ABCNEWS coverage of the aftermath, which included the U.S. war on terrorism and the war in Afghanistan. McWethy went to Tora Bora in Afghanistan — traveling with U.S. special operations teams there — as the hunt for Osama bin Laden continued.

McWethy's assignments have included coverage of the air war over Kosovo, tensions in the Persian Gulf and in North Korea, and the India-Pakistan conflict. He spent months in Bosnia before and after American troops arrived, and visited Liberia during the worst of the fighting, when the U.S. Embassy was under siege. Assignments have also included reports from Haiti, Somalia, Mozambique, Russia and the Middle East.

For more than a decade, McWethy was ABCNEWS' primary correspondent covering secretaries of state James Baker, George Shultz, Warren Christopher and Lawrence Eagleburger. He has traveled to more than 50 countries, covering the collapse of the Soviet Union and the rise of the new, troubled nations that replaced it.

Though much of McWethy's focus has been on national security and diplomacy, his stories have also touched upon terrorism, espionage and intelligence matters. He was heavily involved in coverage of the Oklahoma City bombing and has twice traveled to Antarctica.

McWethy reported on all five historic meetings between President Ronald Reagan and Soviet leader Mikhail Gorbachev. He covered the Iran-Contra affair and from Washington, the U.S. invasions of Grenada and Panama and Israel's invasion of Lebanon.
