John Forbes Kerry (born December 11, 1943) is an American attorney, politician, diplomat, and former naval officer who served as the 68th United States secretary of state from 2013 to 2017 in the administration of President Barack Obama. A member of the Democratic Party, he previously represented Massachusetts in the United States Senate from 1985 to 2013 and later served as the first U.S. special presidential envoy for climate from 2021 to 2024. Kerry was the Democratic nominee for president of the United States in the 2004 election, losing to then-incumbent president George W. Bush.
Born into the prominent Forbes family in Aurora, Colorado, Kerry grew up in Massachusetts and Washington, D.C. In 1966, after graduating from Yale University, he enlisted in the United States Naval Reserve, ultimately attaining the rank of lieutenant. During the Vietnam War, Kerry served a brief tour in South Vietnam. While commanding a Swift Boat, he sustained three wounds in combat with the Viet Cong, for which he earned three Purple Heart medals. Kerry was also awarded the Silver Star Medal and the Bronze Star Medal for conduct in separate military engagements. After completing his active military service, Kerry returned to the United States and became an outspoken opponent of the Vietnam War. He gained national recognition as an anti-war activist, serving as a spokesperson for the Vietnam Veterans Against the War organization. Kerry testified in the Fulbright Hearings before the Senate Committee on Foreign Relations, where he described the United States government's policy in Vietnam as the cause of war crimes.
