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 and only U.S. special presidential envoy for climate from 2021 to 2024. Kerry was the Democratic presidential nominee in the 2004 presidential election. 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. In 1972, Kerry was an unsuccessful candidate for the U.S. House of Representatives in Massachusetts's 5th congressional district, losing to Republican Paul W. Cronin in the general election. He subsequently worked as a radio talk show host, as the executive director of an advocacy organization while attending law school, and later in private legal practice. In 1982, Kerry was elected lieutenant governor of Massachusetts as the running mate of Michael Dukakis's ticket. In 1984, Kerry was elected to the United States Senate representing Massachusetts. During his career in the Senate, Kerry won the Democratic nomination in the 2004 Democratic Party presidential primaries, but lost the general election to incumbent Republican president George W. Bush. In January 2013, Kerry was nominated by President Obama and confirmed by the Senate to succeed Hillary Clinton as Secretary of State, serving through the rest of Obama's second term. During his tenure, he initiated the 2013–2014 Israeli–Palestinian peace talks and negotiated agreements restricting the nuclear program of Iran, including the 2013 Joint Plan of Action and the 2015 Joint Comprehensive Plan of Action. In 2015, Kerry signed the Paris Agreement on climate change on behalf of the United States. In January 2021, Kerry returned to government, serving as the U.S. special presidential envoy for climate under President Joe Biden. In March 2024, Kerry left this position to work on Biden's 2024 presidential campaign. Kerry was awarded the Presidential Medal of Freedom by Biden in May 2024.
