Albert Arnold Gore Jr. (born March 31, 1948) is an American former politician, businessman, and environmentalist who served as the 45th vice president of the United States from 1993 to 2001 under President Bill Clinton. A member of the Democratic Party, he previously represented Tennessee in both houses of the U.S. Congress, first as a member of the U.S. House of Representatives from 1977 to 1985, and then as a U.S. senator from 1985 to 1993. Gore was the Democratic nominee in the 2000 presidential election, losing to Republican nominee George W. Bush. The son of politician Albert Gore Sr., Gore was raised in Tennessee and Washington, D.C., where he was born. After graduating from Harvard University and serving in the U.S. Army, he quit law school to run as a representative for Tennessee's 4th congressional district in 1976. Gore was re-elected three times before running for U.S. Senate in 1984, winning re-election in 1990. He was considered a moderate and an "Atari Democrat". Gore served as vice president during the Clinton administration from 1993 to 2001, defeating then-incumbents George H. W. Bush and Dan Quayle in 1992, and Bob Dole and Jack Kemp in 1996, and was the first Democrat to serve two full terms as vice president since John Nance Garner. As of 2025, Gore's 1990 re-election remains the last time Democrats won a Senate election in Tennessee. Gore was the Democratic presidential nominee in the 2000 election, in which he lost the U.S. Electoral College vote by five electoral votes to Republican nominee George W. Bush while winning the popular vote by 543,895 votes. The election concluded after the U.S. Supreme Court ruled 5–4 in Bush v. Gore against a previous ruling by the Supreme Court of Florida on a re-count. He is one of five presidential candidates in American history to lose a presidential election despite winning the popular vote. After his vice presidency ended in 2001, Gore remained prominent as an author and environmental activist, and his work in climate change activism earned him (jointly with the IPCC) the Nobel Peace Prize in 2007. Gore is the founder and chair of The Climate Reality Project, the co-founder and chair of Generation Investment Management, the since-defunct Current TV network, a former member of the Board of Directors of Apple Inc. and a senior adviser to Google. Gore is also a partner in the venture capital firm Kleiner Perkins, heading its climate change solutions group. He has served as a visiting professor at Middle Tennessee State University, Columbia University Graduate School of Journalism, Fisk University, and the University of California, Los Angeles. He served on the Board of Directors of World Resources Institute. Gore has received a number of awards that include the Nobel Peace Prize (joint award with the Intergovernmental Panel on Climate Change, 2007), a Primetime Emmy Award for Current TV (2007), and a Webby Award (2005). Gore was also the subject of the Academy Award winning (2007) documentary An Inconvenient Truth in 2006, as well as its 2017 sequel An Inconvenient Sequel: Truth to Power. In 2007, he was named a runner-up for Time's 2007 Person of the Year. In 2008, Gore won the Dan David Prize for Social Responsibility, and in 2024 was awarded the Presidential Medal of Freedom by President Joe Biden.
