Joseph Robinette Biden Jr. born on November 20, 1942, is an American politician who served as the 47th vice president of the United States from 2009 to 2017.

Biden was raised in Scranton, Pennsylvania. He studied at the University of Delaware before receiving his law degree from Syracuse University. He became a lawyer in 1969 and was elected to the New Castle County Council in 1970. He was elected to the U.S. Senate from Delaware in 1972, becoming the sixth youngest senator in American history.

He opposed the Gulf War in 1991 but supported the expansion of the NATO alliance into Eastern Europe and its intervention in the Yugoslav Wars of the 1990s. He supported the resolution authorizing the Iraq War in 2002 but opposed the surge of U.S. troops in 2007. He also served as chairman of the Senate Judiciary Committee from 1987 to 1995, dealing with issues related to drug policy, crime prevention, and civil liberties. Biden led the efforts to pass the Violent Crime Control and Law Enforcement Act and the Violence Against Women Act and oversaw the contentious U.S. Supreme Court nominations of Robert Bork and Clarence Thomas.

In foreign policy, Biden led the efforts to pass the United States–Russia New START treaty, supported military intervention in Libya, and helped formulate U.S. policy toward Iraq through the withdrawal of U.S. troops in 2011. Following the Sandy Hook Elementary School shooting, Biden led the Gun Violence Task Force, created to address the causes of gun violence in the United States.

In October 2015, Biden announced that he would not seek the presidency in the 2016 election. In January 2017, Obama awarded Biden the Presidential Medal of Freedom with distinction. Biden announced his 2020 candidacy for president on April 25, 2019, and in June 2020, he met the 1,991-delegate threshold needed to secure the Democratic Party's nomination On August 11, 2020, Biden announced U.S. Senator Kamala Harris as his running mate in the 2020 presidential election.

Joe Biden would be the oldest president in history at his inauguration, at age 78. Mr. Trump, who is currently 74, would also be the oldest president ever if he wins a second term.
