Joe Biden serves as US Senator

When Biden did take office on January 3, 1973, at age 30 (the minimum age to become a U.S. Senator), he became the sixth-youngest senator in U.S. history.

In 1974, freshman Senator Biden was named one of the 200 Faces for the Future by Time magazine.
Biden was subsequently elected to six additional terms, in the elections of 1978, 1984, 1990, 1996, 2002, and 2008, usually getting about 60 percent of the vote. He did not face strong opposition; Governor Pierre S. du Pont, IV chose not to run against him in 1984. Biden spent 28 years as a junior senator due to the two-year seniority of his Republican colleague William V. Roth, Jr.. After Roth was defeated for re-election by Tom Carper in 2000, Biden became Delaware's senior senator. He then became the longest-serving senator in Delaware history. In May 1999, Biden set the mark for youngest senator to cast 10,000 votes.
In February 1988, after suffering from several episodes of increasingly severe neck pain, Biden was taken by long-distance ambulance to Walter Reed Army Medical Center and given lifesaving surgery to correct an intracranial berry aneurysm that had begun leaking; the situation was serious enough that a priest had administered last rites at the hospital. While recuperating, he suffered a pulmonary embolism, which represented a major complication. Another operation to repair a second aneurysm, which had caused no symptoms but was also at risk from bursting, was performed in May 1988. The hospitalization and recovery kept Biden from his duties in the U.S. Senate for seven months. Biden has had no recurrences or effects from the aneurysms since then.

elected as a Democrat to the United States Senate in 1972 and reelected in 1978, 1984, 1990, 1996, 2002, and again in 2008 and served from January 3, 1973, until January 15, 2009, when he resigned to become Vice President; chair, Committee on the Judiciary (One Hundredth through One Hundred Third Congresses), Committee on Foreign Relations (One Hundred Seventh Congress [January 3-20, 2001; June 6, 2001-January 3, 2003], One Hundred Tenth Congress); was an unsuccessful candidate for Democratic nomination for president in 2008, but was elected Vice President of the United States on the Democratic ticket headed by Barack Obama, and was inaugurated on January 20, 2009.

Biden, senator from Delaware 1973-2009, chaired the Senate Judiciary Committee and subsequently the Committee on Foreign Relations. Biden in 2007 was ranked as the third most liberal Senator by the non-partisan National Journal. He previously ran for President in 1988 but dropped out of the race after admitting he had plagiarized a speech by the leader of the British Labour Party.
