Richard Blumenthal was born in Brooklyn, N.Y., and now lives in Greenwich, Conn. He earned a bachelor's degree from Harvard University in 1967 and a law degree from Yale University in 1973.
Blumenthal has served as a sergeant in the U.S. Marine Corps Reserve.
He was the U.S. attorney for Connecticut and held seats in the state House of Representatives and the state Senate.
He served as Connecticut's attorney general from 1990 until his election to the U.S. Senate in 2010.
Blumenthal and his wife, Cynthia, have four children.
In Richard Blumenthal's first term in the U.S. Senate, he has focused on issues including the employment of U.S. veterans, immigration reform and a call for a federal approach to fighting Lyme disease.
He defeated Republican Linda McMahon in the 2010 election. His name recognition from more than 35 years of political service in Connecticut helped him win the seat and succeed retiring Democratic Sen. Chris Dodd.
Blumenthal was a popular Democratic attorney general and immediately threw his name into the race when Dodd announced in January 2010 that he was not seeking re-election.
McMahon took credit for helping The New York Times with articles published on how the attorney general misspoke about his military service. Blumenthal had stated that he served "in" Vietnam several times when he actually served stateside in the Marine Corps Reserve.
A Quinnipiac University poll in January 2010 showed Blumenthal with a 41-point lead over McMahon, but survey results released the day before the August primary revealed that lead had shrunk to 10 points.
Blumenthal had been Connecticut attorney general since 1990 and had aggressively focused on issues concerning the environment, consumer protection, labor rights and personal privacy.
Over the course of his five terms as attorney general, his office investigated a wide range of companies, from Microsoft to MySpace. Opponents say this style has in part led to Connecticut developing a reputation as being "anti-business" and has caused lawsuit-weary corporations to steer clear of settling in the state.
Before being elected attorney general, Blumenthal served in the state Senate and was a member of the state House of Representatives prior to that. He is also a former U.S. attorney for Connecticut, where from 1977 to 1981 he prosecuted civil rights violators, polluters, drug traffickers, white-collar criminals and others.
Blumenthal also served as a law clerk to former U.S. Supreme Court Justice Harry Blackmun, an aide to former U.S. senator Daniel Moynihan and an administrative assistant to former U.S. senator Abraham Ribicoff.
Blumenthal says he is in favor of Connecticut promoting technological innovation and entrepreneurship to create more jobs. He also says he is in favor of President George W. Bush's tax cuts for the middle class and believes the 2010 health care reform law is a step in the right direction but would like to see more done to lower the cost of care.
