Henry Waxman is the U.S. Representative for California's 33rd congressional district, serving in Congress since 1975. He is a member of the Democratic Party. He is considered to be one of the most influential liberal members of Congress.

A leader on health and environmental issues, Rep. Waxman has fought for universal health care, tobacco regulations, air and water quality standards, and reducing greenhouse gas emissions.

For over 20 years Rep. Waxman has served on the House Energy and Commerce Committee. Most recently, he became the Ranking Member of the committee.

A longtime champion of environmental and public health protection, Rep. Waxman introduced the first bill in Congress to stabilize the climate in 1992. Since then, he has continued his work to advance legislation to avoid dangerous, irreversible global warming, most recently with the passage by the House of Representatives of the American Clean Energy and Security Act of 2009 (also known as Waxman-Markey). 

Rep. Waxman was one of the primary authors of the 1990 Clean Air Act amendments, which comprehensively addressed the problems of urban smog, toxic air pollution, acid rain, and the depletion of the stratospheric ozone layer. Rep. Waxman also sponsored the 1986 and 1996 Safe Drinking Water Act Amendments, the 1996 Food Quality Act (which regulates pesticides), the Radon Abatement Act, and the Lead Contamination Control Act. 

From 2001 to 2008, Rep. Waxman worked to oppose efforts by the Bush administration to block congressional oversight and roll back health and environmental laws. During this time he launched several investigations into questionable White House activity.
