Sen. Barbara Boxer, D-Calif.

A forceful advocate for families, children, consumers, the environment, and her state of California, Sen. Barbara Boxer was elected to the Senator in 1993 after 10 years in the House of Representatives. A national leader on environmental protection, Boxer is the first woman to chair the Environment and Public Works Committee. She also chairs the panel's Subcommittee on Public Sector Solutions to Global Warming, Oversight, and Children's Health Protection. Boxer authored the amendment to the Safe Drinking Water Act ensuring that drinking water standards are set to protect children and other vulnerable populations. She has been a leader in the fight to remove arsenic from drinking water, block oil drilling in the Alaska National Wildlife Refuge and along California's coast, stop the use of human subjects in pesticide testing, and revitalize the Superfund by making polluters - not taxpayers - pay to clean up the toxic waste they leave behind. In addition to her chairmanship of the Environment and Public Works Committee, the California senator also serves on the Senate Foreign Relations Committee and Commerce Committee, is the Democratic Chief Deputy Whip, and serves on the Democratic Policy Committee's Committee on Oversight and Investigations.
