House Committee on Energy and Commerce

The Committee on Energy and Commerce, the oldest standing legislative committee in the U.S. House of Representatives, is vested with the broadest jurisdiction of any congressional authorizing committee. It has responsibility for the nation’s telecommunications, consumer protection, food and drug safety, public health research, environmental quality, energy policy, and interstate and foreign commerce. It oversees multiple cabinet-level Departments and independent agencies, including the Departments of Energy, Health and Human Services, Commerce, and Transportation, as well as the Environmental Protection Agency, the Federal Trade Commission, the Food and Drug Administration, and the Federal Communications Commission.
