Oklahoma Attorney General Scott Pruitt told the House Committee on Science, Space and Technology’s Environment Subcommittee that he believed in the Environmental Protection Agency’s role in the government and he supports clean air and water. However, he feels the states themselves are supposed to be the primary environmental regulators, not the federal government.
