Senate Commerce Committee Chair Jay Rockefeller (D-WV) has introduced a bill to regulate various health insurer underwriting practices. Rockefeller recently stated his belief that insurers find ways to "exploit loopholes" in laws and has promised ongoing oversight by the Commerce Committee of insurance industry practices. Rockefeller is also interested in expanding Medicaid and promoting electronic health record utilization. Rockefeller clearly has a powerful position, but with such statements he is also putting down his marker that Senators Baucus and Kennedy will have to pay attention to his views as they structure health care reform.
