California Gov. Arnold Schwarzenegger reiterated his call for Congress to pass a bill this year to overhaul the U.S. healthcare system, while also expressing concerns about the legislation's potential impact on state budgets. In a letter sent to congressional leaders, the governor, who is one of few prominent Republicans supporting the health effort in Washington, said he opposed proposals to expand Medicaid to provide healthcare coverage to the uninsured. Also in his letter, Schwarzenegger said Congress should fund all of the proposed Medicaid expansion, as well as the healthcare provider rate increases that come along with it, the Wall Street Journal reports.
