NASHVILLE, Tenn. (AP) — Another effort to expand the Tennessee's Medicaid program has failed after the state's Republican-dominated House refused to support an amendment on a bill on insurance coverage for certain cancer patients. The failed amendment was brought by House Minority Leader Craig Fitzhugh, a Democrat from Ripley who is running for governor. The amendment would have allowed the governor to expand TennCare, the state's Medicaid program.
