Congressional leaders are objecting to a decision by the Centers for Medicare & Medicaid Services to reject an Ohio children's health coverage proposal.
Ohio wants to expand its State Children's Health Insurance Program to include more children from moderate-income families.
CMS officials turned down the Ohio application in December 2007, contending that states should use only state funds if they want to use SCHIP to cover children at levels higher than 250% of the federal poverty level, or about $43,000 per year.
Several Democrats have written a letter to Michael Leavitt, secretary of the U.S. Department of Health and Human Services, the parent of the CMS, to attack the decision.
