Connecticut House Majority Leader Christopher G. Donovan has called on Gov. M. Jodi Rell to delay the implementation of her new Charter Oak health plan for uninsured adults. The Rell administration intends to merge Charter Oak with the HUSKY health plan for 320,000 low-income children and adults who are eligible for Medicaid. Child advocates complain that Rell's plan may disrupt coverage for needy children. The advocates are also concerned that covering uninsured adults may be too expensive, weakening HUSKY.
