More than 70 preachers and other clergy are leading an effort to find federal aid to save ailing Metro Nashville General Hospital at Meharry if local and state funding is cut. Nashville Mayor Karl Dean has written a letter to the hospital authority, which runs Metro General, saying a better way of funding the facility needs to be found. Dean said the city's financial considerations in the current economic climate will leave it unable to help the hospital make up a projected budget shortfall when the fiscal year ends on June 30.
