Experts dispute some points in health talk

President Obama provided intricate details of health policy at his news conference, but experts said some of his points were debatable. Obama said doctors, nurses, hospitals, drug companies, and AARP had supported efforts to overhaul healthcare, for example. But while it is true the American Medical Association has endorsed a bill drafted by House Democratic leaders, a half-dozen state medical societies have sharply criticized provisions that would establish a new government-run health insurance plan.
