House Speaker Nancy Pelosi stepped up her push for a publicly run health plan, saying it could "save enormous amounts of money." Congressional aides said including a government-run plan for people under 65 in the health overhaul could save as much as $100 billion, if such a plan were to pay healthcare providers the low rates used by Medicare. The resulting savings would allow Democrats to keep subsidies and other provisions intended to help lower-income people buy health insurance.
