WASHINGTON — Protesters pushing for a government-run health system have been thrown out of a Senate hearing room after disrupting the meeting. It happened at the start of a Senate Finance Committee session on overhauling the health care system to cover some 50 million uninsured Americans. Finance Committee Chairman Max Baucus, D-Mont., has said that a so-called single-payer system _ one that's run by the government _ is not on the table.
