Making a last-ditch effort to save his health care overhaul, President Barack Obama on Monday put forward a nearly $1 trillion, 10-year compromise that would allow the government to deny or roll back egregious insurance premium increases that infuriated consumers. Posted Monday morning on the White House Web site, the plan would provide coverage to more than 31 million Americans now uninsured without adding to the federal deficit. It comes just four days before Obama's one-of-a-kind, televised health care summit with Democrats and Republicans.
