President Barack Obama, putting a significant chunk of his political capital on the line, will take his case for change to the airwaves while congressional negotiators tackle politically explosive proposals relating to coverage and cost control.
Overhauling the health care system is Obama's top domestic priority, but the initial proposals to reach Congress last week received a rocky reception. House and Senate Democrats are responding by intensifying their efforts.
They are holding four separate hearings Wednesday focusing, among other things, on the question of how to pay a price tag that may exceed $1 trillion.
