WASHINGTON (AP) - The new Republican-led House is expected to vote to repeal President Barack Obama's health care law today. Republican Congresswoman Nan Hayworth of New York says the vote "respects the will of the American people" and isn't just symbolic.

The House vote could turn out to be the high-water mark for repeal, a goal that energized conservative voters in the midterm elections and helped Republicans return to power in Congress. Democrats, who hung on to the Senate, have vowed to block the GOP drive.

But House Republicans warn not to underestimate their determination or their willingness to use parliamentary maneuvers to deny the Obama administration funds needed to carry out the law.
