A House Republican said Saturday his party would work to repeal President Obama's health care law if the Supreme Court upholds it next week.

"Not only is President Obama's health care law not working, it makes things worse by driving up health care costs, making it harder for small businesses to hire workers," said Rep. Bill Cassidy, R-La., during the Republican weekly radio address.

The Supreme Court is expected to rule next week on the constitutionality of the law that Obama signed in 2010.

Regardless of the ruling, health care figures to play a major role in the fall election between Obama and Republican Mitt Romney, as well as races for control of the U.S. House and Senate.

Cassidy, a doctor, said that if the GOP wins full control of Congress, it should repeal any existing parts of Obama's law, and replace it with a more gradual approach to health care policy.

"It's now clear, if it wasn't already, that containing costs step by step -- not expanding government in one fell swoop -- is the right approach to health care reform," Cassidy said.
