President Obama will tout a key financial benefit of the Affordable Care Act in a White House speech Thursday, highlighting a provision that requires health insurers to devote at least 80 percent of their spending on medical care and health care quality improvement or give rebates to consumers.

The move, which comes as companies are mailing out cash rebates to 8.5 million U.S. households averaging $100 each, offers a contrast to the barrage of arguments congressional Republicans continue to make against the health-care law, better known as Obamacare. On Wednesday night, House Republicans voted the 38th and 39th time to repeal or change the law.
