President-elect Donald Trump and House Speaker Paul Ryan agree that repealing the Affordable Care Act and replacing it with some other health insurance system is a top priority.
But they disagree on whether overhauling Medicare should be part of that plan. Medicare is the government-run health system for people age 65 and older and the disabled.
Trump said little about Medicare during his campaign, other than to promise that he wouldn't cut it.
Ryan, on the other hand, has Medicare in his sights.
