WASHINGTON (Reuters) - Repealing and replacing the U.S. Affordable Care Act in one action would be “ideal,” but it “may take time” to get all elements of the heath care law’s alternative ready, President-elect Donald Trump’s incoming chief of staff said on Sunday.

A full repeal and replacing of Obamacare may not happen immediately but it will happen “as quickly as possible,” Reince Priebus said on the CBS program “Face the Nation.”
