Republicans will work on unraveling and replacing the health care law at the same time, House Speaker Paul Ryan said Tuesday as GOP leaders struggled to align their zeal to rapidly erase one of President Barack Obama's proudest achievements with Congress' legislative and political pitfalls.

Republican senator who challenged Donald Trump for the White House nomination says the president-elect "fully supports" repealing President Barack Obama's health law only when there's a viable alternative to replace it.

Top Republicans said Sunday they’ll move quickly to enact a new health care law, but they won’t say how long that might take or what might replace President Barack Obama’s version.

Congress opened for battle over the Affordable Care Act on Wednesday as Republicans pushed immediately forward to repeal the health care law and President Obama made a rare trip to Capitol Hill to defend it.

Vice President-elect Mike Pence and the top Republicans in Congress made clear on Wednesday, more powerfully and explicitly than ever, that they are dead serious about repealing the Affordable Care Act.

Republicans are united on repealing President Barack Obama's health care law, but ideologically and practically speaking, they're in different camps over replacing it. Getting the factions together won't be easy.
