Ryan: Obamacare repeal is first priority under Trump

"Well, the first bill we're going to be working on is our Obamacare legislation," he said in an interview airing Sunday night, though he declined to offer a timetable. 

"We want to make sure that we have a good transition period, so that people can get better coverage at a better price."

When pressed by anchor Scott Pelley, who asked about a three-year transition, Ryan said, "I don't know the answer to that right now. What we know is we have to make good on this promise. We have to bring relief as fast as possible to people who are struggling under Obamacare."

In its place, he told "60 Minutes," Republicans will pass a "patient-centered healthcare" that gives people access to "affordable healthcare coverage."

But the Wisconsin Republican, echoing the president-elect, said some of the healthcare law's most popular provisions will remain intact. 

He favors maintaining provisions of Obamacare that allow children to stay on their parents' healthcare plans until the age of 26 and preventing health insurance companies from denying care to those with preexisting conditions.
