It still requires congress to change the law
And just a few days ago:
"Congress has set the stage for repeal of the Affordable Care Act, approving a preliminary measure that will allow
Republicans to dismantle Barack Obama’s signature healthcare law.
The legislation passed in the House of Representatives 227-198, with nine Republicans joining a united Democratic party in voting against. The narrowly
Senate passed the same budget measure in the early hours of Thursday morning.
“This is a critical first step toward delivering relief to Americans who are struggling under this law,” said the House speaker, Paul Ryan of Wisconsin, in a rare floor speech.
The move allows Republicans to use a procedure known as “budget reconciliation” to tear up key provisions of the law. Republican leaders have said they intend to “repeal” and “replace” Obamacare simultaneously to avoid disruptions in healthcare coverage, but they have yet to agree on a replacement plan"

But hey, there is absolutely no way that we could have any idea what Trump and the Republican congress might do because none of them have any history that we can look at. Right?
