WASHINGTON (AP) — Republican anxiety is mounting over voting to unravel the health care law without having an alternative in hand. That uncertainty is being fanned by words from Donald Trump to a GOP senator.

GOP leaders have made dismantling President Barack Obama's health care overhaul their top 2017 priority. The Republican-run Senate is near passage of a budget that would make it harder for Democrats to protect Obama's law.

At least six GOP senators have expressed qualms about repeal without having a substitute. Republicans have failed for years to produce their own plan.

Kentucky GOP Sen. Rand Paul says the president-elect telephoned him Friday to voice support for doing repeal and replace together.

GOP congressional leaders have discussed a quick repeal, followed by work on an alternative that could take years.
