A long-sought bipartisan deal to extend the Affordable Care Act's enhanced premium tax credits for two years has stalled, according to Republican senators, with the Hyde amendment's abortion-funding language a sticking point as the enrollment deadline arrives for the more than 20 million Americans who rely on the subsidies. Sen. Bernie Moreno says the talks are "in a little bit of a pothole" and blames Democratic leaders, while Sen. Lisa Murkowski says Republicans are hung up on Hyde language and will need White House buy-in; Democratic leaders have not endorsed the Senate plan.
