Republicans Expected to Unveil Health Care Bill This WeekRepublican U.S. lawmakers expect to unveil this week the text of long-awaited legislation to repeal and replace the Obamacare health care law, one of President Donald Trump's top legislative priorities, a senior Republican congressional aide said on Sunday. Since taking office in January, Trump has pressed his fellow Republicans who control Congress to act quickly to dismantle former Democratic President Barack Obama's Affordable Care Act and pass a plan to replace it, but lawmakers in the party have differed on the specifics. Democrats have warned that Republicans risk throwing the entire U.S. health care system into chaos by repealing the 2010 law that was passed by congressional Democrats over united Republican opposition. Republicans condemn it as a government overreach, and Trump has called it a "disaster." The aide cited progress in meetings and phone calls starting on Friday and lasting through the weekend involving House of Representatives Speaker Paul Ryan, Health and Human Services Secretary Tom Price, White House budget chief Mick Mulvaney, Trump domestic policy adviser Andrew Bremberg and others. "We are in a very good place right now, and while drafting continues, we anticipate the release of final bill text early this week," said the aide, speaking on condition of anonymity. The aide called the expected bill a "consensus Republican plan," but offered no details. AshLee Strong, a spokeswoman for Ryan, said: "We are now at the culmination of a years-long process to keep our promise to the American people." The Obamacare law has proven popular in many states, even some controlled by Republicans, and it enabled about 20 million previously uninsured people to get medical insurance, although premium increases angered some.
