US Senate Republicans plan to unveil the text of their draft healthcare bill on Thursday as senators struggle over issues such as the future of the Medicaid program for the poor and bringing down insurance costs.
Republicans in the chamber have been working for weeks behind closed doors on legislation aimed at repealing and replacing major portions of the Affordable Care Act, former Democratic President Barack Obama's signature healthcare law, popularly known as Obamacare.
The effort has been plagued from the start by tensions between moderates and conservatives, which surfaced again on Tuesday. Democrats have also criticized the behind-the-scenes meetings, staging a protest on the Senate floor on Monday.
"Republicans are writing their healthcare bill under the cover of darkness because they are ashamed of it," Senate Democratic leader Chuck Schumer charged.
