The Republican-controlled House of Representatives will delay its vote on repealing and replacing parts of the Affordable Care Act after GOP leadership struggled to rally the support to pass the bill, sources told CNBC.

House Republicans will meet at 7 p.m. ET to talk about their path forward, NBC News reported. A vote on the legislation is still possible on Friday, NBC said.

The White House gave the House Freedom Caucus a final offer Thursday in its effort to win enough votes for the legislation. The conservative group’s leader said Thursday afternoon that no deal was reached.

Earlier Thursday, the White House insisted the bill would still clear the House.

“It’s going to pass. So that’s it,” Spicer told reporters when asked what would happen if the bill did not pass.

Trump and Republican leaders have made health care their top legislative priority since Trump took office with a GOP congressional majority in January. While they ran on repealing Obamacare, Republicans walk a political tightrope, as most independent estimates have shown the current GOP plan will lead to more people uninsured.

Trump has said the repeal and replacement of Obamacare must happen before action can be taken on his other plans, including a major tax reduction. Republicans need 215 votes for passage.

Some public opinion polls have also shown that voters strongly oppose the proposal in its current form.
