Anthem, which currently oversees Affordable Care Act plans for about 1.1 million people in 14 states, is one of the largest of the multi-state insurers that hasnt pulled back sharply from selling individual plans in the ACA.

While certain changes helped gain votes in the House, the CBO said the alterations to the AHCA bill would undermine protections for the sick and destabilize insurance markets for about a sixth of the U.S. population.

The insurance industrys main lobby, Americas Health Insurance Plans, criticized the House bill, saying the Senate should boost subsidies to help people afford insurance.

House Speaker Paul Ryan and his GOP lieutenants can afford to lose no more than 21 votes in the chamber, presuming all Democrats vote against the bill.

After the CBO report estimated 24 million Americans would lose insurance, several groups and thought leaders continued to voice their disapproval of the GOP Affordable Care Act replacement proposal.

Although it was expected, the coverage-loss estimate is a sweeping blow to President Trump and fellow Republicans, who are trying to push the legislation through the House and Senate without Democratic support.

Paul Ryan says the 2018 midterm elections will be a 'bloodbath' if Republicans don't deliver on their promise to repeal and replace the Affordable Care Act.

Trump has called the Affordable Care Act a failure, and said hell replace it with a plan providing better, cheaper coverage, without giving details.
