The House is poised to take up a bill that would gut the Affordable Care Act and make it harder for the president to repeal the law without facing a Senate filibuster.
The measure, which would strip away funding for Planned Parenthood and make a series of other changes to the Affordable Health Care Act, is backed by Republican leaders and is expected to be passed.
The measure has the support of Republicans in the House, but it faces some of the toughest obstacles in the Senate, which is controlled by President Donald Trump.
The Republican leadership will need at least a two-thirds majority to get it through the Senate.
House Speaker Paul Ryan and Senate Majority Leader Mitch McConnell are expected to use the procedural maneuver known as “budget reconciliation” to strip the measure of its funding.
Democrats would have to agree to the bill as well.
The House has passed the measure a second time by a vote of 235-183 in late March.
If it becomes law, the measure would undo some of President Barack Obama’s signature achievements including expanding access to health care and repealing the law’s taxes and regulations.
Republicans are also aiming to weaken the Affordable Child Care Act by making it more difficult for employers to deny coverage to their workers or to exclude them from their health plans.
The bill also eliminates the requirement that people buy insurance on their own.
Democrats have promised to block the bill unless it contains more money for Planned, which they say helps millions of low-income women get health insurance.
The Obama administration says that’s an exaggeration.
