It will at least force the House to vote on the matter before open enrolment ends on January 15.
Pennsylvania Republican Brian Fitzpatrick was the first Republican to cross party lines and sign a discharge petition to force a vote on a three-year extension of the premium tax credits, untethered to any policy overhauls.
He was swiftly joined by others including Lawler, one of the most vulnerable Republicans in the 2026 Midterm race.
Also signing were Pennsylvania’s Robert Bresnahan and Ryan Mackenzie.
That pushed the petition to 218 votes, a majority of the House, which now forces House leaders to bring the subsidies bill to the floor after a seven-day waiting period.
The House is set to recess for Christmas this weekend.
The political uncertainty surrounding the future of the subsidies complicates matters for Obamacare policyholders, who will on average see their premium more than double without the tax credit, according to KFF, a nonpartisan health research institute.
The deadline to secure coverage for the month of January was Monday local time.
In most cases, Americans will lose the chance to obtain Obamacare insurance next year unless they commit before January 15, and it’s unclear whether the Senate would quickly follow the House on acting next month.
The Senate had already rejected the three-year subsidy extension in a test vote this month.
If the House passes the extension next year, it could allow the Senate to amend the bill to make it more palatable to enough Republicans to pass in that chamber.
A bipartisan group of senators convened this week to explore what such a compromise could look like, including income limits for recipients of the tax credit and anti-fraud measures.
The moderates’ revolt is the latest sign that Johnson is losing his grip on control of the House.
A similar discharge petition was used to force passage of a Bill over Johnson’s objection compelling the Trump Administration to release files related to the crimes of disgraced financier Jeffrey Epstein and passage of a Bill to protect federal workers’ union rights.
Johnson enjoys a slim majority with just 220 seats and a tough fight to retain control of the chamber in next year’s election with US President Donald Trump’s declining unpopularity.
Democrats plan to make the Obamacare subsidies the centrepiece of their campaign, focusing on the districts of the moderates now pushing back against Johnson.
