In a major setback for Mike Johnson and the House GOP, four Republicans have joined with the Democrats to sign a petition forcing a vote on legislation that will extend for three years premium tax credits for Affordable Care Act healthcare plans.

The rebellion underscores the nervousness among Republicans over an increase in healthcare costs before the 2026 midterm elections, in which the party will be defending its slim control of the House.
