Four centrist Republicans have broken with their party's leadership over health care. They've signed onto a Democratic-led petition that will force a House vote on extending for three years an enhanced pandemic-era subsidy that lowers health insurance costs for millions of Americans.

Johnson faces latest challenge as GOP attempts to move forward with package to lower health care costs but ignores bipartisan calls to extend Obamacare subsidies.

Centrist members had been pressuring leadership for a vote to extend the subsidies, but they were unable to reach a deal.

Mike Johnson avoided commenting on Trump's criticism of Rob Reiner, choosing instead to condemn "senseless violence."
