After a 26-and-a-half-hour markup, Republicans on Wednesday advanced the health care section of the GOP’s sweeping tax bill that would slash Medicaid spending by hundreds of billions of dollars.

Republican infighting over Medicaid work requirements and raising the state and local taxes cap is threatening to derail the “one big beautiful” reconciliation bill. There are currently enough Republican detractors to sink the bill’s markup in the Budget Committee on Friday.

The bill, which Republicans will be working to pass over the next several weeks, is the centerpiece of Trump's legislative agenda.
