House Republicans are preparing to push their hard-fought package of tax breaks and spending cuts through its next hurdle Friday in the Budget Committee, but conservatives are warning they could vote to halt it unless there are further changes.

House Republicans unveiled a plan for Trump’s “big, beautiful bill" on tax breaks earlier this week that also includes massive cuts to Medicaid. Johnson is one of a handful of conservatives against the bill, arguing that it is a “mistake” that will only increase the deficit.

Republicans in Congress have an incredibly slim majority to pass a funding bill for a Trump-led agenda that includes cutting taxes, boosting immigration enforcement, and shrinking other programs.
