House Republicans Push Forward Plan to Cut Taxes, Medicaid and Food Stamps

House Republicans on Wednesday pushed forward with major legislation to deliver President Trump’s domestic agenda, moving over the opposition of Democrats to advance cuts to taxes, Medicaid and food assistance after slogging through all-night and all-day drafting sessions.

The votes, in three key committees, were a crucial step for what Mr. Trump has labeled the “big beautiful bill” that Republicans hope to push through the House by the end of next week. The approvals sent the main pieces of the legislation to the full House, where G.O.P. leaders were racing to pass it before a Memorial Day recess.

The measure would extend Mr. Trump’s 2017 tax cut and temporarily enact his campaign pledges not to tax tips or overtime pay. Cuts to Medicaid, food stamps and subsidies for clean energy would partly offset the roughly $3.8 trillion cost of those tax measures, as well as increased spending on the military and immigration enforcement.

“The American people are counting on us to get this done and get it done quickly, and we are on target to do it,” Speaker Mike Johnson, Republican of Louisiana, said on Wednesday morning at a news conference at the Capitol.

Even as the committees approved their slices of the plan in party-line votes, House Republican leaders faced dissent in their ranks that could delay or derail passage. Conservative lawmakers have argued the proposed cuts to Medicaid, which stopped short of an overhaul in an effort to protect vulnerable Republicans, do not go far enough.

And Republicans from high-tax states like New York were furious about a provision that would increase the limit on the state and local tax deduction to $30,000 from $10,000, a cap they regard as far too low and which was still being negotiated.
