President Trump and Republican senators are locked in a funding dispute over a $1.8 billion anti-weaponization program, threatening the administration's push for immigration enforcement legislation. The disagreement centers on the fund's legality and lack of oversight, with Senate Majority Leader John Thune sending senators home for Memorial Day recess, delaying action.

The Republican split breaks with the White House and jeopardizes Trump's June 1 deadline to have ICE and Border Patrol funding on his desk. The immigration-enforcement bill became a negotiating tool, as GOP lawmakers leverage their position to pressure the administration on the compensation program. The delay pushes Congress further from meeting the self-imposed timeline for securing border security funding.

This funding dispute reveals deeper tensions within Republican ranks over spending priorities and government oversight. The delay affects both domestic security policy and the administration's broader legislative agenda, with implications for how Congress tackles border funding and program accountability moving forward.
