Congress faces a June 1 deadline to pass a $72 billion funding package for immigration enforcement agencies, including Immigration and Customs Enforcement and Border Patrol, before lawmakers leave for a scheduled recess.

Republican leaders are advancing the legislation through a budget reconciliation process, which would allow the package to pass the Senate with a simple majority and bypass the traditional 60-vote threshold required to overcome a filibuster.

However, the effort has encountered resistance from within the GOP caucus. At least one Senate Republican is threatening to oppose the package over disagreements related to funding requests connected to former President Trump's properties.

The internal dispute centers on what sources describe as Trump's "billion-dollar request" for his ballroom, though specific details of this funding provision were not immediately available. The disagreement highlights tensions within the Republican Party as it seeks to advance immigration enforcement priorities.

Both chambers of Congress are working to finalize the legislation before the week's end. The use of reconciliation reflects Republican efforts to advance the package without Democratic support, though the internal GOP divisions could complicate passage in the closely divided Senate.
