The U.S. House passed a nearly $70 billion immigration enforcement funding package Tuesday on a 214-212 vote, sending three years of funding to federal agencies with no new oversight requirements on how agents operate. The bill now heads to President Trump's desk.

The narrow margin reflected near-unanimous Republican support and unified Democratic opposition. House Majority Leader Steve Scalise of Louisiana shepherded the measure through what had been a contentious final stretch. Democrats argued the package amounted to a blank check for enforcement operations that have already drawn legal challenges in multiple states.

For Montanans, the vote arrives in the middle of an active legal dispute between Attorney General Austin Knudsen and Gallatin County Attorney Audrey Cromwell over whether local prosecutors can be compelled to cooperate with federal immigration agents — a fight that is currently before the Montana Supreme Court. The new federal funding is likely to intensify pressure on counties to take a position.

The legislation covers fiscal years running through the end of the decade and funds operations across U.S. Customs and Border Protection, Immigration and Customs Enforcement, and related agencies. No amendment requiring judicial oversight of detention operations or data collection practices survived the final vote.
