This bill, called the Sanctuary City Elimination Act, is designed to pressure states and cities that have policies limiting cooperation with federal immigration enforcement. The bill does this primarily through financial punishment—it would cut off federal funding to any jurisdiction deemed a "sanctuary jurisdiction" across multiple grant programs including education, environmental protection, economic development, and community development.

The bill defines a "sanctuary jurisdiction" as any state or local government that has policies preventing it from sharing immigration status information with federal authorities or complying with federal immigration detention requests (called "detainers"). However, there's an exception: jurisdictions can still protect crime victims and witnesses who come forward without losing their sanctuary status.

The bill also grants legal protections to local law enforcement officers who comply with federal immigration detainers, treating them as federal agents and shielding them from lawsuits. Additionally, it allows state attorneys general to sue other states if someone released by a sanctuary jurisdiction commits a crime in their state, seeking to withhold that sanctuary jurisdiction's federal funding. The bill includes a provision stating that nothing in it provides immunity for people who knowingly violate someone's civil or constitutional rights.
