US SB3921

Sanctuary jurisdictions become ineligible for federal Special Event Assessment Rating (SEAR) support funds, including DHS risk assessments, explosive detection teams, and cyber support for major events, after receiving 30-day notice and failing to certify compliance with federal immigration laws

"Sanctuary jurisdiction" is defined as any state or locality that restricts sharing immigration status information with federal entities or refuses to comply with DHS detainer requests under sections 236 or 287 of the Immigration and Nationality Act

Funds withheld from sanctuary jurisdictions would be reallocated to ICE Enforcement and Removal Operations, with priority given to public safety threats including criminal noncitizens, gang members, and terrorist watchlist individuals, and at least 50% directed to border-related enforcement

The Secretary of Homeland Security must submit semiannual reports to Congress detailing withheld funds, reallocated amounts, enforcement outcomes (arrests, detentions, deportations), and impacts on reducing risks at major events

Congressional findings cite more than 382 border encounters with terrorist watchlist individuals between fiscal years 2021-2024 as justification for linking SEAR support to immigration enforcement cooperation
