No DOT Funds for Sanctuary Cities Act

This bill prohibits the Department of Transportation from providing any federal grants or funds to local governments (including cities, counties, or other state subdivisions) that are classified as "sanctuary cities." A sanctuary city is defined as any local government that restricts sharing immigration status information with federal authorities or refuses to comply with certain immigration detainer requests from Homeland Security. The Secretary of Transportation may grant a limited waiver for specific projects if they certify it serves national interest and notify Congress 15 days in advance. The law directly affects jurisdictions with policies limiting cooperation on immigration enforcement, withholding all DOT funding for transportation projects.
