    Letter to all recipients of U.S. Department of Transportation funding

    In an April 2025 letter, the U.S. Secretary of Transportation reminded all DOT funding recipients — including state and local governments — that they must comply with federal anti-discrimination laws, including prohibitions on race- and sex-based preferences, and must cooperate with federal immigration enforcement. The letter warns that programs or policies tied to 'diversity, equity, and inclusion' goals may violate federal law, and that issuing driver's licenses to undocumented individuals or otherwise impeding ICE could constitute noncompliance. Recipients who fail to meet these obligations risk losing federal transportation funding, facing audits, or having grant agreements terminated.
