Combating Cartels on Social Media Act of 2025

Requires the Secretary of Homeland Security, the Attorney General, and the Secretary of State to produce a joint assessment (within 180 days) of how transnational criminal organizations use social media and related online services for recruitment and illicit activity, and to deliver a joint strategy (within one year) to stop U.S.-based recruitment through those services. The law defines covered services and illicit activities, mandates broad interagency and external consultation, requires civil-rights and privacy assessments and rulemaking before implementation, clarifies it does not expand agency authorities, and forbids any new appropriations to carry out the Act.
