The US Postal Inspection Service (USP IS) ran a secret programme tracking social media users, including racial justice protestors, prompting concerns about its legality.

USP IS' Internet Covert Operations Program (iCOP) used social media monitoring software to identity and track investigation targets, and shared that data with law enforcement agencies, according to Yahoo!. The programme was carried out by the law enforcement arm of the USPS.

The report alleged that iCOP analysts began monitoring social media to track potential violence at racial justice protests following the death of George Floyd, and that the programme enabled USP IS staff to assume fake identities online and employ facial recognition software, including Clearview AI's facial recognition system.

The incident raised questions about the ethics and legality of USPS' targeting and collecting information on US citizens not suspected of any crime and with no connection to the post office.
