Hundreds of emails and internal documents reviewed by WIRED reveal top lobbyists and representatives of America's agricultural industry led a persistent and often covert campaign to surveil, discredit, and suppress animal rights organizations for nearly a decade, while relying on corporate spies to infiltrate meetings and functionally serve as an informant for the FBI. The documents ... detail a secretive and long-running collaboration between the FBI's Weapons of Mass Destruction Directorate (WMDD)"whose scope today includes Palestinian rights activists and the recent wave of arson targeting Teslas"and the Animal Agriculture Alliance (AAA), a nonprofit trade group representing the interests of US farmers, ranchers, veterinarians, and others across America's food supply chain. The AAA has been supplying federal agents with intelligence on the activities of animal rights groups ... with records of emails and meetings reflecting the industry's broader mission to convince authorities that activists are the preeminent "bioterrorism" threat to the United States. Spies working for the AAA during its collaboration with the FBI went undercover at activism meetings, obtaining photographs, audio recordings, and other strategic material. The records further show that state authorities have cited protests as a reason to conceal information about disease outbreaks at factory farms from the public.
