Overview
- Independent journalist Ken Klippenstein reports, citing an unnamed CBP/Border Patrol source, that federal agencies maintain more than a dozen secret watchlists monitoring Americans, a claim not independently verified.
- The lists allegedly prioritize tracking so-called aggressive protesters, with particular attention to anti-ICE and pro-Palestinian demonstrators, alongside immigrant screening.
- Reported codenames include Bluekey, Grapevine, Hummingbird, Reaper, Sandcastle, Sienna, Slipstream, and Sparta.
- Hummingbird is described as vetting and tracking Afghans seeking U.S. resettlement, while Slipstream is characterized as a classified social media repository.
- Frontline agents reportedly enter data into proprietary apps without visibility into downstream use, and sources say software such as Palantir could aggregate these datasets, though no single unified system is confirmed.
