Immigration and Customs Enforcement has signed a $30 million deal with the controversial surveillance tech giant Palantir, which will be used to help track and deport immigrants, including people who might have overstayed their visas. A database would also track cases of self-deportation and share data with Customs and Border Protection. The outlet 404 Media reports Palantir — which was founded by Elon Musk ally, billionaire Peter Thiel — has been working in recent weeks to increase ICE’s capacity to monitor immigrants with final deportation orders. The new agreement is an extension of a contract with Palantir first signed by the Biden administration.
