The Department of Homeland Security has drastically ramped up efforts to add DNA from nearly one million immigrants to a massive criminal database. Most of them have no criminal history; some of them are kids. In 2025, Immigration and Customs Enforcement added up to roughly 920,000 DNA profiles into the FBI’s Combined DNA Index System, a database used for conducting criminal investigations, WIRED reported Monday. That’s equivalent to more than 2,700 new profiles every day for an entire year. We know that most of the people added to the database have no criminal record because most of the people who have been detained by ICE as part of President Donald Trump’s massive deportation crusade have no criminal record. New research from Georgetown Law’s Center on Privacy and Technology, published in a report titled “Raiding the Genome: How the United States Government Is Abusing Its Immigration Powers to Amass DNA for Future Policing” uncovered a huge increase in the rate of DNA collection from undocumented immigrants. Customs and Border Protection has historically been responsible for collecting DNA from immigrants entering through the U.S.-Mexico border. Between October 2020 and December 2024, CBP collected the DNA of at least 1.36 million people, more than one dozen times the rate of ICE’s DNA collection during the same period. Even so, CBP’s prior collection rate has been dwarfed by the new data provided by ICE. Among the scores of immigrants whose genomes are now being tracked by the government are the children held at the family detention center in Dilley, Texas, the source of multiple reports documenting unsafe living conditions. “None of the families at Dilley have been convicted of a crime,” Representatives Joaquin Castro, Greg Stanton, and Nanette Barragán said in a joint statement to WIRED. “They do not belong in a database meant for violent criminals, especially children.”The ICE facility in Dilley has been the source of horrific reports about living conditions. Records released to Georgetown by CBP identified 492 children under age 14 whose DNA was sent to the FBI in 2025—including 33 seven-year-olds, 32 six-year-olds, and 21 five-year-olds, WIRED reported. And breaking with past precedent, ICE has also begun charging immigrants who refuse to submit a DNA sample when they are taken into custody. WIRED identified two prosecutions filed in 2025 against people in immigration custody who’d refused DNA collection. In response to questions from WIRED, a DHS spokesperson defended DNA collection and claimed the agency had collected DNA from children in order to verify family relationships. That program is distinct, however, from the DNA collection program centered in WIRED’s reporting.
