The Biden administration is not conducting federally mandated DNA tests on detained illegal aliens, according to new data obtained by Sen. Chuck Grassley (R., Iowa) and shared with the Washington Free Beacon. The data show that Customs and Border Protection only collected DNA samples from 30 to 40 percent of the approximately 3.2 million illegal aliens who entered the United States in fiscal year 2023. The Biden administration’s failure to comply with DNA gathering requirements set out in the 2005 DNA Fingerprint Act comes as the country grapples with a record surge of illegal migrants, many of whom commit high-profile crimes upon entering the country.
