Is the US government purchasing cellphone data to locate and arrest undocumented immigrants?

By Jacob Alabab-Moser
YES

U.S. Immigration and Customs Enforcement purchased location data generated from cellphone activity and used it to identify and arrest immigrants, according to people familiar with the matter that spoke with the Wall Street Journal. ICE and other immigration agencies like U.S. Customs and Border Protection have been buying large commercial datasets since at least 2017 from Venntel, a small location-based marketing company. The location data is harvested from smartphone apps.

In December 2020, the inspector general of the Department of Homeland Security, which oversees ICE and CBP, announced an investigation into "policies related to cell-phone surveillance devices."

A letter written by the Inspector General to Congress from February 2021 recognized that the Fourth Amendment protects users' cellphone-produced location data—including GPS data produced automatically through the use of applications on cellphones—and that the government needs warrants to access it.

ABOUT THE CONTRIBUTOR
Between 2020 and 2022, under close editorial supervision, Gigafact contracted a group of freelance writers and editors to test the concepts for fact briefs and provide inputs to our software development process. We call this effort Gigafact Foundry. Over the course of these two years, Gigafact Foundry writers published over 1500 fact briefs in response to claims they found online. Their important work forms the basis of Gigafact formats and editorial guidelines, and is available to the public on Gigafact.org. Readers should be aware that while there is still a lot of relevant information to be found, not all fact briefs produced by Gigafact Foundry reflect Gigafact's current methods and standards for fact briefs. If you come across any that you feel are out of date and need to be looked at with fresh eyes, don't hesitate to contact us at support@gigafact.org.
