Tau, Byron. 2020. U.S. news: DHS’s use of phone data will be probed. Wall Street Journal, Dec 03, 2020. (accessed December 3, 2020).

The department also buys software from Babel Street, another vendor that sells location-data products, according to public records.
Venntel and Babel Street didn’t respond to requests for comment.
