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.

Such data is widely used by the U.S. military and intelligence agencies for intelligence gathering overseas, according to public records and people familiar with the matter, but those agencies are largely barred from domestic monitoring.
