"Federal law enforcement divisions have been purchasing commercial databases with cellphone location data to support immigration and border enforcement efforts, The Wall Street Journal reported Friday.

The Department of Homeland Security (DHS) has used the data to detect undocumented workers and other migrants entering the country illegally, according to the Journal.

Immigration and Customs Enforcement (ICE) and Customs and Border Protection (CBP) — both divisions of Homeland Security — have reportedly utilized the data in a variety of ways."
