The demands are the latest move to pressure telecom companies, who said they would stop the sale of location data to third parties after Motherboard's coverage.
On Wednesday, Federal Communications Commission (FCC) Commissioner Jessica Rosenworcel demanded answers from AT&T, T-Mobile, Sprint, and Verizon on their sale of customers' phone location information to data aggregators. As Motherboard has shown in multiple investigations, this data, which sometimes included highly precise assisted-GPS data, ended up in the hands of bounty hunters, bail bondsmen, or private investigators.
The demands are the latest move to pressure telcom companies, who said they would stop the sale of location data to third parties after Motherboard's coverage. AT&T and T-Mobile previously told Motherboard that sale has ended, and Sprint said it would stop at the end of May.
