Earlier this month Motherboard revealed that AT&T, T-Mobile, and Sprint had been selling real-time location of customers’ cell phones that ultimately ended up in the hands of bounty hunters and people unauthorized to handle the data. To verify this, Motherboard paid a bounty hunter source $300 to locate a T-Mobile phone, which successfully pinpointed the device to a specific part of Queens, New York.

Now, a group of 15 senators is calling on the Federal Communications Commission (FCC) and Federal Trade Commission (FTC) to investigate how telecommunications companies share their customers’ location data.
