The Federal Communication Commission (FCC) identified Lingo Telecom, a Texas-based wireless provider, as the company that transmitted deepfake robocalls impersonating President Biden. Walter Monk and the entity “Life Corp” were named as the culprits who created the deepfake calls. The FCC sent the Lingo a cease and desist letter, according to a press release sent to Gizmodo Tuesday, threatening to permanently block the company’s operations.

“Lingo Telecom, LLC is apparently originating illegal robocall traffic,” said the FCC in its cease and desist letter. “Failure to comply with the steps outlined in this letter may result in downstream providers permanently blocking all of Lingo’s traffic.”

The FCC worked with the New Hampshire Attorney General’s Office to identify Lingo as the company that facilitated deepfake robocalls ahead of a presidential primary last month. New Hampshire Democrats received AI-generated phone calls, made to sound like President Biden, advising them to refrain from participating in the upcoming primary. Regulators say Lingo has violated voter suppression laws by allowing these deepfake calls to originate on its network.

Lingo did not immediately respond to Gizmodo’s request for comment.

Notably, Lingo did not create the calls, but it did allow them to be transmitted on its network. The company identified the entity “Life Corp” as the group that created the calls in the first place. However, wireless providers have a legal obligation to protect their networks from transmitting illegal traffic.

New Hampshire Attorney General John Formella named an individual, Walter Monk, as the person behind Life Corp’s robocalls in a press conference on Tuesday. Lingo Telecom has since suspended services to Life Corp. At this time, it is unclear what Life Corp does. A call monitoring service estimates that between 5,000 and 25,000 robocalls were made to New Hampshire voters. Regulators are investigating whether ElevenLabs software was used to create the deepfakes, according to the Attorney General.

This is not the first time Lingo has been the subject of an illegal robocall investigation. Since 2021, the Texas phone company has been identified as a provider of 61 illegal calls originating overseas. This is also not Life Corp’s first rodeo with the FCC, according to the letter. The entity was issued a citation for delivering illegal robocalls to residential lines back in 2003.

Last week, the FCC pushed to outlaw AI-generated robocalls under the Telephone Consumer Protection Act of 1991. The FCC noted in a statement to Gizmodo that its action would help state Attorneys General prosecute the originators of deepfake robocalls. In the last few months, AI deepfakes have wreaked havoc on pop culture, the finance world, and even our democratic process.
