In what appears to be the first case of a problem that experts have long feared, some voters have received robocalls that sound like President Biden telling them not to vote, a message that “appears to be artificially generated” and should be ignored, says the Attorney General’s Office.

The message, which was sent on Sunday sounded as if Biden was saying “your vote makes a difference in November, not this Tuesday.”   

”These messages appear to be an unlawful attempt to disrupt the New Hampshire Presidential Primary Election and to suppress New Hampshire voters.  New Hampshire voters should disregard the content of this message entirely,” the Attorney General’s Office said in a release. “Recipients of this message are additionally encouraged to send an e-mail to the Department of Justice Election Law Unit (electionlaw@doj.nh.gov) identifying (1) the date and time they received the call or message; (2) the origin of the call or message; (3) the content of the call or message; and (4) any other relevant information.”

Kathy Sullivan, a former state Democratic Party chair who helps run Granite for America, a super-PAC supporting the Biden write-in campaign, said she alerted law enforcement and issued a complaint to the attorney general after multiple voters reported receiving the call Sunday night.

“This call links back to my personal cell phone number without my permission,” she said in a statement. “It is outright election interference, and clearly an attempt to harass me and other New Hampshire voters who are planning to write-in Joe Biden on Tuesday.”

It was unclear how many people received the call but a spokesperson for Sullivan said she heard from at least a dozen people who got it Sunday night.

Advances in the technologies called artificial intelligence have made it extremely easy to generate audio recordings and even video recordings that look and sound as if they were produced by somebody else. This has raised concern about misinformation during election season.
