In North Carolina, voter suppression is being feared over a new round of automated phone calls targeting black households. The unidentified robocall features an African American voice falsely telling voters they must first send in a “registration packet” before they’re allowed to vote.

Robocall Voice: “Hello. This is Lamont Williams. In the next few days, you will receive a voter registration packet in the mail. All you need to do is fill it out, sign it, date and return your application. Then you will be able to vote and make your voice heard. Please return your registration form when it arrives. Thank you.”

Similar robocalls were used before the Ohio and Virginia primaries earlier this year. North Carolina voting rights advocates are calling for an investigation.
