I’m pretty sure those calls were made by the New Black Panther Party:

The Kansas attorney general has opened an investigation into reports that voters across Kansas have received calls giving them a slew of false information about the election: That the election has been moved to Wednesday, that they need to bring their voter registration cards to the polls and that they need proof of homeownership to vote.

“That’s a felony,” AG spokesperson Gavin Young tells TPMmuckraker. Young said the complaints were not concentrated in a specific area, but came from all over the state. Contrary to original reports of robocalls, Young said many of the voters said they received live calls from real people.
