He said he accepted the resignation of Kathy Miller, who has been organizing Trump's campaign in Mahoning County, following her "inappropriate comments."

Miller also released a statement apologizing for her "inappropriate" comments and reiterating that she was not speaking on behalf of the campaign.

Miller's remarks to The Guardian quickly gained national attention Thursday, coming as the GOP presidential nominee has in recent weeks tried to court African-American voters.

"I don’t think there was any racism until Obama got elected. We never had problems like this," Miller had said in the interview.
