An arrest warrant has been issued for a 53-year-old petition circulator.

Mark Brown of Tulsa, Oklahoma is accused of three felony counts of false swearing to a circulator's affidavit. He was paid to collect signatures to get a measure to ban affirmative action on the November ballot.

According to an arrest affidavit, the Lancaster County Election Commissioner became suspicious after spotting a pattern on petitions Brown turned in. Two names in a row would have the same last name and address, as if both a wife and husband had signed. But in fact, there was no one by the second name listed as a registered voter.

Police say a writing comparison turned up 29 names and addresses Brown was believed to have written himself.
