Iowa Secretary of State Matt Schultz says a dozen legal Iowa voters had their ballots thrown out in the last two years.
Schultz announced the errors Friday morning.
He launched a statewide review after learning in January that three Cerro Gordo County voters were wrongly listed as felons without voting rights.
That review found nine more cases of Iowans whose legal ballots were thrown out because a database of convicted felons wasn’t updated to show they had their voting rights re-instated.
Schultz says all of the voters have now had their rights restored.
Schultz has denied that his investigations into illegal voting are too blame. He says local law enforcement agencies aren’t updating the status of felons in their jurisdictions.
Schultz is leaving office this fall to pursue the Republican nomination for the third district congressional seat.
