Iowa Secretary of State Matt Schultz says investigations by the DCI have led to the restoration of voting rights for a dozen Iowans.
In the past two years, 37 provisional ballots were correctly rejected because the voter had a felony conviction.
Twelve were incorrectly rejected. Of those, three were found not to be felons, two felons had data entry mistakes and seven had their rights restored by executive orders.
Shultz sent the information to the appropriate county auditors to fix the errors.
The secretary has also created a task force to work on the inaccuracies in the felon file used for voter registration.
