Iowa state officials have referred nine people to Iowa county attorneys, saying the nine voted twice in the November election last year.

The Iowa secretary of state's office said in a news release Friday that the nine are suspected of voting in Iowa after casting ballots in other states. There were 27 suspected instances of people voting first in Iowa and then other states during the same election.

VOTER FRAUD EXISTS -- DESPITE WHAT YOU MAY HEAR

Four of the nine cases are believed to have occurred in Polk County, with one each in Johnson, Mitchell, Sioux, Story and Warren counties.

The 27 other instances of suspected double voting have been shared with voting officials in the respective states.

The information was discovered through Iowa's partnership with several states in the Electronic Registration Information Center. The states share data to improve the accuracy of voter rolls and enhance voter confidence.

"One fraudulent vote is too many. It nullifies a legally cast vote," Iowa Secretary of State Paul Pate said.
