Georgia Secretary of State Brian Kemp's office announced it has opened an investigation into Georgia's Democratic Party after a failed hacking attempt on the state's voter registration system Saturday evening.

The news comes just days before the midterm elections, in which Kemp is in a tight battle with Democrat Stacey Abrams to be governor.

"While we cannot comment on the specifics of an ongoing investigation, I can confirm that the Democratic Party of Georgia is under investigation for possible cyber crimes," said Candice Broce, press secretary for the Georgia secretary of state, said in a statement Sunday. "We can also confirm that no personal data was breached and our system remains secure."

The press release from the office said that federal partners, including the Department of Homeland Security and Federal Bureau of Investigation, have been alerted.

The news comes after a federal judge ruled the state must ease "exact match" rules, which present hurdles to voters flagged as noncitizens because of discrepancies on their voter registrations. The ruling was viewed as a blow to Kemp, as Democrats said his office had engaged in "voter suppression efforts."

Kemp, a Republican, faces a strong competitor in Abrams, whose candidacy is attracting some star power in the final days before the Nov. 6 election, including media mogul Oprah Winfrey. Kemp has a slim 1.1 percentage point lead over Abrams in the RealClearPolitics aggregate of recent polls.

Asked about the investigation Sunday morning on CNN's "State of the Union," Abrams said she hadn't heard anything about it yet, but did call it "desperate attempt" by her opponent to distract voters in the final days of the election cycle.

"I've heard nothing about it. And I would -- my reaction would be that this is a desperate attempt on the part of my opponent to distract people from the fact that two different federal judges found him derelict in his duties and have forced him to allow absentee ballots to be counted and those were who being captive by the exact map system to be allowed to vote," Abrams said.

"He is desperate to turn the conversation away from his failures, from his refusal to honor his commitments, and from the fact that he is part of a nationwide system of voter suppression that will not work in this election. Because we are going to outwork him, we are going to outvote him, and we are going to win."

Kemp has faced calls to resign as secretary of state while he stages his campaign, including by Abrams, as he has faced controversy related to voter registration.
