Georgia Republican gubernatorial candidate Brian Kemp announced on Sunday that he is investigating the state’s Democrats, whom he alleged without evidence are trying to hack Georgia’s voter registration system.

The baseless accusation from Kemp, Georgia’s secretary of state, came just two days before the midterm election, which will see him face Democrat Stacey Abrams in one of the tightest and most closely watched governor races in the country.

“While we cannot comment on the specifics of the ongoing investigation, I can confirm the Democratic Party of Georgia is under investigation for possible cyber crimes,” Candice Broce, Kemp’s press secretary, told Politico. “We can also confirm that no personal data was breached and our system remains secure.”

Kemp has made a similarly uncorroborated accusation before: In 2016, he claimed the Obama administration’s Department of Homeland Security had attempted to hack Georgia’s voter registration system. The department’s inspector general ultimately determined the allegation was false.

Abrams, who could become Georgia’s first African-American female governor, has leveled accusations of her own against Kemp. The 44-year-old claims her GOP opponent and his office are responsible for suppressing more than 53,000 votes in the state, 70 percent of which belong to minorities. Abrams and her allies have called for Kemp — who oversees the election as secretary of state — to drop out of the race. Kemp and his office instituted a law recently that called for an “exact match” between voters’ registrations and identification documents, something he has tried to explain away as simple “voter roll maintenance.”

In an interview on CNN early Sunday, Abrams responded to Kemp’s accusation against Georgia Democrats by saying he is “desperate to turn the conversation away from his failures.”

According to Politico,Kemp has been caught in several controversies besides the voter suppression scandal currently plaguing Georgia. He was reportedly criticized a few years ago for purging voter rolls for more than 1 million voters.

Former President Jimmy Carter, who previously served as governor of Georgia, recently called for Kemp to resign as secretary of state.
