Georgia closed an investigation into its governor's accusation that Democrats had hacked state voter registration systems, concluding there was no evidence to support the charge.

Catch up fast: Two days before the polls opened in the 2018 Georgia governor's race, Brian Kemp — then Georgia's secretary of state, in charge of overseeing the election — made his explosive charge.

Kemp was also the Republican candidate for governor in the election he was overseeing. He went on to beat Democrat Stacey Abrams by a slim margin of a little over 1%.

Why it matters: Now, 16 months later, a state attorney's general investigation reports there was zero evidence for Kemp's charges, the Atlanta Journal-Constitution reports.

Democrats say the accusation was a lie intended to suppress votes. Kemp's office continues to refer to the incident as a "failed cyber intrusion."

One face-plant thing: The investigation reported that there was indeed an attempt at breaking into the state's election systems — by the Department of Homeland Security, which was asked to perform such tests by Kemp's office.
