The release of details into a massive data breach in the Georgia Secretary of State’s Office has been delayed until Monday afternoon.

Secretary of State Brian Kemp has said that a "clerical error" caused the breach, which included Social Security numbers, birth dates and drivers' license numbers of more than 6 million registered voters.

A statement released by Kemp’s office Friday — when the results of an internal investigative report were originally expected — said the work to detail what happened involves thousands of documents. That includes more than 5,000 emails, employee personnel files and internal policy and training reports. The office said documents would be made available to any member of the public for inspection.

Officials discovered the breach Nov. 13, a month after they had mailed compact discs to 12 organizations that regularly request data updates to the state's public voter files. The sensitive data appears to have been accidentally added to the discs.

Kemp has said all 12 data discs have either been recovered or destroyed, and that the data were not disseminated widely.
