"Us and our office, and I think the rest of the state, is getting a little tired of always having to wait on Fulton County and always having to put up with their dysfunction," Raffensperger said on Tuesday. "They can still make it by our midnight Wednesday deadline, but they seem to want to make it a dramatic finish."
Georgia is nearing 50 counties completed (out of 159) for the recount, and Fulton is the largest that is incomplete, Raffensperger said.
Fulton County has made headlines for issues counting votes, including a newly purchased Dominion Voting Systems mobile server crashing and a reporting issue requiring officials to rescan more than 300,000 ballots.
"The real issue is a Fulton County employee made several compounding errors," Raffensperger said. "Instead of following the procedures that my office and the vendor laid out, Fulton County once again cut corners. The biggest one being [the employee] backed up the election project on the server itself instead of on an external backup. Because of that decision, they lost the ability to upload hundreds of thousands of scanned ballots."
"Yesterday announced they will scan from 7 a.m. to 11 p.m. today," Raffensperger said. "As of an hour ago, Fulton County only had eight of the 17 high-speed scanners going because of staffing shortages."
Fulton County pushed back against Raffensperger on Tuesday.
"I'm still not clear why they continue to pick on Fulton County, Georgia," Rob Pitts of the Fulton County Board of Commissioners said, according to 11Alive's Christie Dietz. "We are the largest county. I can't speak to the other counties, but I can tell you without shadow of a doubt, there was no hanky-panky with the recent election."
President Trump has repeatedly slammed Raffensperger and Georgia Gov. Brian Kemp, who are both Republicans. Trump called on Kemp to override Raffensperger on matching signatures during the state's recount on Monday.
A spokesman for Kemp issued a statement in response Tuesday morning, saying that “Georgia law prohibits the governor from interfering in elections.”
“The secretary of state, who is an elected constitutional officer, has oversight over elections that cannot be overridden by executive order,” Kemp spokesman Cody Hall said in a statement. "As the governor has said repeatedly, he will continue to follow the law and encourage the secretary of state to take reasonable steps – including a sample audit of signatures – to restore trust and address serious issues that have been raised.”
