It came after several reliably Democrat strongholds announced that they would be open throughout the weekend to continue accepting ballots after early voting ended on Friday, which Republicans said was a violation of state law.

“It has come to our attention that Fulton County election officials are planning to open four election offices this weekend ‘to accommodate voters seeking to hand-return their absentee ballots.’ This is a blatant violation of Georgia law, subsection (d) of Code Section 21-2-385, O.C.G.A. § 21-2-382 which states ‘all drop boxes shall be closed when the advance voting period ends,’” Georgia Republicans said in a press release.

“This must be stopped immediately and those willfully breaking Georgia law should be held accountable. To make matters worse, the four election office locations are situated in areas of the county that will clearly favor Democrat candidates,” the press release said. “We are calling on state officials to take immediate action to stop this and maintain confidence in Georgia’s election integrity. Fulton County’s patently illegal acts give us no choice but to immediately file suit.”

The lawsuit threat came after Fulton County Registration Manager Kathryn Glenn informed county officials on Saturday that poll watchers would not be allowed in the counting centers.

“FYI – There are NO WATCHERS approved for ballot drop off! Do not let them in the building,” the email, which was sent to Fulton County election officials, said. “If they want to observe from the parking lot, you can’t stop that but they are not allowed to sit in the building. Have your security detail enforce it!!”
