Election security: Officials say 2024 election saw only 'minor' disruptive activities

A Georgia poll worker was arrested Monday and charged with allegedly sending a letter threatening to bomb an elections office in the state's Jones County last month, the Justice Department announced.

Nicholas Wimbish, 25, allegedly sent the threat after he had a verbal argument with a voter in the Jones County Elections Office on Oct. 16, according to prosecutors.

The following day, he allegedly mailed a letter to the Jones County elections superintendent purporting to be from the unidentified voter that stated Wimbish had "give[n] me hell" and was "conspiring votes" and "distracting voters from concentrating," according to prosecutors.

The letter allegedly stated that Wimbish and others "should look over their shoulder" and that the "young men will get beatdown if they fight me" and "will get the treason punishment by firing squad if they fight back," according to the DOJ.

The letter was allegedly signed, "PS boom toy in early vote place, cigar burning, be safe," prosecutors said.

During an interview with the FBI on Oct. 23, Wimbish allegedly blamed the letter on the voter he had interacted with, according to the complaint. During a search of Wimbish's personal computer, the letter was allegedly found in the print spooler, according to the complaint.

Wimbish faces several charges including mailing a bomb threat, conveying false information about a bomb threat, and making false statements to the FBI. He faces a maximum sentence of 25 years in prison on the cumulative charges if convicted, prosecutors said.

Court records do not list any attorney information for Wimbish.

The Maryland State Board of Elections released a new statement on Monday aimed at correcting disinformation about ballot marking devices.

"Ballot marking devices do not flip or switch votes," the statement read. "Unfounded claims of machines flipping votes have resurfaced and circulated in many elections."

The board said it has not been able to substantiate any claims "of vote flipping or changing of votes by a ballot marking device," and said any such allegation must be submitted as an administrative complaint along with an "affidavit sworn under the penalties of perjury."

While speaking to a large crowd in Atlanta on Monday, Sen. JD Vance urged voters in Georgia to go out tomorrow to cast their ballots while reminding them how close the race in the state was in 2020.

"Tomorrow is the day that we vote for lower grocery prices and more affordable housing," he said. "Tomorrow is the day that we vote to close the border and make Donald J. Trump the president of the United States."

Vance referenced that Trump lost Georgia to President Joe Biden by fewer than 12,000 votes.

"I didn't realize how small this was in 2020. Georgia was decided by less than 12,000 votes," he said. "That is crazy."
