Roy Moore's Senate campaign said Monday it does not know why more than 1,000 fake Twitter accounts originating from Russia started following the former judge's account over the weekend, causing a spike in Moore's social media following.

The ex-Alabama Supreme Court Chief Justice's handle went from 27,000 followers on Friday to nearly 40,000 by Sunday. In a statement Monday, Moore's campaign said they called on Twitter to look into the matter, pointing out that Moore has not paid for followers and that all of his support on the social media site was "organically" earned. It appeared that the social media company scrubbed thousands of the fake followers from Moore's account, @MooreSenate.

Many of the Russian bots shared the same characteristics: Cyrillic characters and profile pictures of famous singers, including Brittney Spears, Christina Aguilera and Avril Lavigne.

Without evidence, the campaign pointed the finger at his Democratic opponent, Doug Jones.

The Moore campaign said it learned about the spike in followers over the weekend and confirmed that 1,000 of the fake accounts were Russian, but said it received media calls about the incident before it could "begin to review and take action on this matter."

A Moore spokeswoman said that raised suspicions that Jones or Democratic sources were behind the incident.

"We highly doubt that reporters across the country spend most of their free time on Sunday breaking away from church, family, and football to review the Twitter followers of various candidates across the country," the campaign said. "It is more likely that Doug Jones and Democrat operatives are pulling a political stunt on Twitter and alerting their friends in the media. It's not surprising that they'd choose the favorite topic of MSNBC and the Fake News outlets - the Russia conspiracy. Democrats can't win this election on the issues and their desperation is on full display."

Jones' campaign accused the Moore camp of making the allegations to deflect from the Republican candidate's controversies.

"Roy Moore is clearly prepared to tell whatever lies are necessary to distract from recent revelations that he misled the public and charitable donors by arranging for a secret deal to pocket more than $1 million," Jones campaign spokesman Sebastian Kitchen said in a statement. "While Moore is once again embarrassing the people of Alabama with another disgusting and pathetic lie, Doug spent Monday in North Alabama talking to a woman who is taking care of her 29-year-old son struggling with deadly medical issues, with firefighters, with business leaders, with workers who lost their jobs when a plant closed, and with other Alabamians.Maybe Moore should check with Vladimir Putin, who shares his views on depriving people of their civil rights."

Twitter declined to respond to questions from AL.com, with a spokesperson saying the social media giant does not comment on individual accounts "for privacy and security reasons."
