The voter registration database of a small county in the Florida panhandle was breached by Russian government hackers in 2016, according to two U.S. officials.

The Russian military spy agency, the GRU, was responsible for the penetration of Washington County’s database, according to the two officials, who spoke on the condition of anonymity to discuss a sensitive matter. The county has a population of about 25,000.

Carol F. Rudd, county elections supervisor, declined to comment on the breach but said it’s important for federal, state and local officials to be able to communicate confidentially. “If each agency gets suspicious of the other’s ability to follow the rules of confidentiality, then those tenuous lines of communication quickly break down,” she said in an email. “That would set our security capabilities back years and severely compromise our ability to protect our elections. THAT would be a big win for the Russians going into 2020.”

Then-Florida Secretary of State Ken Detzner said he was “prohibited by law from commenting.” But “the citizens deserve and have a right to know important things with regard to their election security. Over time, it’ll come out.”
