TALLAHASSEE (CBSMiami/CNN) – Members of Florida’s Congress will be briefed next week by the FBI about the claim that a Florida county was hacked by Russian intelligence in 2016.

Previous reporting and government announcements have established that the GRU, Russian military intelligence, created an email phishing campaign aimed at Florida county election employees in the summer preceding the 2016 presidential election. But it wasn’t until special counsel Robert Mueller’s report was published that the public learned the FBI had investigated a particular county for actually being hacked.

“[T]he FBI believes that this operation enabled the GRU to gain access to the network of at least one Florida county government,” the report claims.

The briefing will take place on May 16. The news was first reported by Politico.

During Russia’s multi-pronged election interference campaign of 2016 the GRU targeted VR Systems, an electronic pollbook manufacturer that a number of Florida counties use to maintain their voter registration databases. The GRU hackers then sent out phishing emails from Gmail accounts with VR Systems in its name, and with a malicious file attached to more than 120 county election officials.

Many of those emails were ignored, went to spam, or were properly flagged as a potential attack. The special counsel’s claim was the first public indication that someone fell for them.

Multiple government officials have repeatedly insisted that there is no evidence hackers changed any votes in either the 2016 or 2018 election, but have stopped short of claiming that hackers were never in a position to make it more difficult for people to vote.

The briefing is in response to a request that House Representatives Stephanie Murphy, Democrat of Florida, and Michael Waltz, Republican of Florida, made in a letter to Attorney General William Barr and FBI Director Christopher Wray.

Florida’s governor and Secretary of State have also said that they were unfamiliar with the 2016 hack and have requested answers.
