The FBI briefed Florida members of Congress today on the Russian hacking of 2 counties' voter registration systems in 2016. The names of the counties remains classified, despite objections from both Republican and Democratic lawmakers. — Patricia Mazzei (@PatriciaMazzei) May 16, 2019 I attended a classified FBI briefing today on Russian hacking of voter databases in two #Florida counties.

The penetration of voter databases in two counties in Florida occurred after phishing emails were sent to election workers across the state.

"They sent these to all 67 counties," said Rep. Darren Soto (D-FL). "Unfortunately, two counties had employees that did click on those emails, and they gained limited access."

The outrage was bipartisan, as Florida lawmakers said there's no reason the identity of the counties should be a state secret, three years after the attempted hacking took place.

"They not only deserve to know what happened," Waltz said of voters in his state, "but they deserve to know what we're doing to protect the elections going forward."

Florida deserves answers! We were just briefed by FBI who confirmed Russia infiltrated 2 Florida counties through phishing emails during 2016 elections. The FBI maintains there is no evidence votes or voter information was altered, but we continue to review the matter. pic.twitter.com/QIgSGLTLGz — US Rep. Darren Soto (@RepDarrenSoto) May 16, 2019

Both parties stressed there was no evidence that voter databases were tampered with before the 2016 elections after Russians gained access to the two unidentified counties - but they say that’s no reason for the feds to hide the locations of where it occurred.

“What we have told them is that it is untenable to hold this information classified, and not to let the public know,” said Murphy.
