Hackers from Russia gained access to voter databases in two Florida counties before the 2016 presidential election, Gov. Ron DeSantis said. While the hackers didn’t compromise election results or manipulate any data, the fact that they gained access at all is significant.

DeSantis and state law enforcement officials learned about the intrusion from the FBI and Homeland Security last week, though he can’t reveal which counties were affected per a non-disclosure agreement. The FBI is set to brief members of Congress on the situation Thursday, and DeSantis’ predecessor, Sen. Rick Scott, tomorrow.

The Mueller report on Russian interference in 2016 mentioned hackers gained access to at least one Florida county’s network. DeSantis, who came into office in January, didn’t know of the intrusion beforehand, and nor did Scott, according to a spokesman.
