Florida’s Republican governor, Rick Scott, said that Nelson’s claims amount to fear-mongering and that they are “senseless” and “irresponsible,” in a press release.

Gov. Scott is looking to take Sen. Nelson’s seat in the upcoming November elections.

In a joint letter released last month, both Sen. Nelson and Sen. Marco Rubio (R-Fla.) warned election boards across the state of Russian meddling as discovered by the Senate Intelligence Committee. The senators urged the election boards to reach out to the Department of Homeland Security and the FBI for additional resources.

“It is possible that additional activity has occurred and has not yet been uncovered,” the senators wrote.

Shortly after the letter, special counsel Mueller indicted 12 members of the Russian GRU by name on specific charges involving cyberattacks during the 2016 presidential elections. Several Floridian counties were compromised in that attack.

It is unclear whether Sen. Nelson’s recent statements are referring to the cyberattacks in 2016, a new round of intrusions, or if the hackers still have database access from 2016. When asked about the specifics, the senator won’t elaborate because of the “confidential” nature of the Senate Intelligence Committee’s findings.

But it does seem clear that Florida is still vulnerable to cyberattacks. Last week, DefCon hosted a hacking convention in Las Vegas. Thirty-five children were able to tamper with replicated U.S. voting systems. According to documents released by DefCon’s Twitter account, the hackers were able to change vote tallies and candidate names. One hacker was able to program a voting machine to project GIFs and play music.

An 11-year-old completed the fastest exploit. It took him 10 minutes to compromise a replica of Florida’s Secretary of State website.
