Rubio, a member of the Senate Intelligence Committee, told the Times that there was an intrusion into a county’s elections system but that the target or targets were not notified.

He said national security officials opted to issue a blanket warning about hacking efforts as a way to protect intelligence methods.

"Everybody has been told what it is they need to do to protect themselves from the intrusion," Rubio said. "I don’t believe the specific victims of the intrusion have been notified. The concern was that in a number of counties across the country, there are a couple of people with the attitude of: 'We’ve got this; we don’t need your help. We don’t think we need to do what you are telling us we need to do.'"

Rubio told the newspaper that the hackers were "in a position" to change voter roll data, but it does not appear they did so.

"My biggest concern is that on Election Day you go vote and have mass confusion because voter registration information has been deleted from the systems," he said.

Scott, who was governor during the 2016 election, sent a letter to the FBI last week asking it to confirm the hacking. For his part, DeSantis has expressed frustration with what he says is a lack of transparency from federal authorities.

"They won’t tell us which county it was. Are you kidding me?" he said at a Thursday press conference in Miami. "Why would you have not said something immediately?"
