The Washington Post previously reported that computer systems in Illinois and Arizona were both successfully penetrated.
Manfra’s interview arrived alongside other U.S. officials’ recent warnings that Russian hackers may attempt to influence the 2018 midterm elections. In an interview on Tuesday, Secretary of State Rex Tillerson said Russia is already trying to interfere in the upcoming congressional elections.
“If it’s their intention to interfere, they are going to find ways to do that,” Tillerson said in a Fox News interview.
In late January, CIA Director Mike Pompeo said he has “every expectation” that Russia will try to target the midterms.
“I have every expectation that they will continue to try and do that,” Pompeo said in an interview with the BBC, “but I’m confident that America will be able to have a free and fair election [and] that we will push back in a way that is sufficiently robust that the impact they have on our election won’t be great.”
In September, the Homeland Security Department informed election officials in the 21 targeted states that Russian government hackers had tried to penetrate their voting machines in 2016.
