A leaked National Security Agency report published by The Intercept this week revealed Russian efforts to hack both a U.S. voting software supplier and more than 100 local U.S. election officials.
Now Sen. Mark Warner (D-VA) has told USA Today that American intelligence services have found evidence of Russian attacks against U.S. elections systems that are much broader than those revealed in the NSA's report this week.
"I don't believe they got into changing actual voting outcomes," Warner told the publication. "But the extent of the attacks is much broader than has been reported so far."
Warner also cautioned that he couldn't rule out a successful Russian hack of American voting systems in the future, as "none of these actions from the Russians stopped on Election Day."
The attempted hacks revealed in the NSA report showed that Russia had gone much farther in trying to compromise America's voting system than had been previously disclosed. Warner tells USA Today that he would like to release information about the states that were targeted by Russian hackers so they could move to shore up their systems ahead of the 2018 and 2020 elections.
"I really want to press the case," he said. "This is not an attempt to embarrass any state. This is a case to make sure that the American public writ large realizes that if we don’t get ahead of this, this same kind of intervention could take place in 2018 and definitely will take place in 2020."
