Russian government attempts to hack into U.S. election infrastructure were “much broader” than what was laid out in a report Monday in The Intercept, Virginia Sen. Mark Warner, the top-ranking Democrat on the Intelligence Committee, told USA Today in an interview Tuesday.

Warner’s claim was made in response to newly disclosed findings by the National Security Agency that Russian operatives had hacked into an election software company and attempted to spear-phish at least 122 addresses associated with local election officials, with uncertain results.

“The extent of the attacks is much broader than has been reported so far,” Warner said, referring to the report in The Intercept. “I don’t believe they got into changing actual voting outcomes,” he said, adding that he was pressuring intelligence agencies to declassify which states were hit, with the goal of helping them shore up their systems ahead of 2018 and 2020.
