The top U.S. counterintelligence official on Friday warned that Russia, China and Iran will all try to interfere in the 2020 presidential election, with Russia already trying to undercut presumptive Democratic candidate Joe Biden.
In an unusual public statement, William Evanina, director of the National Counterintelligence and Security Center, said those countries were using online disinformation and other means to try to influence voters, stir up disorder and undermine American voters' confidence in the democratic process.
Foreign adversaries also may try to interfere with U.S. election systems by trying to sabotage the voting process, stealing election data, or calling into question the validity of election results.
"It would be difficult for our adversaries to interfere with or manipulate voting results at scale," Evanina insisted.
