US intelligence officials on Friday discounted the possibility of foreign countries mass producing fake ballots to interfere in the November elections, contradicting President Donald Trump’s continued insistence that mail-in voting poses a significant threat to election security. The closed-door House briefing was led by the US intelligence community’s top election official, Bill Evanina, and senior intelligence officials who specialize in election security. Officials dismissed the possibility of foreign powers being able to interfere on a mass scale to produce and send fake ballots to voters and election authorities, a source said. The issue of forged ballots only came up when a lawmaker asked about it, a source in attendance told CNN. Evanina didn’t raise any alarms about that possibility, the source said. . . .

“Mail-in voting has already become an issue among partisan political voices, which makes it a target for threat actors to exploit,” the assessment read. “These threat actors may mislead and confuse the public about the mechanics of mail-in voting, and leverage limited understanding regarding mail-in voting processes, in order to cause chaos and provoke distrust in the election administration and electoral results.”
